Paths between CX4 and ESXi

I have a CX4, which had just 4Gb host-side ports. We recently added 8Gb host-side ports and a new pair of 8Gb switches.

I connected the new 8Gb switch ports and created zones on the new switch.

When I moved a set of host-ports from the 4Gb switch to the 8Gb switch, that's when things started going south.

I have created a zone on the 8Gb switch and added both the CX ports and the host-ports.

On the CX array, it showed (under connectivity status) that the host-ports on the 4Gb network were offline, and it showed the new 8Gb ports. They were the same WWN obviously, so I de-registered the 4Gb ports and registered the 8Gb ports. Thought everything would be fine.

On the ESXi side of the house, it shows the same HBA's as before, but under "paths", its not showing any of the luns which were previously mapped to the esxi host.

I tried using esxi rescan but couldn't get the luns to show-up.

I moved the physical ports back to the 4Gb switch, and am still stuck, as the paths are still missing.

Any suggestions on how to proceed?

The goal is to move the host HBA's over to the 8Gb switch, and still see the CX4 luns...

Oh, by the way, the CX array doesn't recognize the host as an esxi server, not sure why. Seems like a missing agent or somthing. Is that also easy to fix?
