sg_reset_wp − send SCSI RESET WRITE POINTER command
sg_reset_wp [−−all] [−−help] [−−verbose] [−−version] [−−zone=ID] DEVICE
Sends a SCSI RESET WRITE POINTER command to the DEVICE. This command is found in the ZBC draft standard revision 4c (zbc−r04c.pdf).
Arguments to long options are mandatory for short options as well.
−a, −−all
sets the ALL field in the cdb. This causes a reset write pointer operation of all open zones and full zones. When this option is given then the −−zone=ID option is ignored. Either this option or the −−zone=ID option is required.
−h, −−help
output the usage message then exit.
−v, −−verbose
increase the level of verbosity, (i.e. debug output).
−V, −−version
print the version string and then exit.
−z, −−zone=ID
where ID is placed in the cdb’s ZONE ID field. A zone id is a zone start logical block address (LBA). This causes a reset write pointer operation on the zone identified by the ZONE ID field. The default value is 0. Either this option or the −−all option is required. ID is assumed to be in decimal unless prefixed with ’0x’ or has a trailing ’h’ which indicate hexadecimal.
The exit status of sg_reset_wp is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
