DESCRIPTION

The Write Zeroes command is used to set a range of logical blocks to 0.

OPTIONS

−s <slba>, −−start−block=<slba>

Start block.

−c <nlb>, −−block−count=<nlb>

Number of logical blocks to write zeroes.

−p <prinfo>, −−prinfo=<prinfo>

Protection Information field definition.

−r <reftag>, −−ref−tag=<reftag>

Optional reftag when used with protection information.

−m <appmask>, −−app−tag−mask=<appmask>

Optional application tag mask when used with protection information.

−a <apptag>, −−app−tag=<apptag>

Optional application tag when used with protection information.

−l, −−limited−retry

Sets the limited retry flag.

−d, −−deac

Sets the DEAC bit, requesting controller deallocate the logical blocks.

−f, −−force−unit−access

Set the force−unit access flag.

−n <nsid>, −−namespace−id=<nsid>

Namespace ID use in the command.

−S <storage−tag>, −−storage−tag=<storage−tag>

Variable Sized Logical Block Storage Tag(LBST).

−C <storage−tag−check>, −−storage−tag−check=<storage−tag−check>

This bit specifies the Storage Tag field shall be checked as part of end−to−end data protection processing.

−T <dtype>, −−dir−type=<dtype>

Directive type

−D <dspec>, −−dir−spec=<dspec>

Directive specific

−Z, −−namespace−zeroes

If set, then the controller clear all logical blocks to zero in the entire namespace.

−o <fmt>, −−output−format=<fmt>

Set the reporting format to normal, json or binary. Only one output format can be used at a time.

−v, −−verbose

Increase the information detail in the output.

−t <timeout>, −−timeout=<timeout>

Override default timeout value. In milliseconds.
