Troubleshooting of virtual and physical computer resource conflicts

Products

• IT Management Suite

Issue/Introduction

Managed physical computer fails to communicate and fails to register itself with the SMP (Symantec Management Platform) Server.

A computer resource exists on the SMP server, but its resource type is a virtual computer.

 

 

Environment

ITMS - Any version

Cause

Computer resources can be virtual or physical resource types.

If a managed physical computer is virtualized resource type will be promoted from physical to virtual.

SMP does not allow demoting of virtual to physical computer resource type, though.

In case of conflict (such as a merge scenario) virtual machine overrides the resource type, and the original physical machine fails to recreate and register itself with the SMP server.

Resolution

To find the rogue machine that causes the resource type change, use the attached SQL triggers to help with the investigation. The following should help you to understand what has been used on those triggers:

1. 1. SQL triggers monitor resource tables
      • RM_ResourceComputer
      • RM_ResourceVirtual_Machine
   2. and keep changes in audit tables
      • RM_ResourceComputer_audit
      • RM_ResourceVirtual_Machine_audit
   3. Allowing administrators to find the time stamp when resources are added/deleted, and help find in SMP or IIS logs what triggered the resource type change.

Note:
Some of the most common issues when there is a conflict between resource types are:

Error: Policy request failed, COM error: The specified resource or other object does not exist (0x80041003)
