HP P6000 manual Synchronized mirrorclone guidelines, Fractured mirrorclone guidelines

•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).

Synchronized mirrorclone guidelines

Tasks you can and cannot perform when the mirrorclone is in a normalized/synchronized state:

Deleting	No. The disk must first be fractured and detached, then deleted.
Detaching	No. The disk must first be fractured, then detached.
Fracturing	Yes.
Migrating	Yes, with XCS 10000000 or later.
Presenting	No. The disk must first be fractured, then presented.
Replicating	No. The disk must first be fractured, then replicated with a snapshot.
Restoring	No. The disk must first be fractured, then used to restore.
Resynchronizing	Not applicable. When a mirrorclone is normalized/synchronized, it does not
	need to be resynchronized.

Fractured mirrorclone guidelines

Tasks you can and cannot perform when the mirrorclone is in a fractured state:

Deleting	No. The disk must first be detached, then deleted.
Detaching	Yes.
Fracturing	Not applicable.
Migrating	No.
Presenting	Yes. The disk can immediately be presented to hosts for I/O.
Replicating—Snapclones	No. Snapclones of mirrorclones are not supported.
Replicating—Snapshots	Yes. Multiple snapshots are allowed.
Restoring	Yes. The disk must be unpresented first.
Resynchronizing	Yes. The disk must be unpresented first.
