Login Target Filter (-p tf)
When FC-Switch is used, restrain unnecessary logging in to target ports from adapter ports. If this
parameter value is set to pid, the driver does not log in to target ports that have the same upper 2 bytes in 3
bytes of the PORT ID of the Adapter itself. This option may be effective on the FC-Switch without zonings,
for example, FC-Switches with Access Gateway mode enabled.
When FC-Switch is used with Access Gateway mode, the boot time of the OS might be prolonged because
unnecessary FC accesses arise between the FC ports that are not separated by zoning. If this option is set
to 'pid', the driver can decrease unnecessary access.
Please read Access Gateway mode in the manual of the FC-Switch.
In virtual fibre channel with Windows Server 2012 or later Hyper-V environment (by configuring 'hfcmgr -p
npiv enable' command), default value is pid.
Notice: If this feature is enabled, refer to the following information.
・Depending on the configuration of the FC-Switch, the upper two bytes of the PORT_IDs of the target
port of the connection destination and the adapter port of the connection source might correspond to
each other unintentionally. In the above setting, if this option is set to pid, login to the target port might
fail. In such a situation, change the setting of this option and the "Login Target Filter Ext" (-p tfx) so that
the "Login Target Filter Function" will be off, or reconfigure the upper two bytes of the PORT IDs on the
FC-Switch not to correspond to each other. After the configuration is complete, execute a Target Scan
command, and then re-recognize the target.
When setting this function, please also refer to Login Target Filter Function.
・If 16G Fibre Channel Adapter is used, this option does not make any effects. If 16G Fibre Channel
Adapters are needed to be configured, refer to the "Login Target Filter 16G (-p tfx)" entry.
