NSP auxiliary database installation workflow

Description

CAUTION Deployment Requirement

An NSP auxiliary database requires one or more dedicated stations.

You cannot install the auxiliary database software on a station if another NSP system component is installed on the station.

This section describes how to install and enable an NSP auxiliary database in a new or existing NSP deployment; see Workflow for NSP auxiliary database installation

Note: You must set CPU frequency scaling to “performance” in the BIOS of each auxiliary database station, or the auxiliary database installation fails. See the RHEL power management documentation for information about enabling the “performance” CPU frequency scaling governor on a station.

Setting CPU frequency scaling to “performance” effectively disables the function, so may result in greater energy consumption by a station.

Workflow for NSP auxiliary database installation

The following is the sequence of high-level actions required to install and enable an NSP auxiliary database. You can use the workflow and associated procedures to deploy a standalone auxiliary database cluster in one data center, or geo-redundant auxiliary database clusters in separate data centers.

Stages
1	Perform the following sequence of procedures in the standalone or primary data center. Perform procedure To prepare a station for NSP auxiliary database installation on each auxiliary database station. Perform procedure To install the NSP auxiliary database software. Perform procedure To add an NSP auxiliary database to the NSP.
2	If you are deploying a geo-redundant auxiliary database, perform the following sequence of actions in the standby data center. Stop the standby NSP auxiliary database cluster. Perform procedure To prepare a station for NSP auxiliary database installation on each auxiliary database station. Perform procedure To install the NSP auxiliary database software. Perform procedure To add an NSP auxiliary database to the NSP.
