NAME

6       cxl-zero-labels - zero out the label area on a set of memdevs
7

SYNOPSIS

9       cxl zero-labels <mem0> [<mem1>..<memN>] [<options>]
10

DESCRIPTION

12       The region label area is a small persistent partition of capacity
13       available on some CXL memory devices. The label area is used to and
14       configure or determine the set of memory devices participating in
15       different interleave sets. This command resets the device to its
16       default state by deleting all labels.
17

OPTIONS

19       <memory device(s)>
20           A memX device name, or a memdev id number. Restrict the operation
21           to the specified memdev(s). The keyword all can be specified to
22           indicate the lack of any restriction.
23
24       -S, --serial
25           Rather an a memdev id number, interpret the <memdev> argument(s) as
26           a list of serial numbers.
27
28       -s, --size=
29           Limit the operation to the given number of bytes. A size of 0
30           indicates to operate over the entire label capacity.
31
32       -O, --offset=
33           Begin the operation at the given offset into the label area.
34
35       -v
36           Turn on verbose debug messages in the library (if libcxl was built
37           with logging and debug enabled).
