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.
