Potential required changes for NetApp clusters
As part of the 9.1 upgrade, review the settings of any NetApp clusters. If the cluster mode is set to Node scope mode, both Veritas and NetApp recommend that you change to Vserver aware mode. If you plan to move to Vserver aware mode as part of the upgrade, create a detailed image report for each of your filers. Use the bpimagelist command to generate this list. Depending on the size of your environment, this activity can take some time. More information is available.
