NAME

       daxctl-online-memory - Online the memory for a device that is in system-ram mode

SYNOPSIS

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

EXAMPLES

       •   Reconfigure dax0.0 to system-ram mode, don’t online the memory

           # daxctl reconfigure-device --mode=system-ram --no-online --human dax0.0
           {
             "chardev":"dax0.0",
             "size":"7.87 GiB (8.45 GB)",
             "target_node":2,
             "mode":"system-ram"
           }

       •   Online the memory separately

           # daxctl online-memory dax0.0
           dax0.0: 62 new sections onlined
           onlined memory for 1 device

       •   Onlining memory when some sections were already online

           # daxctl online-memory dax0.0
           dax0.0: 1 section already online
           dax0.0: 61 new sections onlined
           onlined memory for 1 device

DESCRIPTION

       Online the memory sections associated with a device that has been converted to the
       system-ram mode. If one or more blocks are already online, print a message about them, and
       attempt to online the remaining blocks.

       This is complementary to the daxctl-reconfigure-device command, when used with the
       --no-online option to skip onlining memory sections immediately after the reconfigure. In
       these scenarios, the memory can be onlined at a later time using daxctl-online-memory.

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.

       --no-movable
           --movable is the default. This can be overridden to online new memory such that it is
           not movable. This allows any allocation to potentially be served from this memory.
           This may preclude subsequent removal. With the --movable behavior (which is default),
           kernel allocations will not consider this memory, and it will be reserved for
           application use.

       -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
