Enabling a Physical Disk

If you move a disk from one system to another during normal system operation, VxVM does not recognize the disk automatically. The enable disk task enables VxVM to identify the disk and to determine if this disk is part of a disk group. Also, this task re-enables access to a disk that was disabled by either the disk group deport task or the disk device disable (offline) task.

To enable a disk, use the following procedure:

1. Select menu item 9 (Enable (online) a disk device) from the vxdiskadm main menu.
2. At the following prompt, enter the device name of the disk to be enabled (or enter list for a list of devices):
   Enable (online) a disk device 
   Menu: VolumeManager/Disk/OnlineDisk 
   VxVM INFO V-5-2-998 Use this operation to enable access to a disk that was disabled with the "Disable (offline) a disk device" operation.
   You can also use this operation to re-scan a disk that may have
   been changed outside of the Volume Manager. For example, if a
   disk is shared between two systems, the Volume Manager running
   on the other system may have changed the disk. If so, you can
   use this operation to re-scan the disk. 
   NOTE: Many vxdiskadm operations re-scan disks without user
      intervention. This will eliminate the need to online a
      disk directly, except when the disk is directly offlined.
   Select a disk device to enable [<address>,list,q,?] c0t2d0

   vxdiskadm enables the specified device.

3. At the following prompt, indicate whether you want to enable another device (y) or return to the vxdiskadm main menu (n):
   Enable another device? [y,n,q,?] (default: n)
