Since I enabled alarms in VirtualCenter on 10/07/2008 we have encountered 14 seperate false alarms regarding host connectivity.
Here’s the alarm:
Old Status: Green
New Status: Red
Host connection state – (State = Not responding)
Alarm: Host connection state
([Red State Is Equal To notResponding])
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.
