Swapping components
The server can be replaced onsite, however, some components are not included in your
replacement server. You must remove those components from the original server and
use them in the replacement server. There are a minimum of three parts to be reused in
the replacement server.
The components that can be swapped include:
■
Power supplies
■
Bezel
■
Rack mounting guides
MAC ID and license keys
The replacement server has a new MAC ID, which means that you are required to have
new license keys regardless of whether you are replacing a single node or a complete
cluster.
As part of the field replacement process, Hitachi Vantara recommends that you obtain
temporary keys to enable quick delivery and implementation. However, any temporary
keys 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 an 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, a manual recovery
process is required to re-establish 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.
