If you image a Collector Manager server (for example, by using ZenWorks Imaging) and restore the images on different machines, Sentinel Log Manager does not uniquely identify the new instances of Collector Manager. This happens due to duplicate UUIDs.
You must generate the UUID on the newly installed Collector Manager systems by performing the following steps:
Delete the host.id or sentinel.id file that is located in the /var/opt/novell/sentinel_log_mgr/data folder.
Restart the Collector Manager.
The Collector Manager automatically generates the UUID.
