The SAN part is utterly irrelevant and trust me, you really do not
need an article to follow.
What do you do?
You create the LUNs (disks) onto the server as per the instructions
from the SAN vendor. Magically the disks appear on the server. You
then use cluster admin to add those disks as dependencies and for that
you're just going to repeat/duplicate the current disk settings. Then
you can move the stores one at a time from the current disks to the
new ones in safety.

Your SAN vendor will be the people you need to talk to, not anything
Microsoft needs to do. You need to make sure you/they configure both
nodes iSCSI initiators as able to access the LUNs (otherwise a
failover won't ever work) and you also need to reconfigure their
backup application so that it's taking the right backups at the right
time on the right disks.

It's pretty easy as Mark said.

Here's a step by step guide I did a few years back.

I'll do one on 2007 SCC later. The steps are a little different.

Luckily Oliver came through for you. It's a simple process, you just
need to be methodical when doing it.

Hi- did you do one for E2K7? Have a migration coming up soon to new SAN.

Thanks,
