During Maintenance mode, the DR4000 system determines, detects, and
repairs the data loss. During the system reboot process, it ensures that no
valuable data remains on the NVRAM.
NVRAM Field Replacement

procedure is observed:
1
Verify that the DR4000 system software detects the NVRAM as new to the
system.
2
Enter the following DR4000 system CLI command:
maintenance --hardware --reinit_nvram
This command initializes the NVRAM, creates new partitions, and
updates information used internally by the DR4000 system software.
3
Verify that the DR4000 system enters its Maintenance mode.
If properly initialized, the DR4000 system enters its Maintenance mode.
The filesystem checker examines every blockmap and datastore to
determine how much data was lost due to the failed NVRAM.
