Replacing all servers within a cluster

NAS Platform and Unified Storage Series 4000 Hardware Reference

Part Number

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.
