If an ESXi host that runs a VSA cluster member stops working, the VSA cluster status changes to Offline. You can use the Replace VSA Cluster Member wizard to replace the ESXi host with a new ESXi host that runs a new VSA cluster member.

Add a newly installed ESXi host to vCenter Server and power off the ESXi host that accommodates the VSA cluster member that you want to replace. Do not remove the replaced ESXi host or the replaced VSA appliance from vCenter Server until you complete the Replace VSA Cluster Member wizard.


In the VSA Manager tab, click Appliances.


Right-click a VSA cluster member whose status is Offline and click Replace Appliance.

The Replace Appliance wizard appears.


On the Select Appliance page, select the vSphere Storage Appliance whose status is Offline, and click Next.


On the Select Host page, select a newly installed ESXi host and click Next.

VSA Manager verifies whether the available ESXi hosts meet the requirements to join a VSA cluster.


On the Format Disks page, select when to format the disks.



Format disks on first access

Disks are formatted after installation on first read or write.

Format disks immediately

Disks are formatted during the installation with zeroes. This requires additional time during the installation process.


On the Verify Configuration page, review the configuration of the replacement vSphere Storage Appliance, click Install, and click Yes in the confirmation dialog.

Wait for the wizard to finish replacing the failed VSA cluster member.


After the wizard completes the task, click Close.

The wizard deploys a vSphere Storage Appliance on the new ESXi host and configures the appliance to join the VSA cluster and replace the failed VSA cluster member.
