DAXCTL-OFFLINE-MEMORY(1)         daxctl Manual        DAXCTL-OFFLINE-MEMORY(1)

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
       o   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"
           }

       o   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
