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.
▼ To mirror all volumes on a disk
1. Select the disk that contains the volumes to be mirrored onto another disk.
2. Choose Actions > Mirror Disk.
3. Enter the target disk name in the Mirror Disk. Click OK.
Notes:
- 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.
