Use: rmsf -H
For more informatin please check man page for rmsf.

Thanks, P.Naidu

For removing the devices use rmsf:

#rmsf -H path

like:

#rmsf -H 1/0/2/1/0/4/0.199.216.128.0.1.7


after that run ioscan again.

Hi

Use rmsf -H h/w address it will remove both dsk & rdsk device files

or the more radical reboot.

If the question is how to remove the "NO_HW" lines from the ioscan listing, the answer is ONLY with a reboot. The rmsf as sugeested will delete the /dev/rmt/xxxx special files but the NO_HW lines will remain.

Hi Indrajit,

You can only get rid of the device files with "rmsf" but not the pointers in the kernel IO tree.
So, you will still see NO_HW associated with those paths until you reboot the server.

Try

# rmsf -k -H 1/0/2/1/0/4/0.199.216.128.0.0.1

Hi


if this is 11.31 then :::
1)#ioscan -s

shall show u the stale devives that is teh deviced which are having the stale DSFs and the status is NO_HW that is the DSFs now point to a HW which ahs been removed or does not exist.

2)the new option -x for rmsf removes the system wide stale entries for such stale devices.


#rmsf -x


so u can see by trying this.

Sujit

There is an easier way:

for DEV in $(lssf /dev/rmt/* | grep \?\?\?)
do
rmsf -a $DEV
done

The lssf command will show the hardware path as ??? when the device has no hardware. Note that you can use this to remove disk devices which have been removed.
