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.
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.
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.
