Figure 38 Recovery tab—Attempt to become active
.
The second window on the Recovery tab (see Figure 39) 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 setup
volume 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 server reboots itself and comes up as the active VSM. After the VSM
comes up, the VSM uses only the surviving setup virtual disk to synchronize the mirrored tasks.
3. At the surviving site, for every synchronous mirror group that has a status of Partial, make sure
that the surviving DPM, which will have a status of Present, is the active DPM for that synchronous
mirror group. You can see the status of the DPM on the Data Path Module tab.
If the surviving DPM does not have a status of Present, change the active DPM for the synchronous
mirror group. Right-click the synchronous mirror group, and select Manage > Manage Data Path
