HP StorageWorks SAN Virtualization Services Platform administrator guide (5697-0204, January 2010)

Whenever you select an entry and click the Yes button or the OK button, make sure that the status
of the VSM is Passive. The entries from the Recovery tab are not accepted when the VSM is
stopped.
The first window on the Recovery tab asks your permission to use the surviving copy of the boot
data and to ignore the missing ones. Figure 36 shows the Recovery tab message asking if you
want the VSM to attempt to become active.

.
The second window on the Recovery tab (Figure 37) notifies you that the synchronous mirror of
the setup virtual disk has a status of Partial. A status of Partial means that some of the mirror tasks
are missing and that the mirror cannot decide which task to use. The window offers these options:
• Resume—Use this option after you have fixed the problem that prevented the access to some
of the mirror tasks.
• Recover—Use this option after you decide that you cannot recover the failed task. This option
offers you a list of the surviving tasks and asks you to pick the one to use. Select one of the
tasks from the drop-down list, and click OK.

After clicking OK, the VSM application will restart itself and will come up as the active VSM.
After the VSM comes up, the VSM will use only the surviving setup virtual disk to synchronize the
mirrored tasks.
