NAME

       cxl-zero-labels - zero out the label area on a set of memdevs

SYNOPSIS

       cxl zero-labels <mem0> [<mem1>..<memN>] [<options>]

DESCRIPTION

       The region label area is a small persistent partition of capacity available on some CXL
       memory devices. The label area is used to and configure or determine the set of memory
       devices participating in different interleave sets. This command resets the device to its
       default state by deleting all labels.

OPTIONS

       <memory device(s)>
           A memX device name, or a memdev id number. Restrict the operation to the specified
           memdev(s). The keyword all can be specified to indicate the lack of any restriction.

       -s, --size=
           Limit the operation to the given number of bytes. A size of 0 indicates to operate
           over the entire label capacity.

       -O, --offset=
           Begin the operation at the given offset into the label area.

       -v
           Turn on verbose debug messages in the library (if libcxl was built with logging and
           debug enabled).
