Mac Id And License Keys; Previous Backups; Upgrades - Hitachi NAS Platform 4000 Series Hardware Reference Manual

To upgrade a model HNAS 4060 to a model HNAS 4080, you add a license. You cannot
upgrade a model HNAS 4060 or model HNAS 4080 to a model HNAS 4100.
In a HNAS 4080 cluster configuration, when the node joins the cluster, the node software
automatically upgrades from HNAS 4060 to HNAS 4080.
The upgrade process is outside the scope of this document and documented separately.
Contact Hitachi Vantara Support Connect 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 Vantara 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.

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.
