Cable node2 for shared cluster-HA and storage

PDFs
If you are performing one of the following upgrades, you need to connect the cluster, HA, storage, data, and management connections that were previously connected to the node2 on the existing system to the newly installed node2 on the replacement system.

Connect the e0M and BMC ports
If the existing system has a management port (e0M) and a BMC port, the e0M and BMC ports are combined and accessed through the "wrench" port on the replacement system. You must ensure that the e0M and BMC ports are connected to the same switch and subnet on the existing system before connecting to the replacement system.

e0M and BMC IP addresses are on the same IP subnet |
Connect either the e0M or BMC port on the existing system to the "wrench" port on the replacement system. |
e0M and BMC IP addresses are on different subnets |

Connect to a switch-attached cluster
For a switch-attached cluster, check that you meet the following requirements for the AFF A30, AFF A50, AFF A70, AFF A90, AFF C30, AFF C60, or AFF C80 (replacement) node:
-
The identical cluster ports on the replacement node are on the same switch. For example, on completion of the upgrade, e1a on node1 and e1a on node2 should be attached to one cluster switch. Similarly, the second cluster port from both nodes should be attached to the second cluster switch. Cross-connection of shared cluster-HA ports, where e1a from node1 is connected to switchA and e1a from node2 is connected to switchB, results in HA communication failures.
-
The replacement node uses shared cluster-HA Ethernet ports.
-
Verify that the cluster switches are installed with a reference configuration file (RCF) that supports shared cluster-HA ports:
-
Remove the existing configuration on the switch:

If the cluster switch only supports 10/25 GbE speeds, you must use an X60130A, 4-port 10/25GbE card in slot1 or slot2 on the replacement system for cluster interconnect. |
