Disk agent and Media agent
Volume Backup Disk Agent (VBDA
Raw Disk Backup Disk Agent (RBDA)
Volume Restore Disk Agent (VRDA)
Raw Disk Restore Disk Agent (RRDA)
Filesystem Browse Disk Agent (FSBRDA)
Robotic Media Agent (UMA)
Backup Media Agent (BMA)
Processes
• SH SYS /PROC=*OMNI* 00000482 OMNI$INET_BG679 HIB 5 568 0 00:00:00.13 614 608 N 00000483 OMNI$INET_BG691 HIB 5 569 0 00:00:00.09 614 608 N 00000484 OMNIADMIN_24924 LEF 5 603 0 00:00:00.09 493 615 S 00000485 OMNIADMIN_9580 LEF 5 607 0 00:00:00.08 493 615 SA OMNI$INET_BGXXX process is created for each disk agent and runs INET.EXE
A OMNIADMIN_XXXX process is created for each disk agent also and runs VBDA.EXE
Where the destination device runs on OpenVMS a further OMNIADMIN_xxxx process is created for every media agent and runs BMA.EXE
So in Data Protector if we create a backup job with many disks we can have several hundred processes running!!!
DA and MA flow
•
If Media Agent and Disk agent are on same
system then shared memory “is” used
•
Otherwise data flow is via TCP/IP (Lan backup)
•
System services used SYS$CRMPSC()
•
SSP issue SSPUX611_027 replaced by
SSPNT611_045
•
For performance recommend VBDA and BMA

Installation cont’d
• Before installing note …. For all Data Protector versions…
• On OpenVMS 8.3 and above, the installation displays the following message: %PCSI-I-CANNOTVAL, cannot validate [PATH]HP-AXPVMS-DP-A0611
-XXX-1.PCSI;1 -PCSI-I-NOTSIGNED.
product kit is not signed & thus no manifest file
• To avoid this “-I- ” run the install with /OPTION=NOVALIDATE_KIT.
• Cluster environment Installation
• Common system disk perform install once.
• However, the OMNI$STARTUP.COM procedure needs to be executed for each node
• If you use a cluster TCP/IP alias name, you can define a client for the alias name as well if you are using a cluster common system disk.

Media Agent configuration
•
Best practice is let Cell Manager control the
library and present tape drives to each SAN
based client
•
Use the Data Protector GUI to manually
configure or auto-configure
these devices.
•
When configuring in Manager GUI ensure
• If you restore to a location other that the original location, only the disk device and starting directory are changed. The original directory path is added to the
destination path to form the new restore location.
• If the Restore Time Attributes (-notouch) option is disabled during a restore, the last accessed date will be updated with the current date and time on ODS-5 disks. On ODS-2 disks, the original dates will be set on the files.
• Restoring to a different OS you may lose attributes, including ACLs.
• ODS-5 disk backups that have extended filesystem names (upper and lower case letters, Unicode characters, etc) may not be restored to an ODS-2 structured disk.
• During restore files are always locked whether the Lock Files during Restore (-lock) option is set or not
• The default device and directory for pre- and post-exec command procedures is
omni$root:[bin]. For alternative location you must specify Unix/dos style notation:
/SYS$MANAGER/SHUT_APP.COM
• If the Restore Protection Attributes (-no_protection) option is disabled, the files are created with the default owner, protection, and ACL.
• When specifying wildcard characters for Skip (-skip) or Only (-only) filters use '*' for multiple characters and '?' for single characters.
• Disk quotas are not supported. OMNIADMIN may be used or disable diskquota
•
The directory structure and the files are restored, together
with the following filesystem information:
– File and directory attributes
– ACL (Access Control List)
– Secondary file entries
– During an OpenVMS filesystem backup, files with multiple directory entries are backed up once using the primary path name. Secondary path entries are saved as soft links.
– For example, system specific roots on an OpenVMS system disk will have the SYSCOMMON.DIR;1 path stored as a soft link. The data for this path will be saved under [VMS$COMMON...].
– During a filesystem restore, these extra path entries are restored.
•
Full system disaster restore
–
OpenVMS system with Disk Agent required
–
OpenVMS WRITEBOOT utility can be used to make the
system disk bootable
•
Backup/ignore=interlock and nobackup setting supported
ZDB functionality
•
Zero Downtime Backup eg. EVA leverages
business copy to snap and backup volume
•
Not supported on OpenVMS however …
–
DIY
•
Pre exec - Com file to stop application or quiesce
•
Use SSSU to snap volume and present
•
Com file to change volume label and mount
•
Data Protector backup snapped volume via backup
server.
• Need Software Support contract for entitlement to patches
• Patch is a self extracting DPWIN_XXXX.exe for Windows. Asks which directory?
• After extraction .PCSI and .text files residing in specified directory. Next action is transferring .PCSI packet to OpenVMS client.
• Package file name should be in PCSI predefined format, for example: HP-AXPVMS-DP-A0510-2-1.PCSI for DP build A.05.10(2)
• Package file attributes should be the following: Record format: Fixed length 8192 byte records Record attributes: None
• $ set file/attribute=(rfm:fix,lrl:8192,rat:none) *.PCSI
• Patching always in Data Protector is full file replacement!.
•
Cell Manager cannot backup OpenVMS client.
–
FQDN and shortname resolution from server to
client and viceversa - Ping
–
Telnet thevmshostname 5555
–
Telnet cellmanagerhostname 5555
–
Tcpip show service omni
•
If using a file library in 6.20 there is a format
problem where it cannot be used.
Solution is upgrade TCP/IP 5.6 to ECO 5
• "Cannot append to medium (Invalid device block size 63KB, should be 256KB” or
"Cannot append to medium (Invalid device block size 256KB, should be 63KB”
The first happens when trying to append a VMS backup to a tape with windows data on it.
The second case when happens when appending a windows backup to a tape with VMS data.
• A Data Protector Client cannot be a member of two different cells. Import will fail with: [12:1625] Import Host Failed
• OMNI$ROOT:[CONFIG.CLIENT]CELL_SERVER.;1 . Type this file to confirm
that it contains a reference to the old cell manager: $ TYPE OMNI$ROOT:[CONFIG.CLIENT]CELL_SERVER.;1 olddpserver.hp.com
• Delete this file.
• Login to the new cell manager and perform the client import by opening up a command prompt and issuing the command: omnicc -import_host
myvmsserver
•
Restoring from a Data Protector backup from
Alpha to an Integrity Server
“CANNOT SET MODE” error message
•
Advisory available but not realistic in some
scenarios. Case still open …
•
Troubleshooting
–
HP Library and Tape Tools to test devices
•
Also this tool is multi platform (HP L&TT)
–
Are other clients having a problem?
–
Media Robot Utility – [ABSxxx]
–
OpenVMS Backup to test
–
SAN or LAN?
•
Performance
• SAN preferred than LAN. Examine session log to determine
• LANCP check speed of NIC, duplex if LAN based
• SAN polling – (Windows RSM, Mgt agents, HPLTO driver)
• Split disks over multiple jobs
• SYSUAF Omniadmin
• Increase concurrency from default of 4
• Defrag volumes
• Raw disk backups
• Avoid Enhanced Incremental feature on OpenVMS
– Used for detecting renamed files/moved files , ACL change
