Since third HBA is in VSAN2 and your Clariion is in VSAN1, you can not zone that HBA to Clariion on VSAN1 because they are in different VSAN. The only way to do that is by using IVR (inter vsan routing). Second thing, you do not want to mix disk and tape connectivity on the same HBAs, it's best to isolate tape traffic. As you can see whoever set it up went a step further and isolated tape traffic to dedicated VSAN, which is smart too.
IHAC having having 2 fabrcs (fabrics-a & fabric-b).   *2 VSAN zones in fabric-a. fabric-b has only one vsan. *In fabric-a (vsan1 is for SAN host attach zones / vsan2 is for Backup tape/vtl zones) *tape libraries / IBM vtl connected to fabric-a *eg. host1 has 3 HBAs - first & third HBA goes to fabric-a -and- second goes to fabric-b  (In fabric-a) - first HBA zoned for SAN attach in vsan1 & third HBA is zoned with Backup tape/vtl in vsan2.   My question [NAME] location:::  Is third HBA can be zoned with another CLARiiON which is in VSAN1? Is same HBA can be part of multiple VSAN?  Thanks in advance.  Regards Pras
