The time required to rebuild the RAID array depends on the workload on the system. On an
idle system, the rebuild might be complete within 30 minutes.
To change the RAID level to RAID 0, run the following command:
$ sudo configure_raid_array.py -m raid0
To confirm that the RAID level was changed as required, run the lsblk command. The entry
in the TYPE column for each SSD in the RAID array indicates the RAID level of the array.

Configuring Support for Custom Drive
Partitioning
DGX A100 systems incorporate data drives configured as RAID 0 by default. You can alter the
default configuration by adding or removing drives, or by switching between a RAID 0
configuration and a RAID 5 configuration. If you alter the default configuration, you must let
NVSM know so that the utility does not flag the configuration as an error, and so that NVSM
can continue to monitor the health of the drives.
To configure NVSM to support a custom drive partitioning perform the following.
Edit /etc/nvsm/nvsm.config and set the use_standard_config_storage parameter to false.
1.
"use_standard_config_storage":false
Restart NVSM.
2.
$ systemctl restart nvsm
Remember to set the parameter back to true if you restore the drive partition back to the
default configuration.
