Re: HP-UX 11.31: how to rescan the new LUNs?

insf -e and ioscan -fnc disk

commands should have done the job for you. If not there should be something wrong done from the storage side. At times we just get unlucky being one of such cases rare cases where we end up having to reboot the box.

>> With the -e option, insf reinstalls the special files for pseudo-drivers and existing devices. This is useful for restoring special
files when one or more have been removed. <<

Thanks for pasting the manual excerpt here. If I needed it, I would have found it myself.

Shalom again,

In this context insf -e does nothing. Not a thing.

if insf -C disk or ioscan does not work then there is a configuration problem.

Also, LUN expansion might not be detected even with a reboot. Much better to present a new LUN and migrate the data.

Re: HP-UX 11.31: how to rescan the new LUNs?

Same happened here....rx6600 and 11.31 and had to reboot in order to see the disks. The ioscans would show NO_HW

Re: HP-UX 11.31: how to rescan the new LUNs?

I logged a call with HP and this was the response that I got, which I why I rarely call HP anymore.

"Most of the time, our customers are forced to even shutdown the array and the server and power them on again in order to help the OS to recognize the external devises."

Hi Devv,

<<
why are you posting , your problem in others man's thread, Doesn't it make you wired ????

if you have problem you should open new thread and post your problem,

Problems/issue may differ from person to person.

>>.had to reboot in order to see the disks<<

this absolutely wrong.

so far "As mentioned by <>
configuration problem. could make this happen,

ioscan -fnC disk -> you will be able to see "Newly assigned LUNS"

Re: HP-UX 11.31: how to rescan the new LUNs?

I posted here because I am having the EXACT SAME PROBLEM. So if that makes me "wired" then I'm ok with that.

Re: HP-UX 11.31: how to rescan the new LUNs?

I did an ioscan -fnC disk and we did not see the disks. This is what the problem is. We could not see the disks until after a reboot.

I would take that statement and have the call escalated to L3 support - this is patently _not_ the case and if a L1/L2 support engineer has told you this, then he needs to be re-educated.
