Cabling the HA interconnect (all systems except 32xx or 80xx in separate chassis)

To cable the HA interconnect between the HA pair nodes, you must make sure that your interconnect adapter is in the correct slot. You must also connect the adapters on each node with the optical cable.

About this task

This procedure applies to all dual-chassis HA pairs (HA pairs in which the two controller modules reside in separate chassis) except the 32xx or 80xx in separate chassis, regardless of disk shelf type.


  1. Verify that your interconnect adapter is in the correct slot for your system in an HA pair.

    For systems that use an NVRAM adapter, the NVRAM adapter functions as the HA interconnect adapter.

  2. Plug one end of the optical cable into one of the local node's HA adapter ports, then plug the other end into the partner node's corresponding adapter port.

    You must not cross-cable the HA interconnect adapter. Cable the local node ports only to the identical ports on the partner node.

    If the system detects a cross-cabled HA interconnect, the following message appears on the system console and in the event log (accessible using the event log show command):

    HA interconnect port <port> of this appliance seems to be connected to port <port> on the partner appliance.

  3. Repeat Step 2 for the two remaining ports on the HA adapters.


The nodes are connected to each other.
