•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. |
No. Snapclones of mirrorclones are not supported. | |
Yes. Multiple snapshots are allowed. | |
Restoring | Yes. The disk must be unpresented first. |
Resynchronizing | Yes. The disk must be unpresented first. |
