Description

Over time, the initially planned disk capacity may exceed the user's actual needs, resulting in wasted disk resources. Alternatively, changes in the user's business may lead to different storage requirements, necessitating disk downsizing or deletion, the operation will not impact the VM business.

Precautions

1. Before deleting disks, the number of nodes that have contributed disks to the virtual storage pool must be greater than three.
2. After disk deletion, the number of nodes contributing disks to the virtual storage pool must be greater than or equal to three
3. If the number of nodes contributing disks to the virtual storage pool drops to four or three after disk deletion, each host must have two disk groups.
4. If you remove the cache disk, the cache disk and the disk group of the cache disk will be removed from the virtual datastore.

Steps:

1. Go to Storage > Virtual Storage > Physical Disks and click the disk to be removed.

Click Isolate Disk and then OK on the confirmation dialog box.

Select the isolate method then click OK.

2. Click Remove Disk and then OK on the confirmation dialog box.
