+What: /sys/class/srp_remote_ports/port-<h>:<n>/delete
+Date: June 1, 2012
+KernelVersion: 3.7
+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.
+
+What: /sys/class/srp_remote_ports/port-<h>:<n>/dev_loss_tmo
+Date: February 1, 2014
+KernelVersion: 3.13
+Contact: linux-scsi@vger.kernel.org, linux-rdma@vger.kernel.org
+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.
+
+What: /sys/class/srp_remote_ports/port-<h>:<n>/fast_io_fail_tmo
+Date: February 1, 2014
+KernelVersion: 3.13
+Contact: linux-scsi@vger.kernel.org, linux-rdma@vger.kernel.org
+Description: Number of seconds the SCSI layer will wait after a transport
+ layer error has been observed before failing I/O. Zero means
+ failing I/O immediately. Setting this attribute to "off" will
+ disable the fast_io_fail timer.
+
+What: /sys/class/srp_remote_ports/port-<h>:<n>/port_id
+Date: June 27, 2007
+KernelVersion: 2.6.24
+Contact: linux-scsi@vger.kernel.org
+Description: 16-byte local SRP port identifier in hexadecimal format. An
+ example: 4c:49:4e:55:58:20:56:49:4f:00:00:00:00:00:00:00.

+What: /sys/class/srp_remote_ports/port-<h>:<n>/reconnect_delay
+Date: February 1, 2014
+KernelVersion: 3.13
+Contact: linux-scsi@vger.kernel.org, linux-rdma@vger.kernel.org
+Description: Number of seconds the SCSI layer will wait after a reconnect
+ attempt failed before retrying. Setting this attribute to
+ "off" will disable time-based reconnecting.
+
+What: /sys/class/srp_remote_ports/port-<h>:<n>/roles
+Date: June 27, 2007
+KernelVersion: 2.6.24
+Contact: linux-scsi@vger.kernel.org
+Description: Role of the remote port. Either "SRP Initiator" or "SRP Target".
+
+What: /sys/class/srp_remote_ports/port-<h>:<n>/state
+Date: February 1, 2014
+KernelVersion: 3.13
+Contact: linux-scsi@vger.kernel.org, linux-rdma@vger.kernel.org
+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
+ the fast_io_fail_tmo timer has not yet fired; "fail-fast"
+ 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.
