OK - I'm ready for help.
I have purchased a Conner TSM4000R SCSI tape backup unit. I have found this unit
mentioned several times in questions in the mail archives, but unfortunately the
replies must have been sent directly, and not forwarded to the list.
Specs:
2G capacity uncompressed
4G compressed (software compression - can't use)
QIC-3080 tape format
neato flashing LED indicator
mt:
#mt -f /dev/rst0 status
Present Mode: Density = 0x29 Blocksize variable
---------available modes---------
Mode 0: Density = 0x00 Blocksize variable
Mode 1: Density = 0x00 Blocksize variable
Mode 2: Density = 0x00 Blocksize variable
Mode 3: Density = 0x00 Blocksize variable
dmesg:
.

.
aic0 at 0x340-0x35f irq 11 on isa
aic0 waiting for scsi devices to settle
(aic0:0:0): "HP C3724S 5153" type 0 fixed SCSI 2
sd0(aic0:0:0): Direct-Access 1149MB (2354660 512 byte sectors)
(aic0:1:0): "CONNER CTMS 3200 7.00" type 1 removable SCSI 2
st0(aic0:1:0): Sequential-Access density code 0x0, drive empty
.
.
.
Q: How do I derive the BPI and length of the tape for dump?
Q: How can I tell if this is a rewinding or non-rewinding unit (i.e. should
I use /dev/nrst0 or /dev/rst0)?
Please email if you need any additional information.
Please email respones directly and I will compile and submit a final solution to
the mailing list for archive purposes.
Thanks,
