Model selection

The software for all server models is pre-loaded on the replacement server
before it is shipped from either the factory or depot location.
If for any reason the model selection does not match that which is required
for replacement, then an upgrade process may be required in the field.
The upgrade process is outside the scope of this document and documented
separately. Contact Hitachi Data Systems Support Center for upgrade
information.

MAC ID and license keys

The replacement server will have a new MAC ID. The new ID forces the need
for new license keys regardless whether it is a single node or complete
cluster replacement.
As part of a field replacement process, Hitachi Data Systems recommends
that temporary keys be obtained to enable quick delivery and
implementation. However, any temporary keys used must eventually be
replaced with a permanent key. This is required for all field scenarios, except
when replacing a single node in a cluster.
Note: If the scenario is a single node or all cluster node replacement, use the
span-allow-access command to attach the storage when the MAC ID
changes.

Previous backups

A system backup preserves two critical components of information:
• SMU configuration
• Server configuration
The backup form for an embedded SMU is different than one from an external
SMU. Depending on the replacement scenario severity, different limitations
might exist for the system recovery.
Important: It is assumed that customers are frequently establishing
backups somewhere safely off the platform for recovery purposes. If there is
no backup, and the system to be replaced is nonfunctional, then a manual
recovery process is required to reestablish a functional system. The duration
of this manual recovery is directly related to the complexity of the original
configuration. All data and file systems are preserved independent of a
backup.
