DAXCTL-ONLINE-MEMORY(1)

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.

-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
