The Netapp doc mentioned is pretty good.

I also use the Netapp Config Advisor tool

http://support.netapp.com/NOW/download/tools/config_advisor/

you can run it before against the Filers to confirm you have multipath and after to confirm the cabling is correct.

It's picked up a few issues in the past e.g. SAS cables connected on same ASIC.

Probably obvious but the shelves also need to be power cycle after the ID has been changed.

the frist question I would as is are you multipathed and if you are adding the shelf to a new loop or existing loop. ________________________________ From: toasters-bounces@teaparty.net [toasters-bounces@teaparty.net] on behalf of Fletcher Cocquyt [fcocquyt@stanford.edu] Sent: Monday, January 20, 2014 5:26 PM To: toasters@teaparty.net Lists Subject: Re: 2240 hot add tray

You are going to disable one path. Hook it up. Re-enable the path. Disable the other Path. Hook up the second path. Re-enable the second path.

If Applicable, re-do the ACP cabling also. From what I have seen, it will automatically re-probe when there is a break in the loop.

As someone else said: MAKE SURE your shelf ID is unique! before attaching to loop.
