Hiya. I am having some strange errors that nobody seems to know how to
It all started when one of our SCSI drives failed and had to be
replaced. After this occurance I moved the SCSI tape drive from a
workstation to the SCSI Tower on the server and installed ARCSERVE 6
|from Cheyenne on the server.
I then moved the tape drive to an internal SCSI channel on the server
using an Adaptec 1520 scsi card, to see if this was causing the problem
but the problem remains even with two scsi buses.
Now when I load ARCSERVE I get periodic SCSI error messages at the
server console. The following message pops up every 13 minutes when
ARCSERVE is loaded:
10/3/96 9:56:25 am Severity = 5.
0.0.0 (SDMSNET3) SCSI Check Condition: SenseKey=MEDIUM_ERROR (8D000003)
The external SCSI tower has 5 drives:
ID Model SIZE
00 Seagate ST31200N 1 gig
01 Quantum DSP3210S 2.14 gig
02 Fujitsu M2694ES-512 1 gig
03 Micropolis 2105 500 meg
04 Seagate ST32155N 2.1 gig <--- terminated
The tape drive is as follows:
01 Conner CTMS 3200 2 gig -TAPE BACKUP-
Tech support for every part of this system wasn't able to help, from
Cheyenne to the SCSI card manufacturer to the PC manufacturer.
I am using a DFI SHA-1500P PCI SCSI card on the server scsi drive tower
with the latest drivers (NCRSDMS3.DSK)
The Adaptec 1520 card is using the latest AHA1520.DSK and ASPITRAN.DSK
The server is a Netware 3.11 P90 system with the entire SCSI system in
an external tower. (except for the tape drive)
I also received the following error messages last week which are
probably a symptom of the same problem:
10/3/96 8:22:47 am Severity = 5.
0.0.0 (SDMSNET3) CAM Error: CMD_TIMEOUT (8D000003)
10/3/96 8:22:47 am Severity = 4.
1.1.10 Device #3 (8D030) MICROP :2105-08MQ1068605:2401 deactivated due
to drive failure.
At this point the server had to be downed and rebooted. After I unloaded
ARCSERVE however none of these messages has appeared.
Any help resolving these issues will be greatly appreciated, I have
gotten no help from anyone responsible for this hardware and am getting
desperate, I really need to know what is causing this. I believe it has
something to do with the power on the SCSI bus, but am just guessing.
All my SCSI drives have many options for SCSI Term power, etc. but I
cannot find *anywhere* information on how an external SCSI tower should
be setup with many drives.
Thanks in advance for any suggestions you may have,
