CXL-DISABLE-MEMDEV(1)             cxl Manual             CXL-DISABLE-MEMDEV(1)

NAME
       cxl-disable-memdev - deactivate / hot-remove a given CXL memdev

SYNOPSIS
       cxl disable-memdev <mem0> [<mem1>..<memN>] [<options>]

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, --serial
           Rather an a memdev id number, interpret the <memdev> argument(s) as
           a list of serial numbers.

       -b, --bus=
           Restrict the operation to the specified bus.

       -f, --force
           DANGEROUS: Override the safety measure that blocks attempts to
           disable a device if the tool determines the memdev is in active
           usage. Recall that CXL memory ranges might have been established by
           platform firmware and disabling an active device is akin to force
           removing memory from a running system.

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