   5 Description:    Instructs an SRP initiator to disconnect from a target and to
   6                 remove all LUNs imported from that target.

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

  21 Description:    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.

  30 Description:    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.

  37 Description:    Number of seconds the SCSI layer will wait after a reconnect
  38                 attempt failed before retrying. Setting this attribute to
  39                 "off" will disable time-based reconnecting.

  51 Description:    State of the transport layer used for communication with the
  52                 remote port. "running" if the transport layer is operational;
  53                 "blocked" if a transport layer error has been encountered but
  54                 the fast_io_fail_tmo timer has not yet fired; "fail-fast"
  55                 after the fast_io_fail_tmo timer has fired and before the
  56                 "dev_loss_tmo" timer has fired; "lost" after the
  57                 "dev_loss_tmo" timer has fired and before the port is finally
  58                 removed.
