1.3 Configuring the P4000 Storage Systems 1.3.1 Upgrading the SAN/iQ Software on the P4000 Storage Systems You will use CMC to upgrade to SAN/iQ 8.5 on the P4000 Storage Systems. If your P4000 Storage Systems already has SAN/iQ 8.5 installed, you do not need to perform this procedure. 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. See Appendix A for flowcharts that describe how to upgrade from different versions of SAN/iQ. 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 CMS 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. 10 P4000 Storage Systems Migration Procedure

1.3 Configuring the P4000 Storage Systems
1.3.1 Upgrading the SAN/iQ Software on the P4000 Storage Systems
You will use CMC to upgrade to SAN/iQ 8.5 on the P4000 Storage Systems. If your P4000 Storage Systems
already has SAN/iQ 8.5 installed, you do
not
need to perform this procedure.
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.
See
Appendix A
for flowcharts that describe how to upgrade from different versions of SAN/iQ.
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 CMS 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.
