Verify the status of the disks that back up the Virtual SAN datastore. You can check whether the disks experience any problems.


  1. Browse to Datastores in the vSphere Web Client navigator.
  2. Select the Virtual SAN datastore.
  3. Click the Manage tab, and click Settings.
  4. Click Device Backing.
  5. Select the disk group and review the local disks listed in the Disks table.
  6. If the Issue column for the disks is not visible, do the following:
    1. Right-click the column heading and select Show/Hide Columns.
    2. Select Issue to display the column.
    The Issue column alerts you if the disks become ineligible. If the disks experience no problems, the column does not display any values.
