Installing the Windows advanced path failover drivers
“Application path list ” (page 36) shows the device handles as presented to a Windows application
when using the advanced path failover driver for the same hardware configuration shown in
“Advanced path failover” (page 11). For the drives, both ports are mapped to the same device
handle and one port is active while the other is the standby port. For the library, the two ports on
the first drive are the active and standby ports and two additional ports on a second drive are
passive ports that can be activated in the event of complete connection loss to the drive hosting
the control path.
