Multi-String value named OptionalNames with Data as <aliasnames> in the following registry key and restart the Server service.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters

You can specify alias name details in the Network Traffic Redirection section of the High Availability Properties.

Enhancements

Effective with CA ARCserve RHA r16.5 SP1 release, replication and data rewind performance on replicas has significantly improved.

Known Issues

The following issues are known to exist in this release:

■ _{For a Full System HA scenario: When the master server has two NICs (network}

interface controller), and the first NIC is disabled. Then after switchover, the network adapter of the newly created virtual machine fails to map to the correct NIC.

■ For Full System scenarios: When the master server is Windows 2012 with Hyper-V role, then the virtual machine created during Assured Recovery, switchover, or the Start VM operation, fails to start. The failure to start is caused by a system

exception related to winhv.sys. The workaround is to remove the Hyper-V role on the master server and synchronize again.

■ _{On Windows 2012, the performance counters for CA ARCserve RHA are not}

displayed correctly. One of the workarounds is to copy the following files to the \windows\system32.

■ ibeay32.dll

■ ssleay32.dll

■ thl.dll

■ trc.dll

Dropped Systems and Platforms Support (see page 22)

New Features and Enhancements

CA ARCserve RHA r16.5 supports the following features:

CA ARCserve Central Host-Based VM Backup Support

CA ARCserve RHA provides native support for CA ARCserve Central Host-Based VM Backup with a new server type selection. CA ARCserve RHA connects to the Central Host-Based VM Backup server to get the policy and related backup destination hosts with corresponding virtual machines. You can select the backup host and its virtual machines. This replicates the backup files (created by CA ARCserve D2D) of those virtual machines.

Microsoft Windows Server 2012 Support

Effective this release, CA ARCserve RHA supports Microsoft Windows Server 2012. You can install the RHA Control Service and the Engine on the Windows Server 2012 and create scenarios.

The following features are supported:

Storage Spaces

Data Deduplication

4KB logical sector size

(14)

New Features and Enhancements

Full System Cascade Scenario to Add Multiple Replicas

Effective this release, you can create a Full System cascade scenario to add multiple Replica servers at different levels. You can create any topology for a Full System scenario to make it flexible even if the appliance hosts are at different virtual platforms. Each appliance host has its own virtual platform and virtual machine settings and you can specify these settings separately. You can also perform various operations such as AR testing, Start/Stop VMs, Delete VM resources for each appliance host and related virtual platform. For manual switchover, you can choose which replica to be switched over to.

MS SQL FILESTREAM BLOB Data Support

Effective this release, you can protect MS SQL BLOB data. When the master server has MS SQL server enabled FILESTREAMS, the RHA engine discovers and replicates all BLOB data. The engine discovers and replicates even if the BOLB data is stored in locations other than the database files. The root directory also adjusts automatically according to the BLOB data path.

(15)

Enhancements

Effective with r16.5 release, CA ARCserve RHA provides the following enhancements:

■ _{Microsoft Hyper-V 3.0 Support for Full System Scenarios:}_{Full system scenario}

supports MS Hyper-V 3.0. You can now select Hyper-V 3.0 as virtual platform.

■ Unified Extensible Firmware Interface (UEFI) Firmware Support: Full system scenario supports server with UEFI firmware as the master server. Make sure that the virtual platform also supports the UEFI firmware.

■ Dynamic Disk support for Full System Scenarios: Dynamic disks such as simple, spanned, striped, mirrored, and RAID-5 volumes are supported. The dynamic disks include both MBR and GPT partition types. Both the master and replica support dynamic disks.

■ _{4K Sector Size Hard Disk Support for Full System Scenarios:}_{Full System scenarios}

support 4K sector size hard disk. RHA supports 4K sector size hard disk on the following operating systems.

■ Windows Server 2008

■ Windows Server 2008 R2

■ Windows Server 2012

■ Preserve the Destination Volume Layout for Full System BMR Scenarios: To keep the current volume on the bare metal machine (destination machine), an option, "Preserve Existing Volumes on Destination", is included while creating a scenario for bare metal machines.

■ _{Modify VM Settings Dynamically:}_{You can now dynamically modify VM settings for}

Full System scenarios while the scenario is running. The settings include, CPU cores, Memory size, Virtual Machine name, Assured Recovery Network Adapter Mappings, Physical Network Mappings, and EC2 Instance Type.

■ _{Oracle Multiple Instance Support:}_{You can protect multiple Oracle DB instances}

that are installed on the same Windows host. RHA engine now monitors all the services for each oracle database instance. You can now select multiple instances on the "Select Oracle Instances for Replication" screen while creating a scenario. RHA also lets you specify "sys as sysdba" to log in to the database.

■ _{Multiple Mount Point Support in the RHA Root Directories on Linux:}_{The XOFS}

driver can now be mounted to the sub mount points in the root RHA directories on Linux. This feature is applicable to the following Linux versions:

■ Red Hat Enterprise Linux

■ SUSE Linux Enterprise Server

■ CentOs Linux

(16)

This feature lets RHA protect multiple file systems mounted on the same RHA root directory. Now when a scenario runs, RHA mounts XOFS on the specified RHA root directory. In addition, RHA scans whether there are sub mount points in the RHA root directory and automatically mounts XOFS driver on each sub mount point.

■ Additional Region Support for Amazon EC2: Now you can create a full system HA or replication scenario with an EC2 replica for the following five regions.

■ Asia Pacific (Sydney)

■ Asia Pacific (Tokyo)

■ EU West (Ireland)

■ South America (Sao Paulo)

■ US East (Virginia)

■ _{Microsoft Hyper-V Scenario Supports Failover over a WAN:}_{Hyper-V scenarios can}

failover over a WAN, you can change the virtual machine IP address when

performing switchover/failover. You can also set network adapters using the GUI.

■ _{Full System Scenario Template with Predefined Replica Details}_{: The Full System}

scenario template is enhanced to let you include replica details while creating the template. This created template has the predefined replica details that you can use multiple times to create scenarios. When you create the scenario, just specify the master server details and reuse the predefined replica details.

■ Include Newly Created Virtual Machine Option for the Central Host-Based VM Backup Scenarios: This option lets you replicate all sub folders in the main host backup folder when you run the scenario. Any newly created VM backup folders are also replicated. Only the folders of the unchecked virtual machines are excluded. Those folders are marked as excluded folders. If you do not select this option, only the selected backup folders are replicated.

■ Improved Scenario Authentication and Multitenancy Support: The scenario authentication is improved and is more secure. This allows you to have a very secure multitenancy replication. ARCserve RHA verifies the following conditions at the beginning and stops the scenario when these conditions fail.

1. Scenario level credentials for each host.

2. Host level credentials for each host. The host level credentials override scenario level credentials. If the host level credential is blank or is not set, then RHA automatically uses scenario level credentials.

3. User has Full Control Permission to the specified parent folder.

Encrypt Data During Transfer: This Replica property is enhanced and you have these four options: No encryption, AES-128, AES-256, and User Configured.

■ _{Current User option in the Remote Installer Wizard:}_{The Current User option is}

added to let you set the Service Logon Information to the current user. This option lets you log on to the CS (Control Service) using the current account you logged in with.

(17)

Included Fixes

■ Reports as Email Attachments: You can receive all CA ARCserve RHA reports in the HTML format as email attachments.

■ _{SMTP Authentication Support:}_{The following three SMTP authentications are}

supported for event notifications and reports. You can set mail server, submission port, user credential, and proxy settings.

(18)

Known Issues

■ When upgrading from a previous release, running scenarios may fail to start after the upgrade process completes. This behavior occurs during the process of

upgrading the Engine. The upgrade process should stop running scenarios and then restart the running scenarios after the upgrade process completes. However, the upgrade process interprets the running scenarios as having new user name and passwords (in error), which prevents the upgrade process from restarting the scenario automatically.

To correct this problem, manually start the scenarios that were running before the upgrade started using Run, after the upgrade process completes. Use the Run control from the user interface.

■ If you are unable to reset the CA ARCserve RHA interface back to the default after rearranging panels using the dock manager, perform the following steps:

– Find the running directory for the ws_gui.exe file.

– Close the interface.

– In this directory, delete the following files: dock_layout.xml, dock_layoutdefault.xml.

– Relaunch the interface.

The interface arrangement is returned to the default layout.

■ _{Rewind is not supported for applications that use TxF functionality (IIS 7.0)} ■ When remotely installing the CA ARCserve RHA Engine on Windows Server 2008

systems, installation fails if you log in to the Control Services as a local system. To avoid this, use a Domain Admin account to access the Control Service.

■ When you use the Switch Computer Name redirection method on computers running Windows Server 2008 R2, manually rejoin the Master server to the domain after failover.

■ When a NetBIOS server name is longer than 15 characters, the CA ARCserve RHA Manager may fail to launch from the Overview screen if a proxy is set in Internet Options. The proxy server can only resolve DNS names, not NetBIOS names.

■ After 72 hours, the bare metal machine will reboot automatically (applicable for full system scenarios).

■ _{When you boot the bare metal machine after recovery, some drivers may be}

missing. Manually install these drivers.

■ When you upgrade the RHA engine, all existing bookmarks and rewind points are lost.

■ For the Move IP redirection method on Linux platforms, you can configure the IP only by the ipconfig command.

(19)

Known Issues

■ When you install the RHA engine on clusters using Remote Installer, you must install the Engine on both physical nodes and select a physical node instead of a cluster name.

Microsoft SQL Server

■ In SQL Server scenarios, the cluster server name is changed after switchover, but the server is not rebooted even if the reboot property is set.

■ Do not install SQL data files at the root directory of boot volumes such as C:\. During replication, the target files may fail to open on the Replica server, causing errors.

■ _{Assured Recovery scenarios fail on SQL Servers running in a workgroup. This is}

because:

– The Replica local admin account is overwritten by the Master local admin account in the Master database.

– The application uses Windows authentication to log into SQL Server.

To avoid this problem, use SQL authentication or switch computer name redirection method.

(20)

Known Issues

Full System Protection

■ _{For Citrix Xen scenarios, we are unable to unmount a disk on a virtual machine}

when files stored on the disk are in use.

■ Depending on your Windows license type, you may need to reactivate your virtual machines after Full System Assured Recovery or switchover. Visit the Microsoft website for more information about reactivation policies.

■ In "mixed environments" in which supported and unsupported versions of ESX are managed by a vCenter Server, full system scenarios may fail because VMDK cannot be mounted on the appliance specified. To avoid this situation, verify all versions of ESX in your environment are supported.

■ When performing a restore process for a Full System scenario, manually stop the application services on the Master or that application may become corrupt after restore. If the application is corrupted after a restore, stop the application services, restore to the same bookmark again to solve the problem.

■ _{While synchronizing a Full System scenario if you get the "Access is denied"}

message, then consider the following points:

■ Use the Volume synchronization instead of the File or Block synchronization.

■ Set engine service logon account to Local System. The error could be because the master engine service logon account is local or domain administrator.

■ On Microsoft Windows 2012, the File Server Resource Manager feature occupies some fixed volume space. For full system scenarios, this may lead to insufficient disk space for CA ARCserve RHA to complete synchronization. One of the

workarounds is to disable the Windows server 2012 File Server Resource Manager feature and then run FSHA.

CA ARCserve RHA for MMC

■ The MMC may fail to connect to the license server under these conditions:

– The default HTTP or HTTPS proxy is configured on the same host where the MMC is running.

– The address of the license server is not in the proxy bypass list.

– The proxy requires authentication to access the website.

The Windows account does not have the required privileges to access the proxy, which means the current MMC user is not authorized to use the proxy.

(21)

Known Issues

To avoid this situation, do the following:

– Specify the Control Service server in the HTTP proxy bypass list.

– Remove the HTTP proxy configuration in Internet Explorer so the MMC can connect directly to the Control Service.

– Authorize the current user to access the HTTP proxy server.

■ _{Note that the MMC connects to the Control Service with Windows Internet}

Configuration automatically; this setting can be changed by third-party applications.

■ CA ARCserve RHA Disk Resource does not ensure data integrity across multiple volumes in a Microsoft Failover Cluster. For applications that require data integrity between data sets, all data must be hosted on a single volume.

■ You may create CA ARCserve RHA Disk Resources only on the node that owns the cluster. For example, for cluster nodes A, B, C, and D where node A owns the cluster, Disk Resources can be created only on Node A.

Oracle Solaris 11

Before you create a scenario with the Move IP redirection method for Solaris 11, set related NIC/IP addresses to the manual mode in Solaris.

Linux

■ For any file operations on the root directory of the master, you must either disable SeLinux or change the SeLinux security context.

UNIX/Linux

■ On UNIX/Linux platforms, ARCserve RHA does not support "/" as root a directory.

Microsoft Windows 2003

■ When a Replica server is Windows 2003 and the Master server is Windows 2008 or higher, you can get the following error. This error is because Windows 2003 does not support Hard Links or Transactional NTFS (TxF) file system operations.

Unable to execute event Create hard link for

\\?\Volume{b8262eac-30ac-11e1-959c-000c29f6edbe}/<a-file-path> : Access is denied.(5)

■ When you perform BMR from a Windows 2003 machine, verify that the machine supports APIC motherboard and it is enabled. Otherwise, the machine fails to boot.

(22)

Dropped Systems and Platforms Support

Amazon Web Service (AWS)

■ _{During failover to AWS, ARCserve RHA replaces HAL (hardware abstraction layer) of}

the master to ACPI HAL (Advanced Configuration and Power Interface HAL). For a physical machine (old hardware) or VM with no ACPI support, failback does not work.

■ _{ARCserve RHA Bare Metal Recovery does not support Virtual Box virtual machines}

configured with SATA controllers.

NAT Environment

For HA cascade scenarios in a NAT environment, where CS and the non-default failover appliance hosts are not in the same sub-network. The virtual appliance cannot connect to CS when performing Manual Failover/Start VM/Stop VM/Delete all VM resources. The events are not displayed on the GUI because the appliance cannot initiate the connection to CS. You can find the detailed steps in engine logs of each hosts.

For Hyper-V HA Scenarios

When the protected VM has multiple network adapters connected to different virtual switches and you choose to customize the IP address using network mapping, the following problem may occur after switchover.

■ The network adapters in the VM are connected to wrong virtual switches at the Hyper-V replica and the network of the VM may not work properly.

To resolve this issue, manually change the virtual switch for each network adapter in the virtual machine setting using the Hyper-V Manager.

Dropped Systems and Platforms Support

CA ARCserve RHA r16.5 no longer supports Windows Server 2003, 2003 R2, or 2008 as Virtual Appliance for Full System scenarios.

Upgrade Considerations: If you cannot have a virtual appliance running Windows 2008 Server R2 or Windows Server 2012, you can continue using CA ARCserve RHA r16 SP2 for both the RHA engines and the RHA Control Service. Otherwise, the r16.5 RHA Manager prevents starting the existing Full System scenario.

Note: CA ARCserve RHA r16.5 Full System scenarios continue to protect Windows Servers 2003, 2003 R2, and 2008, that is, as master servers.

Chapter 4: CA ARCserve RHA r16 Service

Pack 2

This section describes new features, enhancements, and included fixes in CA ARCserve RHA r16 Service Pack 2.

Note: This Service Pack does not support upgrade from r16.5 alpha.

New Features and Enhancements

CA ARCserve RHA r16 Service Pack 2 supports the following features:

Restore Support to a Bare Metal Machine

Effective with this release, CA ARCserve RHA supports restoring data to a bare metal machine. You can restore to a bare metal machine (physical or virtual) either from a live system that has performed a failover/switchover or from a bookmark rewind point. This feature not only restores data but also builds the bare metal machine by installing the operating system, applications, and other necessary components.

A bare metal recovery provides the following benefits:

■ _{Builds a machine exactly similar to the Master before restoring data} ■ _{Recovers data even to a dissimilar hardware}

(24)

NAT Support

Effective with this release, you can deploy CA ARCserve RHA in a NAT (Network Address Translation) environment. This feature lets you have an RHA setup where host servers are behind a NAT device or a firewall. For example, you can have a setup where the Master is behind a NAT device whereas the Control Service and Replica are on a public domain.

To use this feature, CA ARCserve RHA provides the RHA NAT utility. You configure the RHA NAT utility on the host that is behind the NAT device.

(25)

Enhancements

Effective with this release, CA ARCserve RHA provides the following enhancements:

■ _{Volume Snapshot Management Support:}_{The volume snapshot has been simplified}

and you can set volume snapshots at one place. In addition, you can specify whether you want to have a snapshot while creating a bookmark. A check box is available for this option while creating a bookmark.

■ _{Advanced Bandwidth and I/O Throttling:}_{The bandwidth scheduler is enhanced to}

configure hourly bandwidth settings for the entire week. For example, you can set 256 KB for Monday, 9:00 AM or 192 KB for Wednesday, 4:00 PM.

■ _{Recover Active Server:}_{Now Full System scenarios support the Recover Active}

Server function. You can use this function to simulate switchover or switchback.

■ _{Start/Stop Virtual Machine:}_{A new option on the Tools menu has been added to}

stop or start a virtual machine. This option is applicable for a Data Recovery or High Availability full system scenarios.

■ Delete All VM Resources: A new option on the Tools menu has been added to delete temporary VM resources. This operation lets you delete temporary resources such as disk files, snapshots, and other temporary files.

■ VMware Distributed Virtual Switch: Support for the VMware Distributed Virtual switch has been added for full system scenarios. You can select the vSphere Distributed Virtual Switch during network mapping.

■ Proxy Support for Control Service: HTTP proxy support for RHA Control Service has been added. This service lets the Control Service connect to the RHA engine hosts using HTTP proxy servers.

■ Data Rewind Performance: The rewind point query function is restructured and the user interface has been redesigned. You can quickly search event points during rewind. The response time is fast even when there are up to million events.

■ Scheduled Bookmark: A new property, Enable Scheduled Bookmark, has been added to let you create a bookmark schedule for DB scenarios such as MSSQL and Exchange scenarios.

■ CAVSSSoftProv Service: The CAVSSSoftProv service is no longer required.

■ _{Log Collection Utility:}_{A log collection utility has been added. This utility can}

automatically retrieve Master, Replica, and Control Service logs along with event logs from the Master and Replica.

■ Create Application Consistent Snapshot: This feature lets RHA engine call

application VSS writers, such as the Exchange VSS writer and MSSQL VSS writer, to create application consistent snapshots. The snapshots are created on the master during the bookmark creation process.

■ _{Keep the Archive Attribute on the Replica:}_{A new property added to the}

Replication properties. If set to on, it retains the archive attribute on the replica during synchronization if master and replica files are identical.

(26)

■ Retain Local Account Name: A new property added to the Replication properties to retain the local name in the replica machine. Before you run a scenario, manually create the same local users or groups in both Master and Replica. Use this property for workgroup environments. This property is only applicable to Windows

machines.

■ _{DNS Redirection using the Update DNS Tool:}_{Use this tool to change the DNS A}

record of the master server to resolve to the IP address of the replica. You use this tool after you start or stop the VM using the Start/Stop VM feature. You can use this tool by running the update_dns.exe file in the RHA engine installation folder.

■ Offline Synchronization Support for Full System Scenarios: The offline synchronization is now extended to full system scenarios including forward, backward, and bare metal restore scenarios.

Known Issues

■ If you are unable to reset the CA ARCserve RHA interface back to the default after rearranging panels using the dock manager, perform the following steps:

■ _{Rewind is not supported for applications that use TxF functionality (IIS 7.0)} ■ When remotely installing the CA ARCserve RHA Engine on Windows Server 2008

systems, installation fails if you log into the Control Services as local system. To avoid this, use a Domain Admin account to access the Control Service.

■ When you use the Switch Computer Name redirection method on computers running Windows Server 2008 R2, you must manually rejoin the Master server to the domain after failover takes place.

■ When a NetBIOS server name is longer than 15 characters, the CA ARCserve RHA Manager may fail to launch from the Overview screen if a proxy is set in Internet Options. The proxy server can only resolve DNS names, not NetBIOS names.

■ _{After 72 hours, the bare metal machine will reboot automatically. This is applicable}

for full system scenarios.

■ _{When you boot the bare metal machine after recovery, some drivers may be}

missing. Manually install these drivers.

■ When you upgrade the RHA engine, all existing bookmarks and rewind points are lost.

■ _{For the Move IP redirection method on Linux platforms, you can configure the IP}

only by the ifconfig command.

■ When you instal RHA engine on clusters using Remote Installer, you need to install the Engine on both physical nodes and select a physical node instead of a cluster name.

Known Issues

Chapter 4: CA ARCserve RHA r16 Service Pack 2 29 Microsoft SQL Server

■ _{In SQL Server scenarios, the cluster server name is changed after switchover, but}

the server is not rebooted even if the reboot property is set.

■ Assured Recovery scenarios fail on SQL Servers running in a workgroup. This is because:

Full System scenarios do not support Dynamic disks on the Master server.

■ _{For Citrix Xen scenarios, we are unable to unmount a disk on a virtual machine}

■ _{When performing a restore process for a Full System scenario, manually stop the}

application services on the Master or that application may become corrupt after restore. If the application is corrupted after a restore, stop the application services, restore to the same bookmark again to solve the problem.

■ _{Upgrading to CA ARCserve RHA r16 SP2:}_{If you upgrade the RHA engine from}

previous releases to r16 Service Pack 2, you must synchronize the Master and Replica at least once to complete the upgrade.

■ _{While synchronizing a Full System scenario if you get the "Access is denied"}

message, then consider the following points:

■ Use the Volume synchronization instead of the File or Block synchronization.

■ Set engine service logon account to Local System. The error could be because the master engine service logon account is local or domain administrator.

(30)

Known Issues

■ _{The MMC may fail to connect to the license server under these conditions:}

– The Windows account does not have the required privileges to access the proxy, which means the current MMC user is not authorized to use the proxy. To avoid this situation, do the following:

■ Note that the MMC connects to the Control Service with Windows Internet

■ _{CA ARCserve RHA Disk Resource does not ensure data integrity across multiple}

volumes in a Microsoft Failover Cluster. For applications that require data integrity between data sets, all data must be hosted on a single volume.

■ _{You may create CA ARCserve RHA Disk Resources only on the node that owns the}

cluster. For example, for cluster nodes A, B, C, and D where node A owns the cluster, Disk Resources can be created only on Node A.

Before you create a scenario with the Move IP redirection method for Solaris 11, set related NIC/IP addresses to the manual mode inSolaris.

Linux

■ For any file operations on the root directory of the master, you must either disable SeLinux or change the SeLinux security context.

■ _{When a Replica server is Windows 2003 and the Master server is Windows 2008 or}

higher, you can get the following error. This error is because Windows 2003 does not support Hard Links or Transactional NTFS (TxF) file system operations.

Change Scenario While Running

Effective with this release, you may modify certain scenario properties without having to stop a running scenario or force a resynchronization. The properties you may modify include:

■ _{Spool settings} ■ Is Alive values

■ Bandwidth settings

(36)

Included Fixes

Cloud Support

Effective with this release, the following features are introduced:

Replicate to the Cloud

You may use an Amazon Web Services EC2 cloud instance as the replication target for your Windows Server data without having to manually provision the replica on EC2. Cloud Replication supports file and byte level replication, multiple EC2 instances running on AWS, scheduled, periodic and continuous replication in forward directions, and recovery from the Cloud.

Failover to the Cloud

You may use an Amazon Web Services EC2 cloud instance as a high availability target for full system protection without having to manually provision the replica on EC2. Failover to Cloud supports full system protection of multiple Windows 2003 and 2008 R2 servers to an online replication target in the EC2 cloud, application and server monitoring, continuous replication in a forward direction, and offline recovery from the Cloud.

Note: An active and configured Amazon Web Services EC2 account is required for these features. Amazon Web Services does not yet officially support Windows 2008 R2 and we have observed issues during testing with this environment.

Enhanced Cluster Support

Effective with this release, CA ARCserve RHA provides the following protection to Microsoft Failover Cluster 2008 systems:

■ Eliminates the single point of failure by providing an additional layer of off-site protection to Microsoft Failover Cluster 2008 deployments running in a shared storage configuration. CA ARCserve RHA delivers continuous replication so that the clustered application can survive a complete loss of the shared storage hardware.

■ _{Acts as a replication provider for Microsoft to enable the new geographically}

dispersed clustering feature introduced with Windows Server 2008 failover clustering. This high availability solution allows for the connection of cluster nodes through a local area network (LAN) or wide area network (WAN), spanning many miles, for a solution that provides automatic disaster recovery.

Secure Communication

Effective with this release, SSL 128-bit encryption for securing communication between on-premises and off-premises servers without using a third-party VPN is now supported.

Note: Secure Communication is not a VPN replacement and does not extend the local LAN or circumvent firewalls.
