My high-level plan would be as follows: 1. hook up the HBA and SP to the second switch 2. zone the switch so the HBA can see the SP 3. Login to NaviManager and setup your initiator settings (Look for your new HBA in "Connectivity status" and set the arraycommpath, failover mode and initiator type as per emc99467 (Initiator Type: 3, Arraycommpath: 1, Failover mode:1) 4. Ensure that your existing HBA is setup with the same parameters. 5. Rescan Disks in computer manager (or reboot) 6. powermt config 7. Once you see both paths through 'powermt display dev=all' save the configuration by running 'powermt save'
If second switch has connections to SPA and SPB, then you need to zone this port to both SPs. Hopefully you did the same for the first port on the HBA. This will prevent un-necessary trespassing on the SPs. If you have Navi agent installed on the server, you will need to restart it after you completed your zoning. This will register your HBAs wwn with the actual host name. If you restarted the agent and it sill does not show the name in Connectivity status, you will need to follow Conor's suggestion and manually register it. Once that is done you will need to follow AranH suggestion here: http://forums.emc.com/forums/thread.jspa?messageID=454073
this will add the second HBAs to the storage group. Unfortunately powermt config command only works on Unix platforms so from personal experience i end up rebooting to make PowerPath manage the new path(s). Once the box reboots, run powermt display dev=all and make sure policy is set to ClarOpt for all devices. If all looks good, run powermt save and you should be good to go.

Good luck - and report back how you go!

Thanks for your instruction. I use your instruction and Dynamox link to get my box hookup with a redundant path without a reboot.
I also found out that by restarting Navisphere Agent on the W2K3 box and it will register the new paths to the SAN.
Thanks everyone,
