Upgrade procedure

Important: Ensure to complete the procedure in the Preparing for upgrade topic before upgrading PowerVC.
Upgrade the multi nodes one after the other in this order.
  1. Primary node should always be updated first.
  2. Update the non-VIP running node.
  3. Update the VIP running node.
This update order must be followed to ensure service availability and cluster stability during the rolling update process.
Run the powervc-opsmgr update -c <cluster_name> -n <node_ip/hostname> command to upgrade each non-primary/bootstrap node.
Note:
  • <cluster_name> is the name of your PowerVC cluster.
  • <node_ip/hostname> is the IP address or hostname of the node to upgrade.

Repeat this command for each node in the cluster, one at a time. Wait for each node upgrade to complete successfully before proceeding to the next node. Optionally, you can skip the remote node upgrade.

If you want to skip remote node upgrade during the PowerVC upgrade, use the -sr option.

Example of the CLI command- powervc-opsmgr update -c <cluster_name> -n <node_ip/hostname> -sr.
Note: If you select the skip remote node option, PowerVC packages on NovaLink can be updated using the Update NovaLink button from the UI after the update.

After the PowerVC upgrade is complete, you can upgrade the remote nodes separately.
