NAME¶
daxctl-offline-memory - Offline the memory for a device that is in system-ram modeSYNOPSIS¶
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
