--- 667 unchanged lines hidden (view full) ---
712Some backends may allow setting the size (e.g. the ramdisk backend) and for
713others the size may be implicit (e.g. the block backend).
714.It Fl S Ar serial_num
715Specify the serial number to be used in the
716.Tn SCSI
717INQUIRY VPD page 0x80 data.
718.It Fl t Ar device_type
719Specify the numeric SCSI device type to use when creating the LUN.
720For example, the Direct Access type is 0.
721If this flag is not used, the type of LUN created is backend-specific.
722Not all LUN types are supported.
723Currently CTL only supports Direct Access (type 0) and Processor (type 3)
724LUNs.
725The backend requested may or may not support all of the LUN types that CTL
726supports.
727.El
728.It Ic remove
729Remove a LUN.
730The backend must be specified, and the LUN number must also be specified.
731Backend-specific options may also be specified with the
732.Fl o
--- 138 unchanged lines hidden (view full) ---
871other LUNs on this host, not accessible otherwise.
872This allows to offload copying between different iSCSI targets residing
873on the same host in trusted environments.
874.It Va readcache
875Set to "off", disables read caching for the LUN, if supported by the backend.
876.It Va readonly
877Set to "on", blocks all media write operations to the LUN, reporting it
878as write protected.
879.It Va reordering
880Set to "unrestricted", allows target to process commands with SIMPLE task
881attribute in arbitrary order. Any data integrity exposures related to
882command sequence order shall be explicitly handled by the application
883client through the selection of appropriate commands and task attributes.
884The default value is "restricted". It improves data integrity, but may
885introduce some additional delays.
