vSphere Storage4 Select a non-SSD disk and click Virtual Disks to review virtual machines that use the disk.You can review all virtual machine objects and whether they are in compliance with the storage policiesassigned to them.Monitor Disks that Participate in Virtual SAN DatastoresVerify the status of the disks that back up the Virtual SAN datastore. You can check whether the disksexperience any problems.Procedure1 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:aRight-click the column heading and select Show/Hide Columns.bSelect Issue to display the column.The Issue column alerts you if the disks become ineligible. If the disks experience no problems, thecolumn does not display any values.Managing Virtual SANAfter you have set up your Virtual SAN cluster, you can use the vSphere Web Client to add hosts and disks,remove hosts and disks, and manage failure scenarios.Expanding a Virtual SAN ClusterYou can expand an existing Virtual SAN cluster by adding hosts or disks to the hosts.Use one of the following methods to expand your Virtual SAN cluster.• Add new ESXi hosts to the cluster or move existing inventory hosts in to the cluster without disruptingany ongoing operations. New cluster members add storage and compute capacity. If you use VirtualSAN in automatic mode, storage disks on the new cluster member will be automatically aggregatedinto a disk group and claimed by the Virtual SAN datastore. If Virtual SAN is set to manual, you mustmanually create disk groups from the storage disks on the newly added host. See “Use Manual Methodto Claim Disks for Virtual SAN,” on page 184.• Add new storage disks to ESXi hosts that are cluster members. If you use Virtual SAN in automaticmode, the new disk that you add joins an existing disk group. If Virtual SAN is set to manual, you mustmanually add the disk to the disk group on the host. See “Add a Disk to the Disk Group,” on page 184.Add a Host to the Virtual SAN ClusterYou can add an ESXi host to a running Virtual SAN cluster without disrupting any ongoing operations. Thehost's resources become associated with the cluster.Procedure1 Browse to the Virtual SAN cluster in the vSphere Web Client navigator.2 Right-click the cluster and select Add Host.3 Enter the host name, user name, and password, and click Next.186 VMware, Inc.
