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.
25

OPTIONS

27       <dimm>
28
29               A 'nmemX' device name, or a dimm id number. The keyword 'all' can
30               be specified to carry out the operation on every dimm in the system,
31               optionally filtered by bus id (see --bus= option).
32
33       -b, --bus=
34           Enforce that the operation only be carried on devices that are
35           attached to the given bus. Where bus can be a provider name or a
36           bus id number.
