Table 4 Device information
DataMenu Item
Reports whether advanced path failover is enabled for the SSC device server
(i.e., for the tape drive data path), and for the SMC device server (i.e., for the
media changer controller path)
Enabled
Expected FSC: A command indicator used for management of commands that
require synchronization following a link failure.
Session Status
PFSE:
1: The device server is using failover via this device server.
0: The device server is not using failover via this device server.
Failover Session Key: The key for the path (I_T_L nexus) over which the driver is
communicating with the device.
Each entry in the session list contains information about one failover session:

Local SMC device server information
If a changer has been selected in the Devices pane. The Actions→Report Local SMC menu is
available and has three sub-menu items (see Table 4 (page 57)) which provide an interface to
read state information from the selected library. The information is read directly from the library
and should match the information retained by the driver. The data is displayed in the Devices
Information pane.
