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.
