.SH "DESCRIPTION"
.sp
For the NVMe device given, sends a capacity management command to configure/create/delete the Endurance Groups or NVM Sets with the requested operation and element_id\&. On success, if the Operation is Create Endurance group or NVM Set, CQE CDW0 contains Created element identifier else CQE CDW0 is reserved\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
