You can edit cluster properties to turn on Virtual SAN for an existing cluster.
Verify that your environment meets all requirements. See Requirements for Virtual SAN.
- Browse to the host cluster in the vSphere Web Client navigator.
- Click the Manage tab and click Settings.
- Under Virtual SAN, select General and click Edit to edit Virtual SAN settings.
- Select the mode for storage disks to be claimed.
Claims all empty disks on the included hosts for Virtual SAN. Virtual SAN in automatic mode claims only local disks on the ESXi hosts in the cluster. You can add any remote non-shared disks manually.
Requires manual claiming of the disks on the included hosts. New disks on the host are not added to Virtual SAN. With the manual mode, two methods of organizing disks into disk groups exist, semi-automatic and manual.Note:
When you use this mode, a Virtual SAN datastore is created, but its initial size is 0 bytes. The datastore remains unusable until you manually claim disks.
- Click OK.
Enabling Virtual SAN creates a Virtual SAN datastore and registers the Virtual SAN storage provider. The Virtual SAN storage provider communicates to vCenter Server storage capabilities of the datastore.
What to do next
Verify that the Virtual SAN datastore has been created. See View Virtual SAN Datastore.
Verify that the Virtual SAN storage provider is registered. See View Virtual SAN Storage Providers.
If you use manual mode for Virtual SAN, claim disks or create disk groups. See Managing Disk Groups.
If you want to disable Virtual SAN on a cluster, see Disable Virtual SAN.
