change dev file instance number
i was wondering if it is possible to change the instance numbers of devices such as the tape, disk or NIC.
I have a tape installed on an rx7640 server with the device file /dev/rmt/4m, /dev/rtape/tape5 and i want to change it to /dev/rmt/0m.
Any suggestions would be of great value, thank you

Re: change dev file instance number
There are two files that takes care of the mappings between the device files and hardware path
/stand/ioconfig
/etc/ioconfig
these files are binary and cannot be edited using editors
prior to 11.23 you would need to contact HP Response Center to get the tool ioconfig_dump
check this link

11.31 onwards there are OS commands to do this
http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1198301
they are normally used to make all the nodes in the cluster see the same device files (
ie when they are connected to same device )
The tool has to be used with caution and it can render the machine unbootable
Please assign points if you find the responses useful, thank you!!
