• 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
10000000 or earlier).
• See also, “Optimizing snap creation” (page 40).
