XCS 10000000 supports online mirrorclone migration, which allows you to switch the roles
of a source virtual disk with its synchronized mirrorclone. See

“Mirrorclone migration” (page

33)

.

A mirrorclone can be presented only if the mirror link is stopped (fractured).

For more information, see the HP P6000 Replication Solutions Manager Release Notes.

A mirrorclone cannot be created if the intended source virtual disk is:

A snapshot or has any snapshots.

Has any snapclones that are in the process of being normalized (P6000 Command View
