DESCRIPTION
The Write Zeroes command is used to set a range of logical blocks to 0.
OPTIONS
--start-block=<slba>, -s <slba> Start block. --block-count=<nlb>, -c <nlb> Number of logical blocks to write zeroes. --prinfo=<prinfo>, -p <prinfo> Protection Information field definition. ┌────┬──────────────────────────────────┐ │Bit │ Description │ ├────┼──────────────────────────────────┤ │3 │ PRACT: Protection Information │ │ │ Action. When set to 1, PI is │ │ │ stripped/inserted on read/write │ │ │ when the block format’s metadata │ │ │ size is 8.
