How to get /dev/rmt/0mn back?

[Alzhy]

An nPar has undergone several iterations of Cell and HBA moves.. everything got rebuilt, LVM fixed, etc.. etc.. etc.. However, I cannot seem to have my /dev/rmt/0mn (which is the DDS device on the CoreIO) -- and which is used by our make_tape_recovery scripts.. I have done insf and ioscan.. to no avail. I was thinking of wiping clean /*/ioconfig but...

I am thinking of just manually mknod'ing each rmt entry (ie. for mn nb...).. which should work.. but is there an easy fix so I always have my beloved /dev/rmt/0mn entry back?

No I would not take the suggestion of "change you make_net_recovery so you have -a on there"..

Gracias.

Nelson,

I'm attaching a method to create device files with names of your own choosing. I've used it in the past for just such a situation.

you can actually use mksf command to accomplish this. However, you must make sure the tape is recogniced by the server.

mksf -C tape -I ? /dev/rmt/0m

where the I is the instance assigned when you use ioscan -fnC tape.

sorry, I take that back.

the ? is the instance number and I is an option. i.e

it sshould be
mksf -C tape -I ? /dev/rmt/0m

Nelson,

what is the hw you are using for the nPar?

[Miguel Angel Aliaga_1]

Try "insf -e"

[Alzhy]

mknod - okay but tedious
mksf - easy
rm /etc/ioconfig /stand/ioconfig ;reboot - U kidding?

All works...!

The HW is a SD32000...

Have you tried

insf -H "hw-path to tape drive"

or

insf -C tape

Check the PDC firmware version - maybe you need to update it....contact HP Support
