daxctl−offline−memory(1)

NAME

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

• Reconfigure dax0.0 to system−ram mode
# 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"
}
• Offline the memory
# 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
