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.

Warning: 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 menu item 11 (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):

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