Hi-
You can only add/change devices 'Hot' if the OS booted with that ldev
alive previously. You better plan on rebooting the system. You can
attach the external tape unit to the 50-pin HD SE SCSI connector. There
is such a connector on the Core IO, but it is the same bus as the
internal SE SCSI. Or, you might have a 28642A SE SCSI available in one
of the HP-PB slots. I have blown the safety fuses Hot Swapping devices
before...just to note.
On second thought, IOCONFIG might work. But I have only used it on the
newer A and N class systems.
Good luck!

Subject: Re: [HP3000-L] sysgen io info vs cstm->map info
Thanks for that detail, well worth having!
Another query...When we had a 928 at this site, its internal tape drive
died, and we sent up an external unit, and plugged it into the scsi
socket on the rear, configured it as ldev 8, and used that - on site
personnel really not up to opening the case and swapping internal drives
IMHO.
If this external unit is still on site (should be!), and its at least a
DDS2, and if there is an SE scsi socket on the rear of the system, we
should be able to plug it in there.....Looks like there are both SE and
FW SCSI sockets on the back.
If the drive was ldev 8, its scsi address WONT be 0, so it wouldn't
conflict.
Plugging it into a running system - would it be seen or not ? Does CSTM
MAP go out and look at everything ?
Cant hurt anything if connected while powered off, then powered on ? I
know have powered down external tapes , disconnected, reconnected and
powered up many times before without issue.
thanks
Regards,
John Pitman

John-
1) Make sure he shows up with a Torx set. ;-)
2) Make sure he does not bend any pins on the internal scsi ribbon
cable.
3) SCSI ID 0 on that DDS-3 : all jumpers open

Thanks.
I am trying to avoid having to guide somebody with poor English through
ODE and mapper and back out again. I hope that if they install a new
drive and reboot, and can see the tape part no with same scsi address as
before , it should be good. I will also get them to test reading an old
tape, and writing a new one before tech leaves the scene....
Regards,
John Pitman

Those aren't ldev's that cstm is showing - they're simply numerical
instances.
The scsi address of ldev 7 is defintely 0 - as shown by sysgen and cstm.
