HP-AMS keeps restarting

Problem

A few weeks ago we started to deploy HP Custom Image for ESXi 5.1.0 Update 2 on all our ESXi hosts. Everything seemed to work without problems until a colleague recently discovered in the logfiles that the HP-AMS provider keeps restarting every 5 minutes and gives an error message that it can’t start because it only works on.

We also noticed the problem only occured on ESXi hosts which are not HP DL380Gen8. So DL585 G5,G6,G7 gave these errors. Makes sense, the error also notices that it runs on Gen8 and older!

Solution

Luckily I found a VMWare article KB2085618 which described our problem:

Too bad the only solution is to remove the Agentless Management agent…by hand on the command line on 50+ ESXi hosts.

Damn! I was too lame to do this by hand so build a little powerCLI script. It’s not completed yet or error free. It was just a quick and dirty solution for fast results. So it’s not yet completed, but would like to share it already as it is faster then enabling SSH everywhere, connecting to ESXi hosts, insert commands, reboot etc.

Script

Pre-requirements

– Connect to your vCenter

– Put host in maintenance mode

– Load the module of function

– Plink installed and edited the script to use the right Plink directory

These functions were still in my profile so I put them on the site but were not created by me, these are only needed to enable/disable SSH.

Switches

-status : Checks the status of the host, is the agent installed and which model is the host.

-remove : Checks if host is in maintenance mode, stops the HP-AMS service, uninstalls the HP-AMS service and restarts the VMhost
