HP Matrix Operating Environment 7.3 Recovery Management User Guide

A Recover the CSV from online pending state
If you perform an activate operation at the remote site without taking the CSV offline at the local
site, you might see the following symptoms at the local site:
• No storage information is available when navigating to the storage view in the Windows
Failover Cluster Management tool.
• The CSV is in the online pending state.
To recover from these symptoms, perform the following steps:
1. Using the storage management tool of your choice, perform the following steps:
1. Unexport the CSV virtual volume from the Hyper V cluster. Note the LUN number. Leave
the virtual volume unexported until an opportune maintenance period.
2. During the maintenance period, deactivate the recovery group on the other site where it
might be currently active and take the CSV offline.
3. Perform storage failover to place the CSV virtual volume in read-write mode.
4. Export the CSV virtual volume to the Hyper V cluster using the same LUN number as when
you originaqlly exported the LUN.
2. Bring the CSV online using the Hyper V cluster manager.
3. Rename the CSV folder name to the original folder name.
4. Perform Logical Server refresh resources on the Matrix OE visualization GUI.
5. Activate the recovery group on the CMS.
