problems with an scsi tape and disk with ap/sco open server

Post by open0.. » Fri, 21 Jun 1996 04:00:00



We have an SCO Open Server running over and SCSI Adaptec 2740 with
 and SCSI Streamer and DAT. The streaemer runs ok in SCO but not in
 Pick AP 6.01. When I load the Pick System the streamer goes correctly
 under  SCO and the device is /dev/rdsk/rStp0. The problem consists on
 the streamer is accesible from Pick but it always say Parity error.
Thanks in advanced.
Wishing hearing from you.

Would need to see your /usr/lib/pick/pick0 file and have more information on
the type of SCT to comment in detail.

As a guide the entry in pick0 file for our two SCT tape drives are below. The
first is a 60MB QIC02 unit, second is a 525MB SCSI.

tape /dev/nrct0 16384 q ls /dev/xct0 # tape 4
tape /dev/nrStp0 16384 q lh /dev/xStp0 # tape 5

Below is my understanding of how these entries work for tape drives

Field   Desc
1       tape (type)
2       no-rewind Unix device file
3       default block size
4       type, q=quarter inc, d=DAT (AIX only ?), v=8mm, f=floppy)
5       density (descriptive only ?) meaning varies on type
6       Unix control file for device. Important for tape status commands
7       # = comment marker

1. Ap/SCO-SCSI tape question

I have both a Wangtek QIC-02 and a Conner DAT.  How do I get AP to
recognize both devices.  So far, it only recognizes the SCO default
tape, whichever I make it.  I would like to address the Wangtek as
"set-device 2" and the DAT as "set-device 3".  Any hints?
