NAME

6       ndctl-disable-dimm - disable one or more idle dimms

SYNOPSIS

9       ndctl disable-dimm <dimm> [<options>]

DESCRIPTION

12       A generic DIMM device object, named /dev/nmemX, is registered for each
13       memory device indicated in the ACPI NFIT table, or other platform
14       NVDIMM resource discovery mechanism. The LIBNVDIMM core provides a
15       built-in driver for these DIMM devices. The driver is responsible for
16       determining if the DIMM implements a namespace label area, and
17       initializing the kernel’s in-memory copy of that label data.
18
19       The kernel performs runtime modifications of that data when namespace
20       provisioning actions are taken, and actively blocks userspace from
21       initiating label data changes while the DIMM is active in any region.
22       Disabling a DIMM, after all the regions it is a member of have been
23       disabled, allows userspace to manually update the label data to be
24       consumed when the DIMM is next enabled.

OPTIONS

27       <dimm>
28           A nmemX device name, or a dimm id number. Restrict the operation to
29           the specified dimm(s). The keyword all can be specified to indicate
30           the lack of any restriction, however this is the same as not
31           supplying a --dimm option at all.
32
33       -b, --bus=
34           A bus id number, or a provider string (e.g. "ACPI.NFIT"). Restrict
35           the operation to the specified bus(es). The keyword all can be
36           specified to indicate the lack of any restriction, however this is
37           the same as not supplying a --bus option at all.
