CMC 9.0 and 9.5, SNMP traps are modified at the Management Group level, not at the node level (see
“SNMP Configuration”).
1.3.1.1 Best Practices
• LSMD upgrade – LSMD upgrade is required for upgrading from 7.x to 8.5, 9.0 or 9.5.
• 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.

• 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 immediately after upgrading the remote site to. Refer to
Section 1.3.1.4.1: “How to Verify Management Group Version”.
