cxl-disable-memdev - Man Page

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.

-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).
