NAME

       daxctl-offline-memory - Offline the memory for a device that is in system-ram mode

SYNOPSIS

       daxctl offline-memory <dax0.0> [<dax1.0>...<daxY.Z>] [<options>]

EXAMPLES

       •   Reconfigure dax0.0 to system-ram mode

           # daxctl reconfigure-device --mode=system-ram --human dax0.0
           {
             "chardev":"dax0.0",
             "size":"7.87 GiB (8.45 GB)",
             "target_node":2,
             "mode":"system-ram"
           }

       •   Offline the memory

           # daxctl offline-memory dax0.0
           dax0.0: 62 sections offlined
           offlined memory for 1 device

DESCRIPTION

       Offline the memory sections associated with a device that has been converted to the
       system-ram mode. If one or more blocks are already offline, attempt to offline the
       remaining blocks. If all blocks were already offline, print a message and return success
       without actually doing anything.

       This is complementary to the daxctl-online-memory command, and may be used when it is
       wished to offline the memory sections, but not convert the device back to devdax mode.

OPTIONS

       -r, --region=
           Restrict the operation to devices belonging to the specified region(s). A device-dax
           region is a contiguous range of memory that hosts one or more /dev/daxX.Y devices,
           where X is the region id and Y is the device instance id.

       -u, --human
           By default the command will output machine-friendly raw-integer data. Instead, with
           this flag, numbers representing storage size will be formatted as human readable
           strings with units, other fields are converted to hexadecimal strings.

       -v, --verbose
           Emit more debug messages
