Problem

Causes:

Cannot create Snapshot pairs.

There are not enough differential tables to create the pairs.

The conditions to create the pair are not fulfilled.

The volumes specified to create the pair is in SMPL(PD) status because the pair is being
deleted.

Solutions:

Secure enough differential tables to create the Snapshot pairs.

Fulfill the conditions to create the pair and try the pair creation again.

See the Business Copy Pair Operation window and verify that the status of the volume changes
to SMPL, and then try the pair creation again.

Execute RAID Manager’s inqraid command and verify that the volume is not used by Snapshot,
and then try the pair creation again.

Causes:

Snapshot pairs are not
displayed in the volume list.

Snapshot pairs are not created.

Displaying of the Snapshot pairs is prohibited by the filtering function.

Solutions:

Create Snapshot pairs.

Change the settings in the Display Filter dialog box.

An error occurred while
restoring the pair.

Solution: Delete the Snapshot pair that is blocked, and contact HP Technical Support.

access the port.

Wait a while then retry the operation.

If a host application is installed to monitor the volume, stop the application.

Causes:
