The NVRAM is divided into two partitions. The first partition, consisting of 1 megabyte (MB), is used
by the existing NVRAM file-system partition. The second partition, consisting of 1 MB, is a raw data
partition and is used by the Kernel Dumper to store reboot historical logs, critical crash information,
syslog, and Kernel Dumper traces. The erase nvram-raw: command formats the raw data partition of
the NVRAM.
