ioscan script help needed

George_Dodds — Fri, 01 Aug 2008 06:26:01 GMT

Hi

I need a simple script to automate checking to see if disks are attached to hba's on a server.

This is how i would do it manually

ioscan -funC fc

Take note of the hardware paths

ioscan -funC disk

Check hardware paths against the ioscan -funC fc output to see that both cards are being used.

Thanks in advance

George

I don't have access to an HP system today.
Can you post output of each command?

Then I can take a stab at a script.

Cheers

I would suggest using ioscan's -F option
which renders more easily parseble output.
e.g. to catch disks' HW pathes like

$ /usr/sbin/ioscan -kFdsdisk|awk -F: '{print$11}'

Oops, sorry it was FCP paths that you wanted?

try this instead

$ /usr/sbin/ioscan -kFdfcp|awk -F: '$16~/CLAIMED/{print$11}'

The "-u" switch will hide any not CLAIMED disk or device in ioscan - remember this.

IMHO for your purpose it may be better to use an array or driver specific tool to check, like "evainfo" or "autopath display" or whatever.
I'm not really sure what result you want to get.
