NOTE: When installing/upgrading SAN/iQ 8.5, do not modify the default SNMP settings. The default settings are used by Insight Remote Support, and communication between the P4000 Storage System and the Hosting Device will not function properly if the SNMP settings are modified. 1.3.1.1 Best Practices • LSMD upgrade - LSMD upgrade is required for upgrading from 7.x to 8.5. • Virtual IP addresses - If a Virtual IP (VIP) address is assigned to a storage node in a cluster, the VIP storage node needs to be upgraded last. The VIP storage node is shown on the cluster iSCSI tab, shown in Figure 1-2 "Find the Storage Node Running the VIP". 1. First upgrade the non-VIP storage nodes that are running managers, one at a time. 2. Then upgrade the non-VIP non-manager storage nodes. 3. Lastly, upgrade the VIP storage node. Figure 1-2 Find the Storage Node Running the VIP • Remote Copy - If you are upgrading management groups with Remote Copy associations, you should upgrade the remote management groups first. If you upgrade the primary group first, Remote Copy may stop working temporarily, until both the primary management group and the remote group have finished upgrading. Upgrade the primary site to 8.5 immediately after upgrading the remote site to 8.5. Refer to How to verify management group version. 10 P4000 Storage Systems Migration Procedure
