OVNM 5.3 - Operations Agent for NonStop Installation Guide

Upgrading OVNM on HP NonStop Server 46
4 Upgrading OVNM on HP NonStop Server
4-1 Considerations while Upgrading OVNM
It is not mandatory to initially upgrade all NonStop Servers to the latest release. Operation Manager Servers can
manage NonStop Servers running either OVNM 4.x or OVNM 5.x Agents.
There are however new features and functions that are only supported on NonStop Servers running OVNM 5.x
Agents.
• Object Configuration Client
OVNM 5.x release introduced the following new features that are not supported on NonStop Servers
running OVNM 4.x or earlier versions.
• Automated Action: In addition to the ability to specify user-written TACL routines to execute, OVNM 5.x
provides the ability to use pre-canned recoveries for many of the thresholds. Most of these recoveries
will use a SPI interface instead of TACL code to perform the recovery.
• EMS Burst Suppression: The new EMS burst suppression (part of OCC) cannot be used with an old
backend as the code only exists in version 5.x.
• Add Object to an Existing Threshold: Use of this feature should be limited to 5.x environments only since
the structure of the message has changed significantly to support wildcards and manager name data.
OCC will not send the request of wildcard objects to the old backend.
• DNS support: Versions of OVNM prior to 5.x will not support DNS names, so you will still need to use
actual IP addresses in the Host Installation Client for those environments.
• Multiple Backend Environments on a Single HP NonStop: Multiple OVNM Nonstop Host Agent
environments on a single HP NonStop
• New Object Threshold
When adding new thresholds, OVNM will not allow you to enter the thresholds that are not supported by
the version of the backend that is currently installed on that particular HP NonStop. If you want to see what
the new thresholds are, review the softdocs and/or Release Notes.
Limitations while working with thresholds that were added in the previous release and are no longer supported
by 5.x
• The thresholds created with OVNM 4.x that have been deleted in 5.x will show the Threshold Name as
Unknown in the Threshold pane of the OVNM Object Configuration Client.

• Modification of thresholds and objects will not be possible, but these can be deleted.
