8. Confirm all final settings, IP addresses, customer contact information, service
restarts, client access, and that customer expectations are all in place. Features such
as replication and data migration should all be confirmed as working, and all file
systems and storage pools should be online.
Replacing all servers within a cluster
If both servers with an external SMU that are nonfunctioning, and does not have a recent
backup saved off platform, then a challenging and manual recovery process is necessary.
If this circumstance is encountered, call the support organization for a copy of the
system's latest diagnostics files, if available, to be used as a guide in reestablishing the
system manually. The data and file systems will remain intact independent of the
replacement and without a backup.
Important: Set expectations up front with the customer that this will delay
time to recovery, and that some aspects of the systems configuration might
never be recovered.
Obtaining backups, diagnostics, firmware levels, and license keys
On the old server:
Procedure
1. If the server is online, using NAS Manager, 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.
2. Navigate to Home > Status & Monitoring > Diagnostics download to download
the diagnostic test results.
