OFFICE MEMO IBM DCAS 32160 help! Date:
5/4/98
Hi.
I am getting some nasty device timeouts and resulting scsi bus resets on
a RedHat 4.2 (2.0.32) system.
Here is the Picture: (This all used to work fine)
Buslogic BT958
IBM DCAS32160 Fast/Wide SCSI disc 2.1gb (id 0)
Fujitsu MO removable drive (narrow) (id 1)
Tandberg Tape drive TDC4120 1.2gig (id 3) (terminated)
The linux system resides on a eide drive hda, the scsi is for database
files (Pick D3 native)
The system has been in use for around 8 weeks, I removed it from use
whilst I was away overseas for a few weeks. When I tried to restore the
Pick Data files from the Tandberg tape drive I get the following
messages:
>kernel : scsi : aborting command due to timeout : pid 25144, scsi0,
channel 0, id 0 , lun 0 write (6) 1c dc ca 40 00
>kernel : scsi0 : Aborting CCB #25157 to Target 0
>kernel : scsi : aborting command due to timeout : pid 25153, scsi0,
channel 0, id 0 , lun 0 write (10) 00 00 22 2d 96 00 00 f4 00
etc etc. About a second later, I get a SCSI host 0 abort, pid 25144,
timed out - resetting, and the scsi bus is reset.
I have restored the tape on another machine in case there was some
problem with the data, but it's fine.
I have checked termination, cables and addresses. All seem fine.
It seems to me that the DCAS might have gone bad, but if I write linux
files to the spare partition on it, there is no error.
Any advice on how to track this down and what to look for would be
appreciated. I am going to pull the DCAS for the present and put the
PickD3 data on a spare eide drive to get the system going. Hopefully
that will work...... (at least it will separate the DCAS from the rest
of the scsi bus!)
Michael
