Purpose

This document will explain the symptoms and resolution for a total loss of connectivity to a Sun StorEdge 3X00 array. The problem has become known as a "race condition".  The array goes into a state, where both controllers assume a role of primary. You know this has occurred when:

 

The cause can also be seen in single raid controller arrays SE3310, SE3510 and SE3511.


Explanation:

An incorrect NVSRAM 3.2.X exists on 4.X NVSRAM Raid Controller. Which prevents a crossload of Raid Controller firmware and NVSRAM from the primary to secondary controller during a power on sequence or  a controller reset (initiated by an sscli command "sscli> reset controller")



Cause:

This problem can be attributed to either an improper controller firmware upgrade, or may occur when a 3.2.X controller was installed in a 4.X array. Specifically, there is an NVRAM mismatch somewhere between the NVRAM on the controllers.
