Fractured mirrorclone guidelines
The following table describes the tasks that you can and cannot perform when the mirrorclone is
in a fractured state.
No. The disk must first be detached, then deleted.Deleting
Yes.Detaching
Not applicable.Fracturing
No. Only a synchronized mirrorclone can perform a migrate operation.Migrating
Yes. The disk can be presented immediately to hosts for I/O.Presenting
No. Snapclones of mirrorclones are not supported.Replicating—snapclones
Yes. Multiple snapshots are allowed.Replicating—snapshots
Yes. The disk must be unpresented first.Restoring
Yes. The disk must be unpresented first.Resynchronizing
Mirrorclone states
The following table describes mirrorclone states reported by the replication manager.
RemarksMirrorclone state
There is no replication activity between the mirrorclone virtual disk and its
source virtual disk. At the instant of the fracture, data on the mirrorclone
Fractured
is identical to its source. After a fracture, data on the two disks may no
longer be identical due to host I/O to the source or the mirrorclone.
In response to a replication command, data is being copied from the
mirrorclone virtual disk to its original source virtual disk. Data on the
original source is not yet identical to its mirrorclone.
Restore in progress
The source virtual disk and its mirrorclone are synchronized. Data on the
mirrorclone is identical to its source. Any changes to data on the source
virtual disk are automatically copied to its mirrorclone.
Synchronized or normalized
In response to a replication command, data is being copied from the
source virtual disk to its mirrorclone virtual disk. Data on the mirrorclone
is not yet identical to its source.
Sync in progress
When a mirrorclone has been detached, it is no longer a
