Sun Microsystems Virtual Tape Library manual Abc De

During failover, the standby port becomes active by spoofing the WWPN of the failed port. The figure below represents a hard‐zoned SAN after VTL failover:

SAN clients include backup application hosts, such as Symantec NetBackup master servers, and ACSLS servers (if ACSLS is to control VTL virtual libraries). VTL must not share initiator ports with other SAN clients, such as physical tape devices.

Next task: When you have completed zoning, log in to the VTL server, scan for Fibre Channel devices, and make sure that all devices are visible.
