the Resync operation. Resync is blocked during dirty progress. For information about how to try to
recover from failures, see “
To resync a synchronous mirror group:
1.
Right-click the group.
2.
Select Resync. A confirmation screen appears.
3.
Click Finish. The fabric agent running on the DPM tries to resynchronize the failed group. Check
the group state to see if the resynchronization was successful.
Deleting synchronous mirror groups
You can delete a sync mirror group under any one of the following conditions:
•
The group’s status is Partial.
•
The group’s status is Normal and the group has only one task.
•
The group has no host permissions.
Deleting a group with tasks has the following results:
•
All tasks in the group are detached.
•
Host permissions are removed from the virtual disks, but the virtual disks are not deleted.
•
When the deleted group has one task, and the task is the original task, the virtual disk remains
after deletion with its permissions.
•
When the deleted group has one task but the task is not the original task, its corresponding virtual
disk remains without permissions.
To delete a synchronous mirror group:
1.
Right-click the group.
2.
Click Delete. A confirmation screen appears.
3.
Click Finish. The group is deleted.
Forcing group deletion
Force delete enables recovery of a synchronous mirror group that, for an unknown reason, entered
an unexpected status. Force delete is enabled regardless of the status of the group. Force delete is
enabled only when no host has permission to access the sync mirror group.
When you force delete a synchronous mirror group, the group and its tasks are deleted. The virtual
disks of the group’s tasks remain without permissions. Any PiTs that existed on the group prior to its
deletion also remain. You can then expose the independent virtual disks to hosts and use them to
bring up the applications.
To force delete a sync mirror group:
1.
If necessary, do either of the following:
• Power down.
• Disconnect all hosts that use the synchronous mirror group and delete the hosts to remove
their permissions.
2.
Right-click the group.
3.
Click Force Delete. A confirmation screen appears.
4.
Click Finish. The group is deleted.
