Offlining a Disk
This procedure prevents the Volume Manager from accessing a disk. A
disk must be removed from its disk group before it can be taken offline
(see “Removing a Disk”). An offline disk remains unavailable until you
restore access to the disk (see “Onlining a Disk”).
To take a disk offline
Step 1. Select the disk to be taken offline.
Step 2. Choose Disks > Offline (Selected menu) or Disk Offline (Command
Launcher).
Step 3. Complete the Offline Disk dialog box as follows:
When you have provided all necessary information in the dialog box,
click OK.
Disk(s): If the correct disk name is not already displayed in this
field, type the disk’s name or click Browse to select the
disk.
Notes:
• When a disk is offline, the disk cannot be accessed by the Volume
Manager.
• A disk can be taken offline to protect it from unintentional use. Disks
should be taken offline if they are not accessible and attempts to
access them may have a negative effect on the system.
• Only disks that do not belong to a disk group can be taken offline.
• Disks that are in use cannot be taken offline.
