Step Action
1 Launch the RecoverPoint Management Application and login as user admin, you probably have a session opened already.
Disable the consistency group. From the consistency group status window click on the Disable Group icon. Click Yes to confirm.
Disable Consistency Group
2 Select the Replication Sets tab of the consistency group to verify the physical volumes in use.

Step Action
3 Cross check physical volumes information from the host side. Use inq utility to list SAN attached volumes.
Note that on inq output CLARiiON LUNs are displayed in hexadecimal format. In this example, LUN64 is listed as 40.
4 Another very useful utility for host volumes monitoring and administration is PowerPath. Please use host tools that you feel more comfortable with.
Command Example
C:\>powermt display dev=all
5 Mount the replication volumes (in your consistency group) on hosts at both the local and remote site (site 1 and site 2). It might be necessary to make the volumes available to the OS (format volume, create file system, assign drive letter).
Please refer to the lab information sheet for volumes information. Windows hosts
a) In Computer Management > Disk Management, run Rescan disks. b) Find the replication volume and assign it a drive letter.
c) Verify that the disk is now accessible from the host. C:\>inq

Umount the replication volumes at the remote site (site 2) using kutils. The kutils utility was
installed automatically when you installed RecoverPoint host splitter (kdriver) on your hosts . It is necessary to be in the correct path (default C:\Program Files\KDriver\kutils) to run kutils commands. A return message (success or failure) is always expected. The kutils utility is case sensitive.
Command Example To unmount a device:
C:\program files\kdriver\kutils> kutils umount E: Unmounting drive E:... unmounted from
"\\?\Volume{33b4a391-26af-11d9-b57b-505054503030}\"
This command is available only on hosts running Windows. For Unix host use its native umount utility. For Windows 2003 and later, use the mountvol.exe, which comes with the Windows operating system.
Command Example To umount a device:
C:\>mountvol E: /p
7 A very helpful option is to set ‗mountvol‘ to automatic enable mounting of new volumes. For that, use the following option:
C:\>mountvol /E

8 Re-enable the consistency group by clicking on the Enable Group icon. Click Yes to confirm. Wait until Transfer status changes to Active.
Enable Consistency Group
9 On the Local site host, copy some files to the production volume.
10 Flush file system on the replication volumes at the local site (site 1) using kutils.
It is necessary to be in the correct path (default C:\Program Files\KDriver\kutils) to run kutils commands. A return message (success or failure) is always expected. The kutils utility is case sensitive.
Command Example
To initiate an OS-flush of the file system on the device designated as drive E: C:\program files\kdriver\kutils> kutils flushFS E: Flushing buffers for drive E:... Flushed.

16 Review the content and click Finish on the Summary window.
17 Once the bookmark is fully distributed and the remote site storage status changes to ―Logged access (0% full)‖, login into the remote server (site 2) and mount the replication volume.

18 If „mountvol‟ was previously set to automatic enable mounting of new devices this procedure might not be needed. Just run rescan disks in disk management.
Command Example To mount a device:
C:\program files\kdriver\kutils> kutils mount E: Mounting drive E: as
"\\?\Volume{33b4a391-26af-11d9-b57b-505054503030}\"... Mounted.
This command is available only on hosts running Windows. For Unix hosts use its native mount utility. For Windows 2003 and later, use the mountvol.exe, which comes with the Windows operating system.
Command Example To mount a device:
C:\> mountvol E: \\?\Volume{4b3d346c-c4cd-11dd-b127-
001aa0a858f4}\
Type „mountvol‟ alone to get a list of the possible volume names. Copy and paste the volume name into the command line after the driver letter of the volume you are trying to mount.
19 Access the volume on the remote server (site 2) and verify that it has the same data you copied into the production server volume (site 1).
This should be a proof of concept. Replication is working! If not, you probably missed a step. Go back and check:
a) Local and Remote servers have host splitter driver installed and running. b) Local and remote volumes have been attached to splitters.
c) You have copied data to the production volume (site 1).
d) You have flushed file system of production server volume (site 1) before creating the bookmark.
e) You are using the correct volumes! Make sure that the volumes within your consistency group are the ones you are copying data to, mounting and umounting.

Notice how data distribution resumes and the remote site storage status goes back to ―No access‖. The consistency group is in its previous state, replicating from local site to remote site.
