I'm trying to make work a HP Surestore DAT24 on SGI Octane
(IRIX64 6.5.24f); so I added the usual lines to
/var/sysgen/master.d/scsi:

{ DATTAPE, TPDAT, 2, 6, "HP", "C1537A" /*DAT*/, 0, 0, {0},
MTCAN_BSF|MTCAN_BSR|MTCAN_APPEND|MTCAN_SETMK|MTCAN_PART|MTCAN_PREV|
MTCAN_SYNC|MTCAN_SPEOD|MTCAN_CHKRDY|MTCAN_VAR|MTCAN_SETSZ|
MTCAN_SILI|MTCAN_SEEK|MTCAN_CHTYPEANY|MTCAN_COMPRESS,
40,4*60, 4*60, 5*60, 3*3600, 512, 64*512,
tpsc_default_dens_count, tpsc_default_hwg_dens_names,
tpsc_default_alias_dens_names,
{0}, 0, 0, 0,
0, (u_char *)0 },

and autoconfig -fv the system; but when I try to boot with
the unit connected (to external SCSI bus), system won't boot.
All it says is:

ql1: <6>Command timeout, draining ctlr IO for as long as 10 seconds
ql1d3: <6>SCSI command timeout: 1 commands: <6>0x28 <6>

Note: "hinv" from prom monitor shows the tape

I think it is the "recommended" block size. I guess you will
get more speed with 512...

: Do you have another machine you can attach it to in order to verify drive is
: okay? You might also be able to verify the cable and terminator with another

I will try; but the unit was working some time ago on Indy/6.2

: Are there any other devices connected to the external SCSI bus?

Yes, a CD-ROM and a disk drive. I tried to connect only the
disk and the DAT, but it made no difference.

The SCSI error messages point to a hardware problem, your sw settings
should usually not result in such messages.

I would check the cable and terminator.

I will try another cable (already tried two).

The drive is working, I just tested it on a PPC G4 and
Retrospect can use it (same terminator, different cable)
