You should ensure that the cluster event log does not contain any unfixed events prior to applying a software upgrade, since these events may prevent a successful upgrade. Use the Troubleshooting Guide or the Maintenance Procedures to fix the events. In addition to checking the cluster event log we also strongly recommend using the SVC upgrade test utility. Contact IBM Support if you require assistance.


Mandatory Pre-Installation Requirement

It is important that you upgrade the SVC Console Code (GUI) before you upgrade the SVC cluster code.


The SAN Volume Controller Management GUI for V6.1.0 and V6.2.0 will run on the cluster, rather than on a Windows machine. The following SAN Volume Controller Console (SVCC) package will uninstall the existing SVCC GUI and create desktop shortcuts to the new management GUI.
