Removing devices from ioscan

[Chuck J]

Hi All

Someone removed the quantum dlt from a server without shutting it down. The device is still showing in the ioscan and I want to get rid of it. I don't think just a reboot is going to fix the problem - what do I need to do:

# ioscan -funC tape
Class I H/W Path Driver S/W State H/W Type Description
======================================================================
tape 0 8/12.5.0 stape NO_HW DEVICE QUANTUM DLT7000
/dev/rmt/1m /dev/rmt/c0t5d0BEST /dev/rmt/c0t5d0DDS2Cb
/dev/rmt/1mb /dev/rmt/c0t5d0BESTb /dev/rmt/c0t5d0DDS2Cnb
/dev/rmt/1mn /dev/rmt/c0t5d0BESTn
/dev/rmt/1mnb /dev/rmt/c0t5d0BESTnb

you need to rebuild your ioinit maps.. arrrrr
or use rmsf.
But rmsf will not work in all cases.
I'll root out a post on this..

I think only rebooting will fix this

Oh yea, of course, the NO_HW state will only go on reboot. it is the HW that was know to the kernel on ioinit.

The posts I've been mentioning are if you want to reclaim that device file again you need to recreate the maps. ie hpux will not use that device file again, unless identical hw has been added in exactly the same hw path.

this is a bit of a pain for disk arrays..

I'm not near a machine right now, but I'm sure you need to look at 'ioconfig'. The search should reveal something useful from our friend JRF...

for resolve this problem use
the command :

rmsf -a /dev/special file
