Have you tried cold booting the servers ?

Hi everyone,
In one of my environments we replaced our old SAN switch with a new Cisco. We went from 1 fabric on the old switch to 2 fabrics on the new Cisco switch.
We split up the tape drives 1, 2, 3, 4 on Fabric A. 5,6,7,8,9 on Fabric B.
After this switch, our media servers are having enormous trouble seeing the tape drives at all. One media server see's 6 tape drives which makes no sense at all. One media server see's all 9. Another media server see's 7.
No rhyme or reason to any of it. Why would a switch change cause this?
Our zone's have been thoroughly checked multiple times. Each tape drive is presented to the media servers, I assure you.
One of our Windows media servers see's only 6 tape drives in Device Manager, but San Surfer shows that the HBA see's all 9....
A Solaris 9 media server see's 9 tape drives, but netbackup only see's 7.
So, what do you guys think could be going on? Do I need to do something to the HBA's like reset, so they forget the previous paths? Could tape drivers be the potential issue, can tape drivers cause an issue with 1 switch over another? I am completely out of ideas so im throwing random ideas out... Anyone??
