Hi guys,

I have a problem with Dell PowerEdge 2400 running FreeBSD 4.6 RELEASE
- four SCSI 16.9GB HDD Seagate drives as RAID 5.

I got this error today:

aac0: **Monitor** ID (0:03:0); Timeout Detected (Sync) [Aborting
Command 0x03]Srb: )xa0668cf0, Status: 0x00

The system is with RAID 5 - Dell Perc 2i/Si and so far was working
just perfect! 

dmesg shows:

aac0: i960RX 100MHz, 54 MB cache memory, no batery support
aac0: Kernel 2.1-3, Build 2939, S/N 880ad0

At boot time the RAID BIOS shows:
the following containers have missing members and are degraded:
Container#0-RAID-5
Container status - CRITICAL

Obviously, something is wrong with the RAID, but all disc light are
green - no error lights! 'fsck' didn't show any errors, too!

Any ideas are welcome!

Is there any way to find out which HDD (from the four) is the reason
for this, or is there a tool to *correct* the CRITICAL status?

-Miro
