Re: howto get rid of NO_HW?
no, it is no need to put an ioscan output.
I would like to remove exactly the items fcp domain and ext_bus - you are staying that they cannot be removed....and I do not like the reboot....

Re: howto get rid of NO_HW?
There shouldn't be any harm in having them on the box until you have a scheduled outage. Worst case scenerio is you may see an EMS alert from that device which could be ignored or put into ems' disabled instances.

Re: howto get rid of NO_HW?
that's clear....
However, I hoped to have the procedure to clean out the NO_HW from ioscan. I do not know why it is principially impossible.

Just run the "insf -e" command and then try your ioscan command again.

Re: howto get rid of NO_HW?
Have you rebooted since the san change? (that's the sad part)
I had to do that once whne we had a san change and it cleared up the NO_HW

Re: howto get rid of NO_HW?
Geoff - no, I have not rebooted - I would like to avoid it, or - let's say - I had to avoid it.
Anyway, thanks to all with relevant answers....
It seems that this really could not be done without reboot under HP-UX.

Re: howto get rid of NO_HW?
I know this is an old thread, but I just ran into this issue. We are on 11.31 and using the multipathing. In our case we could not see a newly presented disk. I thought it was an NO_HW fcp issue. Anyway, I used rmsf -H on the actual fc's, not the fcp and it cleared up my issue. It did not remove the NO_HW for the fcp's, but I was then able to see the disk. Hope this helps someone in the future.
