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. Restrict the operation to the specified dimm(s). The
           keyword all can be specified to indicate the lack of any restriction, however this is the same as not
           supplying a --dimm option at all.

       -b, --bus=
           A bus id number, or a provider string (e.g. "ACPI.NFIT"). Restrict the operation to the specified
           bus(es). The keyword all can be specified to indicate the lack of any restriction, however this is
           the same as not supplying a --bus option at all.
