Upgrades
Replacement servers can be down or above a revision, and not at the
expected level of firmware required at the customer site. An upgrade is
typically required during the replacement process, which is not covered in
this document. It is assumed that all services personnel performing a
replacement have already been trained, and know where to get this
information within their respective organization.
Replacing a single server with an embedded SMU
If a single server with an embedded SMU is non-functioning, 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, these files can 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.
