This DiskPart command is not available in any edition of Windows Vista.

Parameter Description

  • This command operates on disks that are in SAN online mode. It changes their SAN mode to offline.
  • If a dynamic disk in a disk group is taken offline, the status of the disk changes to missing and the group shows a disk that is offline. The missing disk is moved to the invalid group. If the dynamic disk is the last disk in the group, then the status of the disk will change to offline, and the empty group will be removed.
  • A disk must be selected for the offline disk command to succeed. Use the select disk command to select a disk and shift the focus to it.


To take the disk with focus offline, type:

offline disk
