RP4440 tape drive attached to SCSI Channel B LVD/SE card

[nightwich]

Hi Peter


After you attach the tape you need to run a ioscan -fun to detect new hardware.

Then do insf -e to install special files.


Then you do a ioscan -funC tape to see if your tape is already reconized.

Reply if you need directions.

Hi Nightwich,

I did ioscan -funC tape, did not return anything.

From my previous message, my question is: Should I plug the inside cable to channel B (it wasn't plug in initially)and plug the outside channel B to the tape drive?

[Torsten.]

Don't remove the internal cables. There is a terminator at the end of the cable, which is needed.

Your disks are in "simplex" configuration, so you can use the external connector B.

Did you use a terminator at the tape drive side?

Check for bent pins too.

Hi Peter,

Paste the output of the following commands:

kcmodule -a | grep -i tape

ioscan -funC tape

Also you need to have a scsi terminator on the tape.

Regards.

Torsten,

Tape drive does have a terminator. I will insert the internal B channel cable, and try again.

Nightwich,

# kcmodule -a | grep -i tape
sh: kcmodule: not found.
#
# ioscan -funC tape

OS is:
HP-UX rp4440 B.11.11 U 9000/800 637230314 unlimited-user license

One more piece of info:

I set tape drive SCSI id to 7

[Patrick Wallek]

No, no, no. You cannot use 7. That is the ID of the SCSI controller card itself. Use another ID.

Hi peter.


kcmodule if for 11.23 and 11.31

to 11.11 you should use:

# kmadmin -k | grep -i tape
tape2_included
tape2
stape


This should be the output.

Regards.

Patrick,

I will change scsi id to 5 and try again. The big question is: Should I plug in the internal cable B to the internal channel B? Which was un-plug in before I started the external backup tape "project".

Have a look at this manual:

http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01883140/c01883140.pdf

Particularly you need to read the section "Converting SCSI From Simplex to Duplex" starting on page 66.

If you are NOT converting, and thus not installing the parts they talk about (meaning you still have the short jumper cable they talk about), then my guess is that you DO NOT want to plug in teh channel B cable.
