# daxctl-offline-memory(1)

Offline the memory for a device that is in system-ram mode

## 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
