Try turning off SYNC mode on ALL your drives in the SCSI BIOS. I had a
similar problem this last weekend with 2.2.14 and 5.1.21 AIC-7xxx and async
mode fixed it. I had been previously running SYNC mode with no problems,
but I added two new drives and couldn't get the mkraid to finish without
hitting the same errors you're seeing. All my drives are now running async
and are happy. Slow, but happy. Previously (on 2.2.14 and prior) they were
running happy in sync mode but I was upgrading this weekend and had to do a
mkraid again (which really bangs the SCSI bus during resync). I tried
several times with different sync/async combos with no joy. I thought this
was just my config on the one machine but, this morning I had a problem on
another box which is a 3x50G 2940U2W setup. I accidentally left it NFS
mounted and during the attempted backup it also hit some SCSI timeouts -- it
recovered though. This box has been flawless for a long time (I think it
must've been the network I/O causing this -- no proof yet -- just
suspicion).

Subject: Argh, more problems with SCSI and RAID
Hi all,
I'm trying to do 2 things with SCSI/RAID both of which are having
problems. Any help would be greatly appreciated. My system is 2.2.14 with
the 5.1.22 Adaptec AIC-7xxx drivers.
First, I'm trying to get 4 SCSI drives working. Forget RAID, forget
anything complex, I just want them working. I actually had 5 until yesterday
when one decided to start making loud noises which I intrepreted as death
throws. Anyway, the problem is that after I start up my 4 drives, at some
point, I get this:
Feb 1 02:48:01 dual kernel: scsi : aborting command due to timeout : pid
10920, scsi1, channel 0, id 0, lun 0 Read (6) 00 06 df 60 00
Feb 1 02:48:03 dual kernel: scsi : aborting command due to timeout : pid
10921, scsi1, channel 0, id 1, lun 0 Read (6) 00 07 c7 08 00
Feb 1 02:48:03 dual kernel: scsi : aborting command due to timeout : pid
10922, scsi1, channel 0, id 1, lun 0 Read (6) 00 07 d7 48 00
