You can select a group of cache and capacity devices, and vSAN organizes them into default disk groups.

Procedure

  1. Navigate to the vSAN cluster.
  2. Click the Configure tab.
  3. Under vSAN, click Disk Management.
  4. Click Claim Unused Disks.
  5. Select devices to add to the disk group.
    • For hybrid disk groups, each host that contributes storage must contribute one flash cache device and one or more HDD capacity devices. You can add only one cache device per disk group.
      • Select a flash device to be used as cache and click Claim for cache tier.
      • Select an HDD device to be used as capacity and click Claim for capacity tier.
      • Click Create or OK.
    • For all-flash disk groups, each host that contributes storage must contribute one flash cache device and one or more flash capacity devices. You can add only one cache device per disk group.
      • Select a flash device to be used as cache and click Claim for cache tier.
      • Select a flash device to be used for capacity and click Claim for capacity tier.
      • Click Create or OK.
    To verify the role of each device added to the all-flash disk group, navigate to the Disk Role column at the bottom of the Disk Management page. The column shows the list of devices and their purpose in a disk group.
    vSAN claims the devices that you selected and organizes them into default disk groups that support the vSAN datastore.
