316 .It Ic write
317 Read data from a file or stdin, and write the data to the device using the
319 WRITE command.
320 .Bl -tag -width 12n
322 Specify the starting Logical Block Address for the WRITE.
327 Specify the length, in 512 byte blocks, of the WRITE request.
329 Specify the source for the data to be written by the WRITE command.
331 .Sq -
352 to the kernel when doing a write, just execute the command without copying

454 This option is a no-op for CTL.
458 This option is a no-op for CTL.
478 .It Ic delay
479 Delay commands at the given location.
490 .Bl -tag -width 12n
492 Delay command(s) at the specified location.
496 Delay command(s) for the specified number of seconds.
498 If set to 0, it will clear out any previously set delay for this particular
501 Specify the delay type.
503 .Ic delay
504 option will delay the next command sent to the given LUN.

561 .It write
562 The error should apply to WRITE(6), WRITE(10), WRITE(12), WRITE(16), WRITE
565 The error should apply to both read and write type commands.
576 This option is only applies when read and/or write patterns are specified.

731 are specified -- LUN will be mapped.
736 is not -- LUN will be unmapped.
741 are specified -- LUN mapping will be disabled, exposing all CTL LUNs.
742 .Bl -tag -width 12n
761 .Bl -tag -width 14n
774 Specify the LUN-associated string to use in the
781 Specify a backend-specific name/value pair.
796 If this flag is not used, the type of LUN created is backend-specific.
798 Currently CTL supports Direct Access (type 0), Processor (type 3)
806 Backend-specific options may also be specified with the
809 .Bl -tag -width 14n
819 Specify a backend-specific name/value pair.
828 .Bl -tag -width 14n
838 Specify a backend-specific name/value pair.
855 .Bl -tag -width 11n
865 This will also display any backend-specific LUN attributes in addition to
866 the standard per-LUN information.

943 Some options are global, others are backend-specific.
946 .Bl -tag -width 12n
956 Specifies LUN EUI-64 identifier.
962 EXTENDED COPY command access the LUN.
963 Non-unique LUN identifiers may lead to data corruption.
968 Specified LUN text identification information (UTF-8 string).
973 Setting to "on" allows EXTENDED COPY command sent to this LUN access
980 Set to "on", blocks all media write operations to the LUN, reporting it
981 as write protected.
999 of backing stores without prefetch/write-back.
1007 Specifies medium rotation rate of the device: 0 -- not reported,
1008 1 -- non-rotating (SSD), >1024 -- value in revolutions per minute.
1010 Specifies nominal form factor of the device: 0 -- not reported, 1 -- 5.25",
1011 2 -- 3.5", 3 -- 2.5", 4 -- 1.8", 5 -- less then 1.8".
1028 Specify maximum allowed number of LBAs per WRITE SAME command to report
1030 .It Va avail-threshold
1031 .It Va used-threshold
1032 .It Va pool-avail-threshold
1033 .It Va pool-used-threshold
1034 Set per-LUN/-pool thin provisioning soft thresholds.
1038 Pool thresholds are working only for ZVOL-backed LUNs.
1040 Set to "off", disables write caching for the LUN, if supported by the backend.
