Determining the version of the SAN Volume Controller software

The current software version can be obtained from the node or cluster vital product data (VPD). It can also be determined from the front panel menu in both standard and service modes.

During a software upgrade, the version number of each node is updated when the software is installed and that node is restarted. The cluster software version number is updated when the new version of software is committed.

Note: The software version number is in the format x.y.z where x is a version release number, y is a major number, and z is a minor number. For example, version number 1.2.3 has a version release number of 1, a major number of 2, and a minor number of 3. This number determines whether software versions can be reverted to the previous version. It is not possible to revert a version of software to a version that has a lower major number. For example, if version 1.2.3 is running on the cluster, it can be replaced with version 1.2.2 or 1.2.1 but it cannot be replaced with version 1.1.6.

Issue the following command on the CLI to determine the version of the software that is currently running on the cluster:

svcinfo lscluster cluster_name

where cluster_name is the name of the cluster.

The cluster code level is listed in the code level field. In the following example, cluster rc-cluster-20 is running at code level 4.1.0.12:
