Issue/Introduction
Resolution
Merging is based on resource key names and values. Typical causes of merging are:
- Common mac addresses from virtualization software or other predefined NICS
- DNS cache providing the wrong computer name from stale leases
- Common resource key names and values, which are used to identify unique computer resources
- Computers with the same hostname, usually from imaging processes
- Other causes may exist
Step 1: Identify common resource keyname and keyvalue values on Unix, Linux and Mac managed computers:
Run the following command on two or more computers and compare the name/value pairs. If any name/value pair matches on two or more computers, the computer resources will merge on the NS server.
- aex-helper info resource
Sample output:
# aex-helper info resource
Resource GUID: {ECBCB670-E433-4870-8B53-DF6E8266092B}
Resource Type: Computer ({493435F7-3B17-4C4C-B07F-C23E7AB7781F})
Resource keys:
name.domain=mycomputer
name.domain=mycomputer.mydomain
fqdn=mycomputer.mydomain.com
name.domain=mycomputer.mydomain.net
