Takes the online disk with focus to the offline state.


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

For examples of how this command can be used, see Examples.


offline disk [noerr]


Parameter Description


For scripting only. When an error is encountered, DiskPart continues to process commands as if the error did not occur. Without this parameter, an error causes DiskPart to exit with an error code.


  • This command operates on a single disk.

  • 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 pack is taken offline, the status of the disk changes to Missing and the pack shows a disk that is offline. The missing disk is moved to the invalid pack. If the dynamic disk is the last disk in the pack, then the status of the disk will change to Offline, and the empty pack 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
