Chapter 17: P4000 Storage Systems Migration Procedure
CMC version 9.0 and higher provides a new option to download SAN/iQ upgrades and patches from the
HP. Once the current upgrades and patches are downloaded from HP to the CMC system, CMC can be
used to update Management Groups or nodes with these changes.
When you upgrade the SAN/iQ software on a storage node, the version number changes. Check the
current software version by selecting a storage node in the navigation window and viewing the Details tab
window.
Note: When installing/upgrading SAN/iQ, 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 CMS will not function properly if the SNMP settings are modified. SNMP is enabled
by default in SAN/iQ. In CMC 9.0 and higher, SNMP traps are modified at the Management Group
level, not at the node level (see "SNMP Configuration" on page 137).
Best Practices
l LSMD upgrade LSMD upgrade is required for upgrading from 7.x to 8.5, 9.0, 9.5, 10.0, or 10.5.
l 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 16.2. Find the Storage Node Running the VIP" below.
a. First upgrade the non-VIP storage nodes that are running managers, one at a time.
b. Then upgrade the non-VIP non-manager storage nodes.
c. Lastly, upgrade the VIP storage node.
Figure 16.2. Find the Storage Node Running the VIP
l 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 "How to
Verify Management Group Version" on page 143.
Selecting the Type of Upgrade
CMC supports two methods of upgrades, as shown in "Figure 16.3. Viewing the CMC
Upgrade/Installation Window" on the next page.
l One-at-a-time (recommended) - this is the default and only method that should be used if the
storage nodes exist in a management group.
