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.

Select the node from the Preferred Cluster Node list, and then click
apply.
Navigate to Home > Status & Monitoring > Event Logs, and then
click Clear Event Logs.
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.
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.
