ioscan showing NO_HW in scan

[Daryl Rose]

Hello,

I just had several LUNs pulled away from some of the servers, HP-UX 11.23. None of these LUNs were being used and were not in any volume groups. I thought that after the LUNs were pulled away, I would be able to do an ioscan -fnC disk, and that I would no longer see them. I must be missing a step, but I'm not sure what. Can someone please tell me what I need to do to remove these devices?

Thank you.

If you use the rmsf command this will remove the relevant device files.

I remember now. I don't do as much in HP as I would like, and I had forgotten about that command.

Thank you.

Some points would be nice..

here is a quick way to take care of them all at once

ioscan with no args first to make sure you have current info.

then

ioscan -kfnC disk|awk '/NO_HW/ {print $3}'|while read list do
rmsf -H $list
done

Thanks Tim, I'll have to add that to my little bag of tricks. I'm sure I'll need to use that in the future at some point.

while we are on the subject, in 11.31, you can do just "rmsf -x" and it gets rid of all stale nodes.
