Not sure on the Windows side, as that sounds like hardware/firmware. However, on the Solaris media server try running tpautoconf -report_disc
Its possible EMM is having "issues" with the new WWNs being presented and thinks some of the drives are duplicates.
Fairly easy to clean up once you know what EMM is thinking:

Subject: [Veritas-bu] SAN Switch Change caused NBU7 to lose tape drives
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??
