Cause

This issue occurs when you use an older HP Customized VMware image to update any HP ProLiant G5, G6 or G7 servers running VMware ESXi 5.0, 5.1 or 5.5. These models cause the HP Agentless Management Service (AMS), Versions 9.5, 9.6 or 10.0 to make continuous restart attempts and potentially fill up syslog with this message:

root: hp-ams-wd: Detected one or more hpHelper process(es) have stopped running. Restarting...

root: hp-ams stop service...

root: hp-ams-wd: hp-ams start...

root: hp-ams start service...

hpHelper[15106]: hp-ams ver 9.5.0-26: System Product Name is ProLiant BL460c G6.

hpHelper[15106]: hp-ams ver 9.5.0-26: This program will only run on HP ProLiant Gen8 or newer platforms.

 

Currently, HP AMS is only supported on ProLiant Gen8 (or later) hosts.

Resolution

To resolve this issue, remove the hp-ams package from the affected ESXi hosts and replace it with the latest version, 10.1.0 or later. Alternatively, you may reinstall ESXi from the latest HP Customized ESXi Images dated March 2015 or later.

   /etc/init.d/hp-ams.sh stop
   
   Note: If it is in the process of stopping, press CTRL+Cto stop the current process.
    
4. Run this command to remove the the HP Agentless Management Service:
   
   esxcli software vib remove -n hp-ams
