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.
