3ware Escalade problems

[Scott Ransom <ransom@cfa.harvard.edu>]

Hello,

After months of running a fileserver with an 8 port 3ware escalade card
(kernels 2.4.[3457] using reiserfs and software RAID5) I started getting
problems this weekend.

Over the last three days, when I try to access the drives, after a
couple minutes I get a drive failure (I even heard a "yelp" from the
drive during one of them...).  But the "failure" has happened to 3 of
the 8 drives over 3 days -- so unless there is a hardware problem that
is killing my drives I find it hard to believe that 3 drives really and
truly failed....

Here is a sample from my syslog of a failure:

3w-xxxx: tw_interrupt(): Bad response, status = 0xc7, flags = 0x51, unit
= 0x1.
3w-xxxx: tw_scsi_eh_reset(): Reset succeeded for card 1.
3w-xxxx: tw_interrupt(): Bad response, status = 0xc7, flags = 0x51, unit
= 0x1.
scsi: device set offline - not ready or command retry failed after host
reset: host 1 channel 0 id 1 lun 0
SCSI disk error : host 1 channel 0 id 1 lun 0 return code = 80000
I/O error: dev 08:11, sector 158441712

I've noticed several "issues" with the 3ware cards in the archives.  Has
anyone seen something like this?

Scott

PS:  I'm currently running 2.4.7 with the lm-sensors/i2c patches.
