What is platform modification?

Platform modification

CAUTION Service Disruption

To avoid a network management outage, it is strongly recommended that you contact technical support before you attempt to modify an NFM-P component platform.

An NFM-P component may require reconfiguration or another type of action in response to a change in the available platform resources.

After you reconfigure the platform of a main server, main database, or auxiliary server station, you must ensure that the station reboots successfully before you restart the NFM-P software on the station.

Basic platform modifications include:

• Number of CPUs

• Amount of RAM

• NIC type

• OS patch or upgrade

• IP-address or hostname change;see the following, as required:

  • How do I change the IP address or hostname of an NFM-P component?

  • How do I change the auxiliary database external IP addresses?

Some components require specific configuration as part of a platform modification; see the following, as required:

• any component, before increasing LVM disk space— How do I test NFM-P disk performance?

• main database, after an OS patch or upgrade— How do I relink the Oracle executable files?

Platform replacement

In the event that an NFM-P component station fails and cannot be recovered, you must re-install the component on a replacement station that has the same platform specifications as the original station. If you want to use a station with different specifications, you must contact technical support to develop an approved hardware migration strategy.

After you replace the platform of an NFM-P component, you must ensure that the newly installed component on the replacement station retains all functions and customized properties of the original component.

Some components, such as main servers, may have custom settings in configuration files. In order to restore the original server functions, you must restore the custom settings. Each NFM-P procedure that describes modifying parameters in configuration files includes a step to back up the current configuration to a secure location. After a replacement component is installed, and before the component initializes, you must use the backup files to replace the newly installed files. Contact technical support for more information.

Multi-vendor driver restoration

MV driver files are installed on a main server after the main server installation. If your NFM-P system manages devices using MV drivers, and the main server fails, you must re-install the drivers on the replacement main server.

Note: Until the MV drivers are installed on the new main server, any devices managed using the drivers are in the Suspended state, and the driver status indicates that the driver file is absent from the main server file system.

See the NSP NFM-P User Guide for driver installation information.
