Cable node1 for shared cluster-HA and storage (AFF A800 upgrade only)

Connect the cluster, HA, storage, data, and management connections that were previously connected to the AFF A800 node1 to the newly installed AFF A90 or AFF A70 node1.

Connect the e0M and BMC ports

The AFF A800 has a management port (e0M) and a BMC port. On the AFF A90 and AFF A70, the e0M and BMC ports are combined and accessed through the "wrench" port. You must ensure that the e0M and BMC ports are connected to the same switch and subnet on the AFF A800 before connecting to the AFF A90 or AFF A70.

e0M and BMC IP addresses are on the same IP subnet	Connect either the e0M or BMC port on the AFF A800 to the "wrench" port on the AFF A90 or AFF A70.
e0M and BMC IP addresses are on different subnets	Merge the e0M and BMC IP addresses into one IP subnet. Connect either the e0M or BMC port on the AFF A800 to the "wrench" port on the AFF A90 or AFF A70.

Connect to a two-node switchless cluster

The following table shows the switch port usage for two-node switchless cluster configurations.

Port	AFF A800 node	AFF A90 node	AFF A70 node
Cluster	e0a	e1a	e1a
Cluster	e1a	e7a (Use e1b if there is no e7a)	e1b
HA	e0b	Do not connect	Do not connect
HA	e1b	Do not connect	Do not connect
SAS storage ports (if present and used)	Any available port	Any available port	Any available port
Ethernet storage ports for NS224 shelves	Any available port	Refer to Ethernet storage connectivity mapping	Refer to Ethernet storage connectivity mapping

Connect to a switch-attached cluster

For a switch-attached cluster, check that you meet the following requirements:

• The identical cluster ports on the AFF A90 or AFF A70 nodes 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, will result in HA communication failures.

• The AFF A90 and AFF A70 nodes use shared cluster-HA Ethernet ports. Ensure that the cluster switches are installed with a reference configuration file (RCF) that supports shared cluster-HA ports.
