Removing a vSAN disk

The disk removal option enables users to remove a vSAN disk from the disk group and physically remove it from the disk bay.

Note

  • Before removing the cache disk, remember to back up the data; otherwise, the working virtual machines might be disrupted.

  • If deduplication and compression is enabled on vSAN host, and the cache disk or the last capacity disk is removed from the disk group, the entire disk group will be removed. When necessary, users should re-create the disk group manually.

  • After the physical disk is removed from the bay, the disk will be indicated with the dotted lines and its status will be empty.
