I have installed a new SCSI drive into an HP6000-SE SCSI tower conencted to an old HP9000. This device cannot be detected by SAM. HOWEVER, when doing an ioscan -f I get:

where the new disk is the ST43471N. Doing an ioscan -u gives:

and an ioscan -k:

which leaves me banging my head against a wall as to why the drive is undetected. I'll admit that I'm not too skilled in HP-UX hardware and configuration. As a hunch the dual entries of the 28655A Parallel interface in the output of ioscan -f seem suspicious.
I am about to remove the device in question and reboot the machine (this can't be done too ofter as the machine is a production server) to compare the outputs of ioscan before and after.
Any pointers? In advance, you'll save my life (and my hair) if you can help. Thanks:
