It is mandatory to create a snapshot of each node in a cluster before you update a vRealize Operations cluster. Once the update is complete, you must delete the snapshot to avoid performance degradation.
For more information about snapshots, see the vSphere Virtual Machine Administration documentation.
Procedure
- Log into the vRealize Operations Administrator interface at
https://<primary-node-FQDN-or-IP-address>/admin
. - Click Take Offline under the cluster status.
- When all nodes are offline, open the vSphere client.
- Right-click a vRealize Operations virtual machine.
- Click Snapshot and then click Take Snapshot.
- Name the snapshot. Use a meaningful name such as "Pre-Update."
- Uncheck the Snapshot the Virtual Machine Memory check box.
- Uncheck the Ensure Quiesce Guest File System (Needs VMware Tools installed) check box.
- Click OK.
- Repeat these steps for each node in the cluster.
