These are the release Notes for the "Intelligent Peripheral Fault Manager 
for Tru64 UNIX" version 2.20

The following features were added in the V2.20 release:

1. New dry contact relays have been added to the indicator module - 
   External alarm signaling devices can now be connected to the Indicator 
   Module. New dry contact relays have been added to the indicator module.  
   These relays	track the states of the alarm LEDs. Connectors, allowing 
   external connections, are located on the rear of the Indicator Panel.  

2. Increased the maximum number of alarms that IPFM can handle from 100 to 2048

3. Changed the IPFM alarm filename convention.   The alarm event history log, 
   found in the /usr/opt/IPFM/log directory will be created each day.  
   Instead of a single log file that continuously grows  a new log file 
   is created at the start of each day.  The name of the log files have 
   the format IPFM_event_log.dd_mmm_yyyy, e.g. IPFM-event_log.01_Apr_1999.

4. Several new options have been added to the ipfm_user_api API routine:
   The ipfm_user_api routine now has the following new options:

	* Set, Clear and Acknowledge Warning messages
	* Set, Clear and Acknowledge Informational messages 
	* Clear all alarms
	* Acknowledge all alarms
	* Re-post all alarms
	* Get the number of outstanding alarms
	* Get the outstanding alarm text

5. New MIB variables to allow an NMS to issue a CLR_ALL (clear all alarms), 
   ACK_ALL (acknowledge all alarms), and REPOST_ALL (re-generate SNMP 
   traps for all outstanding alarms).

6. The audible alarms can now be disabled within the configuration file 
   settings.  Changing the line item "AUDIBLE TRUE" to "AUDIBLE FALSE" within 
   the file /usr/opt/IPFM/bin/online/ipfm.conf will disable audible alarms.

7. The environmental temperature monitoring will use the dynamic variable 
   ENVMON_HIGH_THRESH as the high temperature threshold (if it has been 
   configured using the UNIX envconfig utility).   If this variable has 
   not been set, the read-only high temperature threshold from the serve
   system MIB will be used.

8. A new style SNMP trap has been created for IPFM that is OSI compliant.  Using
   this alarm trap style simplifies the integration of IPFM with TeMIP and other 
   Network Management Systems.   By specifying an environment variable, the 
   SNMP trap style can be changed from the previous trap style to this 
   alternate trap style.

9. The process monitoring example in the ipfm.conf configuration file has 
   been changed. 

10. Fixed a bug in the temperature threshold environmental monitoring that 
    prevented the Alphaserver environmental alarms from being generated.

11. The ipfm_menu has been changed to prevent control characters from 
    becoming embedded in text strings making them unprintable. This occurred 
    when entering alarm text, either the backspace key or the delete key     
    (depending on the terminal emulator). Now, if non ASCII-numeric characters
    are found in the event text, the entry will be rejected, and the user will
    be re-prompted for input.

12. Changed from using /tmp for the IPFM temporary files to using the 
    /usr/opt/IPFM/bin/online directory.

13. If the user specifies any processes to be monitored in the ipfm.conf 
    configuration file, the minimum polling interval will be 3 seconds. 
    The polling interval can be as low as 1 second if the user is not 
    monitoring processes.

14. Fixed a bug with IPFM process monitoring.   If the IFPM process monitor 
    re-started any user process’s, the IPFM driver could not be unloaded 
    (the ipfm_shutdown would fail) until the process that was re-started 
    had been killed.
