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


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


  • Reconfigure dax0.0 to system-ram mode
# daxctl reconfigure-device --mode=system-ram --human dax0.0
  "size":"7.87 GiB (8.45 GB)",
  • Offline the memory
# daxctl offline-memory dax0.0
dax0.0: 62 sections offlined
offlined memory for 1 device


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.


-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
