daxctl−online−memory − Online the memory for a device that is in system−ram mode
daxctl online−memory <dax0.0> [<dax1.0>...<daxY.Z>] [<options>]
• 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
• Onlining memory when some sections were already online
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.
−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
