Goal

1. The intend of this document is to provide the steps to follow to replace an Inter Connect Assembly (ICA) on a live system. 
2. This document supplements the instructions found in Sun Storage Common Array Manager (CAM) Service Advisor. 
3. ICAs are typically candidates for replacement when there communications between the controllers is a suspected problem.

Solution

It is possible to replace an ICA on a live system but doing so requires certain prerequisites be met first.  When the ICA is removed, the connection between the two controllers as well as sharing of power in the controller tray is broken.  And by design the B controller will go offline and the A controller will be powered only by the Power Supply that is directly attached to it.

As such before proceeding with the replacement steps covered in CAM Service Advisor or SANtricity Recovery Guru,  you must verify the following:

1. That the A Controller is optimal.
   
2. That the A Power Supply (right side viewed from the front) is optimal.
3. That all data hosts have properly functioning data path management software installed to make sure that data access is not lost when the B controller goes offline.

The controller and power supply status can be confirmed by checking the alarms in either CAM or SANtricity.
