Urgent Help: about UNKNOWN device

[yyghp]

I want to backup my system urgently.
Now, I connected the MSL6030 library tape with the system, and
#ioscan
H/W Path Class Description
===================================================
root
0 ioa System Bus Adapter (582)
0/0 ba Local PCI Bus Adapter (782)
0/0/0/0 lan HP PCI 10/100Base-TX Core
0/0/1/0 ext_bus SCSI C896 Ultra Wide LVD
0/0/1/0.0 target
0/0/1/0.0.0 unknown HP MSL6000 Series
0/0/1/0.1 target
0/0/1/0.1.0 unknown HP Ultrium 2-SCSI
...
...

How can I make it from 'unknown' to 'tape', and how can I access the tape via /dev/rmt/0mn ?
and what steps i need to take before I can run my backup utility 'make_tape_recovery' ?
Thanks !

sam
kernel

drivers

stape

put it in, build a new kernel, boot and your system should recognize the devices.

is there any other way i don't need to reboot the system ?

I thought this was covered in your previous post ....

You must add 'schgr', 'sctl' and 'stape' to your kernel. Once you've done this you can run ioscan again and you hardware should bind to the appropriate driver.

(I apologise if all of this has been covered, done and is not working)

[Stuart Abramson_2]

Check /stand/system for tape drivers, tape ,stape, etc...

# cd /stand/
# grep tape system
stape
tape2
tape2_included

If not installed, then install and rebuild the kernel with SAM.

[Helen French]

You need to install required SCSI patches and need to add the driver in Kernel. Install Ultra SCSI cumulative patches, stape cumulative patch etc.

The device will be claimed after you add the driver to Kernel and reboot.

[Michael Tully]

You cannot add these drivers without compiling a new kernel and rebooting your system. You can use SAM (probably best method for this situation)
