NAME

6       daxctl-offline-memory - Offline the memory for a device that is in
7       system-ram mode
8

SYNOPSIS

10       daxctl offline-memory <dax0.0> [<dax1.0>...<daxY.Z>] [<options>]
11

EXAMPLES

13       ·   Reconfigure dax0.0 to system-ram mode
14
15           # daxctl reconfigure-device --mode=system-ram --human dax0.0
16           {
17             "chardev":"dax0.0",
18             "size":"7.87 GiB (8.45 GB)",
19             "target_node":2,
20             "mode":"system-ram"
21           }
22
23       ·   Offline the memory
24
25           # daxctl offline-memory dax0.0
26           dax0.0: 62 sections offlined
27           offlined memory for 1 device
28

DESCRIPTION

30       Offline the memory sections associated with a device that has been
31       converted to the system-ram mode. If one or more blocks are already
32       offline, attempt to offline the remaining blocks. If all blocks were
33       already offline, print a message and return success without actually
34       doing anything.
35
36       This is complementary to the daxctl-online-memory command, and may be
37       used when it is wished to offline the memory sections, but not convert
38       the device back to devdax mode.
39

OPTIONS

41       -r, --region=
42           Restrict the operation to devices belonging to the specified
43           region(s). A device-dax region is a contiguous range of memory that
44           hosts one or more /dev/daxX.Y devices, where X is the region id and
45           Y is the device instance id.
46
47       -u, --human
48           By default the command will output machine-friendly raw-integer
49           data. Instead, with this flag, numbers representing storage size
50           will be formatted as human readable strings with units, other
51           fields are converted to hexadecimal strings.
52
53       -v, --verbose
54           Emit more debug messages
