Extract Files
-------------
1. From a Linux command shell, change to the directory where the
   perc-apps-A09.tar.gz file was downloaded.
2. Extract the files by typing:

   # tar xvzf perc-apps-A09.tar.gz

   This command will extract the contents of perc-apps-A09.tar.gz
   into the same directory where the downloaded file is located.
   
NOTE: Winzip may not extract the files correctly under Microsoft Windows.   


Install RPM and Configure Agent
-------------------------------

NOTE: Please make sure net-snmp version 5.0 or above is installed before
      installing PERCSNMP.
      
Uninstall earlier versions of PERCSNMP before installing a newer version.

To install the PERCSNMP package, type the following from the directory
where the RPM is located:

# rpm -ihv percsnmp-5.04-2.i386.rpm


Make necessary changes for the DELL PERC agent in snmpd.conf by 
refering to the sample file "/etc/snmp/percsnmpd.conf".  

NOTE:
If there is no configuration file snmpd.conf in /etc/snmp then, search for 
snmpd.conf file in /usr/share/snmp or /usr/local/share/snmp. If the file exists 
in any one of the above directories, modify the corresponding configuration file.
The agent will be started at boot time or may be started and stopped manually
by typing:

# service percsnmpd start/stop

The agent will generate traps to the destinations given in the configuration file
/etc/percsnmp/percsnmptrap.conf if any megaraid change of state occurs.


Uninstall RPM
-------------
To uninstall the PERCSNMP RPM:

# rpm -e percsnmp


Files included in this release:
-------------------------------

Fixes and Enhancements
======================

perc-apps-A09
-------------
Removed LinFlash, MegaMon, and Dellmgr applications from the perc-apps download
package. If needed, Dell OpenManage software should be utilized as it provides
expanded RAID management functionality.


PercSNMP 5.04-2
---------------
1. Battery status trap has been added.
2. Addressed issue where SNMP reports Check Consistency while BGI is running.
3. Security update to prevent file creation when reading version information.
4. Updated startup script permissions to allow agent to start after reboot.
5. Physical drive size is now reported properly.


Version History
===============
                                                 
PercSNMP 4.10a-1
----------------
1. During the startup the S55percagent script reported execution permission denied
   exception. The S55percsnmp script was not built in rpm with execution permission.
2. Traps were not generated when the community is other than public. Previously the
   public string was hard coded and hence what ever the type of community string in
   the configuration file it was displayed as public, now the actual community string
   read from the configuration file is given to generate the traps. A private community
   entry shall be added in the configuration file and the generated traps may be observed.
