+Contact:       linux-scsi@vger.kernel.org, linux-rdma@vger.kernel.org
+Description:   Instructs an SRP initiator to disconnect from a target and to
+               remove all LUNs imported from that target.

+Description:   Number of seconds the SCSI layer will wait after a transport
+               layer error has been observed before removing a target port.
+               Zero means immediate removal. Setting this attribute to "off"
+               will disable the dev_loss timer.

+Description:   Number of seconds the SCSI layer will wait after a transport
+               layer error has been observed before failing I/O. Zero means

+Description:   Number of seconds the SCSI layer will wait after a reconnect

+Description:   State of the transport layer used for communication with the
+               remote port. "running" if the transport layer is operational;
+               "blocked" if a transport layer error has been encountered but

+               after the fast_io_fail_tmo timer has fired and before the
+               "dev_loss_tmo" timer has fired; "lost" after the
+               "dev_loss_tmo" timer has fired and before the port is finally
+               removed.
