There are several ways.

There are always symbolic links, but I would prefer rmsf -H X/X/X/X
ioscan -fnC tape
insf

Thomas,

You can make the device files yourself and name them whatever you like. See the explanation in this thread:

Easier to change the application values I think.

If I understand your question, you want to change the SCSI target ID's. There are procedures, but, like I said, I would change the application first.

Procedure I

a) ioscan -fnkC tape | grep -e INTERFACE -e DEVICE | grep -v target | awk '{ print $3, $1 $2 }' > /file

NOTE: store file in / (root).

b) vi /file and make changes.

c) init 1 (* don't reboot and come up to init 1 through single user *)

d) /sbin/ioinit -f /file -r

e) automatic reboot

f) Will fail if instance now bound to other HW.

Procedure II

a) Repeat Ia
b) Repeat Ib
c) mv /stand/ioconfig /stand/ioconfig.sav

mv /etc/ioconfig /etc/ioconfig.sav

d) Due to missing ioconfig file system will stop at
ioinitrc:: # /sbin/ioinit -c
ioinitrc:: # /sbin/init -f /infile -r

e) reboots automatically.
