Since I enabled alarms in VirtualCenter on 10/07/2008 we have encountered 14 seperate false alarms regarding host connectivity.
Here’s the alarm:
Target: hostname.goes.here
Old Status: Green New Status: Red
Current value: Host connection state - (State = Not responding)
Alarm: Host connection state ([Red State Is Equal To notResponding])
Description: Alarm Host connection state on hostname.goes.here changed from Green to Red
Here’s what we went through with support.
- Sending Diagnostics from VC
- Found out we are running an unsupported HBA (QLA4010’s are not supported in ESX 3.5, but in ESX 3) … this was frustrating because we have seen that they will work with ESX 3.5 elsewhere from VMware
- Advised to up the Service Console RAM to 800 MB from 272 MB
We haven’t been seeing false alarms since.
