IBM TS7530 zoning
At first, as we prepped the zoning for the VTL, we did it WWN-based. Now the trouble with the HBA’s of the VTL is simply that it has different WWPN’s on the same WWN. And WWN-based zoning simply doesn’t allow access to that. So off we went and switched to Switchport-based zoning, and see. It just works 🤷
