Patch a vCenter High Availability Environment
This procedure describes how to patch the Active, Passive, and Witness node if your
vCenter Server Appliance is configured in a vCenter High Availability (HA) cluster.
A vCenter High Availability cluster consists of three vCenter Server Appliances that act as an Active,
Passive, and Witness node. For information about configuring vCenter High Availability, see vSphere
Availability.
You patch the three nodes in a sequence and use a manual failover so that you always patch a non-
Active node. For patching the nodes you must use the software-packages utility from the appliance
shell. For information about patching the appliance from the appliance shell, see Patching the vCenter
Server Appliance by Using the Appliance Shell.
Procedure
1 Place the vCenter HA cluster in maintenance mode.
a In the vSphere Web Client inventory, click the Configure tab.
b Under Settings, select vCenter HA and click Edit.
c Select Maintenance Mode and click OK.
2 Log in as root to the appliance shell of the Active node by using the public IP address.
3 Patch the Witness node.
a From the appliance shell of the Active node, establish an SSH session to the Witness node.
ssh root@Witness_node_IP_address
b From the appliance shell of the Witness node, patch the Witness node.
Use the software-packages utility.
c Exit the SSH session to the Witness node.
