...well your DR is 'probably' on a different subnet, so let me ramble a minute.
OK you got clean server and clean disk...Yep, you could ignite the box from the old server, but watch out for software that depends on the server IP for licensing...and your DR server must have it's IP changed (different subnet), then your going to have to address every software that is affected by things such as this. Watch for this cause if your backup software will probably need some tweeking before you can do any restores from tape.
...the whole thing with the IP on your MC/SG package becomes somewhat moot, because your probably not running MC/SG at your DR site based on what I read in your post, so your right, just turn it off.
...so what's left is ensure your software licensing, and software tweeking, for things you must absolutely have is in place (I like the ones that have back doors to extend the license for xx days...so handy till I get a fresh one). Your system files are there from the ignite you did, so your ok there.
.....,,I'm still rambling.......
Anyway, once your box is up at your DR site, your software(s) is working, all you need to do is mkdir the directories, set up your disks, create your vg's/lvols and mount them up. Now start tape restoring...while this is happening mgmt will be stressing cause it's taking too long and affecting business, and this is your golden opportunity to explain to them why it may have been worth it to look at more robust DR solutions......but be careful not to come off like an "I told you so..."
With good planning and depending on the amount of data you may be up in xx days.
Sure that others can think of plenty more,
Rgrds,
