What is/was the resolution process?

Rescan vmhbas with below results:
     [root@fmsuesxdev02 root]# esxcfg-rescan vmhba2
     Rescanning vmhba2...done.
     On scsi2, removing: 0:20 0:21 0:100 0:101 0:102 0:103 1:0 1:1.
     On scsi2, adding: 0:20 0:21 0:100 0:101 0:102 0:103 1:0 1:1.

     [root@fmsuesxdev02 root]# esxcfg-rescan vmhba3
     Rescanning vmhba3...done.
     On scsi3, removing:.
     On scsi3, adding:.
     
Recheck vmfs volumes (still not present)
      [root@fmsuesxdev02 root]# cd /vmfs/volumes
      [root@fmsuesxdev02 volumes]# ls
      43ce6274-6a168a26-2079-0011259d2f3d  local-fmsuesxdev02:storage1
      4682b152-755eea3d-ec57-00145eed8a86  NA-SAN-ISO
      4873da40-8360b201-01f9-001a64899050  SAN-ISO

Remove blade WWPNs from McData Zones and rescan to remove from ESX

Re-add blade WWPNs to McData Zones and rescan.  No change.

In VI Client Main Console LUNs are seen in Configuration >  Storage Adapters
But Not in Configuration > Storage
 
Log on to individual blade in VI Client and have Same results as in Main Console.
When I select Add Storage & the LUNs are seen but re-adding in this manner would reformat and delete all existing data.
 
Several times prior to the upgrade the blades have "lost" the LUNs and this was able to be rectified by "rescanning" the vmhbas.

Have you used the update manager to install all recent patches on the ESX systems ?

Often these kinds of problems come from bugs and these can often be solved by applying all patches.

The unpleasant answer was found in the VMware KB Article: SAN LUNs damaged after ESX installation, upgrade, or reinstall KB 1003881- url http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1003881&sliceId=1&docTypeID=DT_KB_1_1&dialogID=11558587&stateId=0%200%2014387862
