vSAN claims the devices that you selected and organizes them into default disk groups that contribute the
vSAN datastore.
To verify the role of each device added to the all-flash disk group, navigate to the "Claimed as" column for a given host on the Disk Management page. The table shows the list of devices and their purpose in a disk group. For all-flash and hybrid disk groups, the cache disk is always shown first in the disk group grid.
