Mirroring a Disk
The Mirror Disk procedure mirrors (copies) all concatenated and
striped volumes on a disk onto another disk. You can use this procedure
to mirror any disk that contains concatenated or striped volumes.
NOTE You require a licence to mirror disks other than the root disk.
To mirror all volumes on a disk
Step 1. Select the disk that contains the volumes to be mirrored onto another
disk.
Step 2. Choose Actions > Mirror Disk.
Step 3. Enter the target disk name in the Mirror Disk. Click OK.
NOTE
• The Disk Mirror task requires a disk name.
• Only concatenated and striped volumes that reside on a single disk
are mirrored onto the other disk. Any RAID-5 or spanned volumes on
the disk are ignored.
• Only disks in the same dynamic disk group can be used to create the
new mirrors.
• The target disk must contain sufficient space to accommodate the
mirrors.
• A new mirror cannot be created on a disk that already contains a
copy of the volume.
• If no disks are assigned, VxVM uses available disk space to create
the mirrors.
