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, use the vxdiskadm command:
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.

The vxdiskadm program disables the specified disk.
3. At the following prompt, indicate whether you want to disable another device (y) or
return to the vxdiskadm main menu (n):
