6 remove all LUNs imported from that target.

12Description: 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.

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.

37Description: Number of seconds the SCSI layer will wait after a reconnect
38 attempt failed before retrying. Setting this attribute to

51Description: 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.
