The systems have 2 disks configured as RAID1. If the array is in any other state than 'Optimal' (ie. 'Degraded' or 'Rebuilding') the following error is displayed and the box subsequently panics because its unable to mount the root filesystem. We've had the same experience with 2.6.7 and 2.6.9. Yesterday as a test, I installed RedHat ES 3.0 and it does not exhibit this behavior, but thats kernel 2.4 with different aacraid driver. We've also updated to the latest recommended firmware in attempt to correct this. Is there any way to make this work with kernel 2.6? Or is this expected behavior for this controller under 2.6?
