Setting this attribute to "off" 15 will disable the dev_loss timer. 16 17What: /sys/class/srp_remote_ports/port-<h>:<n>/fast_io_fail_tmo 18Date: February 1, 2014 19KernelVersion: 3.13 20Contact: linux-scsi@vger.kernel.org, linux-rdma@vger.kernel.org 21Description: Number of seconds the SCSI layer will wait after a transport 22 layer error has been observed before failing I/O. Zero means 23 failing I/O immediately. Setting this attribute to "off" will 24 disable the fast_io_fail timer. 25 26What: /sys/class/srp_remote_ports/port-<h>:<n>/port_id 27Date: June 27, 2007 28KernelVersion: 2.6.24 29Contact: linux-scsi@vger.kernel.org 30Description: 16-byte local SRP port identifier in hexadecimal format. An 31 example: 4c:49:4e:55:58:20:56:49:4f:00:00:00:00:00:00:00. 32 33What: /sys/class/srp_remote_ports/port-<h>:<n>/roles 34Date: June 27, 2007 35KernelVersion: 2.6.24 36Contact: linux-scsi@vger.kernel.org 37Description: Role of the remote port. Either "SRP Initiator" or "SRP Target". 38 39What: /sys/class/srp_remote_ports/port-<h>:<n>/state 40Date: February 1, 2014 41KernelVersion: 3.13 42Contact: linux-scsi@vger.kernel.org, linux-rdma@vger.kernel.org 43Description: State of the transport layer used for communication with the 44 remote port. "running" if the transport layer is operational; 45 "blocked" if a transport layer error has been encountered but 46 the fast_io_fail_tmo timer has not yet fired; "fail-fast" 47 after the fast_io_fail_tmo timer has fired and before the 48 "dev_loss_tmo" timer has fired; "lost" after the 49 "dev_loss_tmo" timer has fired and before the port is finally 50 removed. 51
