Figure 26 Recovery tab—Attempt to become active
The second window on the Recovery tab (Figure 27) 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.
Figure 27 Recovery tab—VSM in Partial state
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.
3. On the surviving site, for every failed synchronous mirror group, right-click the mirror group, and
select Manage > Recovery > Force Resume.
4. To run Force Resume on all of the failed synchronous mirror groups, right-click the synchronous
mirror entity in the left pane, and select Recovery > Force Resume All.
Force Resume assigns the local synchronous mirror task to be the new primary task for the group,
marks the other tasks as secondary, and brings the synchronous mirror virtual disk to a state of
Normal.
