There are instances when you must take a disk offline. If a disk is corrupted, you must disable the disk before removing it. You must also disable a disk before moving the physical disk device to another location to be connected to another system. | | | |  | NOTE: Taking a disk offline is only useful on systems that support hot-swap removal and insertion of disks without needing to shut down and reboot the system. | | | | |
To take a disk offline, use the vxdiskadm command: Select menu item 10 (Disable (offline) a disk device) from the vxdiskadm main menu. At the following prompt, enter the address of the disk you want to disable: Disable (offline) a disk device
Menu: VolumeManager/Disk/OfflineDisk
Use this menu operation to disable all access to a disk device
by the Volume Manager. This operation can be applied only to
disks that are not currently in a disk group. Use this operation
if you intend to remove a disk from a system without rebooting.
NOTE:Many systems do not support disks that can be removed from
a system during normal operation. On such systems, the
offline operation is seldom useful.
