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

# 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"
}
# 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
