RAID Controller Module Ownership/Preferred Path
During a remote replication operation, the RAID controller module that owns the primary virtual disk must correspond to
the RAID controller owning the secondary volume on the remote array. If both virtual disks do not have the same
preferred RAID controller module when a remote replication begins, the ownership of the secondary virtual disk is
automatically transferred to the preferred RAID controller module of the primary virtual disk.
• When the remote replication is completed or is stopped, ownership of the secondary virtual disk is restored to
its preferred RAID controller module.
• If ownership of the primary virtual disk is changed during the remote replication, ownership of the secondary
virtual disk is also changed.
If any of the following conditions apply to your RAID controller module, you must manually change module ownership to
the alternate RAID controller module to allow the remote replication to finish:
• The status of the remote replication is In Progress.
• The preferred RAID controller module of the primary virtual disk fails.
• Transfer of ownership does not occur automatically during failover.
CAUTION: To avoid possible loss of data, verify that either the virtual disks are not in use, or a multi-path
driver is installed on the host. If you change the RAID controller module ownership/preferred path while an
application is using one of the virtual disks, I/O activity is disrupted and I/O errors may occur.
Viewing Information About A Remote Replication (Legacy) Or
Replication Repository (Legacy) Virtual Disk
In MD Storage Manager, the Storage Array Profile and the Properties pane display information about the physical and
logical characteristics of the remote replication.
Viewing The Storage Array Profile
The Storage Array Profile displays the most detailed information about the components of a remote replication and the
replication repository virtual disks. You can:
• View detailed information about individual and paired virtual disks in a remote replication
• View detailed information about the replication repository virtual disks in the remote replication and storage
array
• Save the Storage Array Profile information as a text file
To view the Storage Array Profile:
1. In the AMW of the local or remote storage array, select the Summary tab.
2. In the Monitor area, click View Storage Array Profile.
The Storage Array Profile window is displayed.
3. Under the Storage tab, select the Virtual Disks tab.
4. Select either the Replications tab or the Repositories tab.
The Profile for the Storage array page is displayed.
5. Perform one of the following:
– To return to the AMW without saving the information, click Close.
– To save the information, click Save As, then go to Step 6.
