I'm taking the "VMware vSphere: Install, Manage, Configure" class for 5.0. When I looked at the alarm definitions, I noticed that the "Unmanaged workload detected on SIOC-enabled datastore"alarm icon has a red X on it. (See attached file.) This was the only icon with a red X that I can find, and my instructor didn't know what it meant. Anyone have an idea? Thanks.
There are a few scenarios described here which might be triggering the alert - http://kb.vmware.com/kb/1020651. Given that it is a training environment, perhaps an unmanaged host has access to the LUN.
Note that this is the alert definition, not an alarm that's being triggered. I'm wondering if it means that the alert cannot be used in my environment, but that seems a bit far-fetched.
