Monitoring an OpenVMS Galaxy with HP Availability Manager  



The Availability Manager software provides a valuable real-time view of the Galaxy system. Availability Manager can monitor all Galaxy instances from a single workstation or PC anywhere on the local area network. Availability Manager utilizes a custom OpenVMS driver (RMDRIVER) that periodically gathers availability data from the system. This information is returned to the Availability Manager Data Analyzer using a low-level Ethernet protocol.

The Data Analyzer provides numerous views and graphs of the system's availability characteristics. Additionally, when Availability Manager detects one of numerous known conditions, it notifies the user and offers a set of solutions (called fixes) that can be applied to resolve the condition.

Every OpenVMS system comes with the Availability Manager Data Collector (RMDRIVER) installed. To enable the collector, you must execute its startup procedure inside SYSTARTUP_VMS.COM or manually on each Galaxy instance you want to monitor. Enter the following commands to start or stop the data collector:

$ @SYS$STARTUP:AMDS$STARTUP START
or:
$ @SYS$STARTUP:AMDS$STARTUP STOP
Before starting the collector, you need to specify a group name for your Galaxy. Do so by editing the SYS$MANAGER:AMDS$LOGICALS.COM file. This file includes a statement for declaring a group name. Choose any unique name, making sure this file on each Galaxy instance contains the same group name.

When using Availability Manager, OpenVMS Engineering finds it useful to display the System Overview window and a CPU Modes Summary Page of the Node Summary Page for each Galaxy instance. There are a number of additional views you can monitor depending on your specific interests. For more information about Availability Manager, see the HP OpenVMS Availibility Manager User's Manual.
