Both controllers in a Sun StorEdge 6130 array have an ethernet network port connected to a LAN for management of the array. If there is a very high volume of traffic on this LAN then this could result in both controllers rebooting. Examples of possible triggers for a high volume of LAN traffic are a "Denial of Service" attack, or a network misconfiguration causing a "routing loop".

The reboot of both array controllers simultaneously will result in all data on the array going offline, and all attached data hosts losing access to that data.

This issue can occur on the following platform:

• Sun StorEdge 6130 Array with controller firmware 06.12.10.11 (as delivered in patch 117856-19) or earlier and without controller firmware 06.12.27.10

If the described issue occurs, the array's log file (Major Event Log) will show a controller reboot at the same time on both the "A" and "B" controller:

There is no workaround. Please see the "Resolution" section below.

This issue is addressed in the following release:

• Sun StorEdge 6130 Array with firmware 06.12.27.10 (or later)

Note: Controller firmware release 06.12.27.10 is supplied with Sun StorageTek Array Host Software (CAM) 5.0 available for download at:

• http://www.sun.com/download/products.xml?id=44e37d78

This is Engenio CR 98081.

The bug is that the controllers spend too much time handling the excessive network traffic and this results in Watchdog Timeouts on both controllers.

The fix in firmware 06.12.27.10 involves recognizing a state of "receive flooding" and not allowing this state to consume too much controller resources.
