Replacing a single server with an external SMU
Note that if it is a single server with an external SMU that is 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.
Note: Replacement servers are shipped without an embedded system
management unit (SMU), so you must have a SMU installed before you can
connect to a standalone server.
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.
