sg_reset_wp - send SCSI RESET WRITE POINTER command

sg_reset_wp [/–all/] [/–count=ZC/] [/–help/] [/–verbose/] [/–version/] [/–zone=ID/] DEVICE

Sends a SCSI RESET WRITE POINTER command to the DEVICE. This command is found in the soon to be released ZBC standard (draft prior to standard: zbc-r05.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.

-C, *–count*=/ZC/

ZC is placed in the Zone Count field in the cdb of the RESET WRITE POINTER command supported by this utility. ZC should be a value from 0 to 65535 (0xffff) inclusive.

-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.
