We have a mixture of new and older switches in our redundant fabric. The older switches need to be moved onto a different subnet. Can this be done "on the fly" without affecting the production SAN on the fabric? We have redundant fabrics with everything dual ported. I was trying to plan downtime if needed. The FOS on the switches in question is 6.2 switch type is 32 (4100), if I remember correctly.

Oh...and "yes I know" dual ported redundant fabric switches will allow for this. Upper managment doesn't want ANY fabric reconfigurations that will generate a fabric event that would cause a failover.

I like this

Then best to never touch anything again which is hooked up to the switches. Your never going to get 100% guarantee, best for upper management to realize that.
That said setting new ipadresses should not impact what so ever, apart from management interface being unavailable for a brief moment.
Make sure you have a working (tested) serial connection in the event something goes wrong (typo in the netmask/gw or whatnot)
The command you're looking for is ipaddrset on the CLI, webtools will allow you to do the same.

Additional question: When we have had problems with a switch and it dropped out of the fabric, I have noticed that the fabric tries to find the switch via IP (message on web gui) trying to resolve IP. Will changing the IP, cause the fabric to refresh?
