if you are presenting VMFS LUNs to the Windows server storage group, i would expect to see them listed just like your two NTFS LUNs (unless CommVault is doing some kind of magic and hides one path).   The fact that the VMFS LUNS are not presented to the second HBA is what I am wondering is causing the issues.  Plus, according to Navisphere there are about 10 luns that are sitting on SPB.  So, is my guess correct that when this server tries to backup the data on those luns located on SPB, it is tresspassing the luns to SPA so that it can complete?  if this in fact is happening ( it could), you can get into trouble (trespass storm), where your backup server tresspasses the LUN to SPA and then VMware trespasses it back to SPB ..so you get into this tug of war. I would make sure each HBA is zoned to SPA and SPB.
