NAME

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

SYNOPSIS

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

DESCRIPTION

       A generic DIMM device object, named /dev/nmemX, is registered for each memory device
       indicated in the ACPI NFIT table, or other platform NVDIMM resource discovery mechanism.
       The LIBNVDIMM core provides a built-in driver for these DIMM devices. The driver is
       responsible for determining if the DIMM implements a namespace label area, and
       initializing the kernel’s in-memory copy of that label data.

       The kernel performs runtime modifications of that data when namespace provisioning actions
       are taken, and actively blocks userspace from initiating label data changes while the DIMM
       is active in any region. Disabling a DIMM, after all the regions it is a member of have
       been disabled, allows userspace to manually update the label data to be consumed when the
       DIMM is next enabled.

OPTIONS

       <dimm>

               A 'nmemX' device name, or a dimm id number. The keyword 'all' can
               be specified to carry out the operation on every dimm in the system,
               optionally filtered by bus id (see --bus= option).

       -b, --bus=
           Enforce that the operation only be carried on devices that are attached to the given
           bus. Where bus can be a provider name or a bus id number.
