Claim Storage Devices for a Virtual SAN Cluster

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

Procedure

1. Navigate to the Virtual SAN cluster in the vSphere Web Client.
2. Click the Configure tab.
3. Under vSAN, click Disk Management.
4. Click the Claim Disks icon ().
5. Select devices to add to the disk group.
   • Each host that contributes storage to a hybrid disk group must contribute one flash cache device and one or more capacity devices. You can add only one flash cache device per disk group.
     • Select a flash device to be used as cache and click the Claim for cache tier icon ().
     • Select an HDD device to be used as capacity and click the Claim for capacity tier icon ().
     • Click OK.
   • For all-flash disk groups, select flash devices for both capacity and cache.
     • Select a flash device to be used as cache and click the Claim for cache tier icon ().
     • Select a flash device to be used for capacity and click the Claim for capacity tier icon ().
     • Click 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.
   Virtual SAN claims the devices that you selected and organizes them into default disk groups that support the Virtual SAN datastore.
