Dear All,
I've added a new disk to my alphaserver 1200 (4.0D), its the RZ1CB-CS in
the list below.
Jul  1 11:03:23 omni vmunix: scsi1 at isp0 slot 0
Jul  1 11:03:23 omni vmunix: rz8 at scsi1 target 0 lun 0 (LID=1) (DEC
RZ1CB-CA (C) DEC LYJ0) (Wide16)
Jul  1 11:03:23 omni vmunix: rz9 at scsi1 target 1 lun 0 (LID=2) (DEC
RZ28M    (C) DEC 0616)
Jul  1 11:03:23 omni vmunix: rz10 at scsi1 target 2 lun 0 (LID=3) (DEC
RZ28     (C) DEC D41C)
Jul  1 11:03:23 omni vmunix: rz11 at scsi1 target 3 lun 0 (LID=4) (DEC
RZ28M    (C) DEC 0616)
Jul  1 11:03:24 omni vmunix: tz12 at scsi1 target 4 lun 0 (LID=5) (DEC
TLZ07     (C)DEC 553B)
Jul  1 11:03:24 omni vmunix: rz13 at scsi1 target 5 lun 0 (LID=6) (DEC
RZ28D    (C) DEC 0010)
Jul  1 11:03:24 omni vmunix: rz14 at scsi1 target 6 lun 0 (LID=7) (DEC
RZ1CB-CS (C) DEC 0844) (Wide16)
I disklabel'd it, and newfs'd it. I then started to generate some data
and write to the new disk.
About 6 hours later the whole machine crashed. I restarted the machine,
without the new disk. THe next day I mounted the new disk by hand, and
started to fsck it. THe whole machine locked up for minutes at a time,
till I was able to kill the fsck, and then the box came back to life
normally. 
I'm getting CAM errors reported in the kern.log like this:
Jul  1 12:50:39 omni vmunix: cam_logger: CAM_ERROR packet
Jul  1 12:52:19 omni vmunix: cam_logger: bus 1 target 6 lun 0 
Jul  1 12:52:19 omni vmunix: ss_perform_timeout

Jul  1 12:52:20 omni vmunix: Active CCB at time of error
and out of uerf like this:

Various TARGETS are reported.
We had a couple of visits form compaq engineers recently, and one of them
mentioned that my SCSI bus was not terminated, and when he came back to
replace a mother borad, he would bring some terminators. Unfortunately, I
got a different chap the next day, and no terminators. Had had no disk
problems so I was not immediately concerned.
Are no terminators for my SCSI bus going to cause problems/symptoms as
above, or may there be another problem.
Thanks,
Bob
