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.


Taking a disk offline is only useful on systems that support hot-swap removal and insertion of disks. If a system does not support hot-swap removal and insertion of disks, you must shut down the system.

To take a disk offline

  1. Select 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:

    Select a disk device to disable [<address>,list,q,?]

    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):

    Disable another device? [y,n,q,?] (default: n)
