Taking a disk offline
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
1 Select menu item 10 (Disable (offline) a disk device) from the
vxdiskadm main menu.
2 At the following prompt, enter the address of the disk you want to disable:
Disable (offline) a disk device
Menu: VolumeManager/Disk/OfflineDisk
VxVM INFO V-5-2-474 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.
