If the server is online, using Web Manager (SMU GUI), navigate to Home
> Server Settings > Configuration Backup & Restore, click backup,
and then select a location to save the backup file.
Ensure you save the backup file to a safe location off platform so that
you can access it after the storage system is offline.
The backup process performed by the embedded SMU will automatically
capture both the SMU and server configuration files in one complete set.
Navigate to Home > Status & Monitoring > Diagnostics Download
to download the diagnostic test results.
Navigate to Home > Server Settings > Firmware Package
Management to verify the existing server (SU) firmware release level.
The new server firmware version must match the failed server;
otherwise, the server cannot properly restore from the backup file. See
the release notes and the system installation guide for release-specific
requirements.
