Re: No_HW in ioscan -fnC fc

you removed some disks and still the device files are not removed.

you can remove using

rmsf -H

There is nothing to be concerned about it, when the system reboots next time they would be automatically taken off.

Did you try

#insf
and
#insf -e
then check with
#ioscan

Hi Again,

As T G Manikandan said first remove all NO_HW from your server then do a insf -e if any NO_HW hardware again came that means there are hardware which are not recognized by your kernel.

Yes..that is my concern now... I am not sure if the decives have been removed. So before executing rmsf command how do I know if the devices have been removed earlier?

Hi,

This status came when you remove a disk or LUN on you storage bay.

If you are working with fiber switches, be sure that the zoning reflect the real situation.

If you change the fiber card, the WWID of your FC is changed and the zoning doesn't match any more.

You can remove the device file with the command insf -a /dev/dsk/cxtydz and/or insf -a /dev/rdsk/cxtydz.

You could remove the device file with scripting.

Re: No_HW in ioscan -fnC fc

NO_HW means that in HP-UX, there was, at some time in the past, an actual device, but it has been removed and is no longer responding. So the device files are meaningless and you can use rmsf. If the devices come back again, use insf to create the device files.

Hi,

If those disks were a part of any VG, you would have got another errors by this time.
Also those disks will be listed in the /etc/lvmtab file. I would compare an old and a new lvmtab files and confirm it. Here it looks like you are good to go.

I apologize !
Please read rmsf in place of insf in my previous suggestion.
