SCSI error FC2 aacraid ...help....

[w fm3]

Hi

One of my raid containers has gone down twice in about a month.

I get the below error and sdb1 which is a mirrored container goes completely 
offline, after a reboot everything is ok, same thing happened less than a 
month ago.

FC2 2.6.10-1.12FC2smp on a Dell 2650 with PERC3/Di (adaptec)

Anyone know what the cause could be?

Thanks

Walt
