Upgrade your host adapter firmware if you want to apply bug fixes or enable new functionality.
This procedure relies on the following prerequisites and assumptions.
Your cluster is operational.
This procedure defines Node A as the node on which you are upgrading the host adapter firmware.
This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands, in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS.
To perform this procedure, become superuser or assume a role that provides solaris.cluster.read and solaris.cluster.modify RBAC authorization.
Determine the resource groups and device groups that are running on the node on which you plan to upgrade the host adapter firmware.
Move all resource groups and device groups off Node A.
Perform the firmware upgrade.
For the procedure about how to upgrade your host adapter firmware, see the patch documentation.
(Optional) Return the device groups back to Node A.
Perform the following step for each device group you want to return to the original node.
(Optional) Return the resource groups back to Node A.
Perform the following step for each resource group you want to return to the original node.
If you are using Sun Cluster 3.2, use the following command:
# clresourcegroup switch -n NodeA resourcegroup |
For failover resource groups, the node to which the groups are returned. For scalable resource groups, the node list to which the groups are returned.
The resource group that is returned to the node or nodes.
If you are using Sun Cluster 3.1, use the following command:
# scswitch -z -g resourcegroup -h NodeA |
