SAN Switch replacement

Icoaty — Wed, 07 Nov 2007 03:53:52 GMT

Hi
I need to replace a B series SAN Switch 4/16 with a B series SAN switch 4/64. While researching the use of uploading and downloading config files I discovered a recommendation not to use config files from different models of switches. Would anyone know of any documentation or whitpapers detailing the best procedure to perform this migration.

Ian,

How much do you have configured on the switch? is it mainly zoneing stuff you want to bring across?

I take it your're also trying to keep downtime to a minimum.

I can think of a couple of ways you can get around this:

Export the config from the old and the new switches - then copy the parts that you want to bring across into the exported config from the new switch (i'd make a copy first) and re-import it.

OR

Depending on your licences on the switches, connect the new switch to your existing fabric. You should then be able to setup the Zone's and/or have them migrate into this switch. Save the config and then swap in the new switch.

Is this switch in a fabric? Is it redundant? If you added the switch to the fabric, you could add a new port alias to the zone and move the cable. There would be minimal downtime for the host. Later remove the old port. etc etc.
