Hello everybody,
I have few questions about HA.
We have 2 SAN (with LUN replicated) and there are 2 sites (active / active)
site A = 3 ESXi servers
site B = 3 ESXi servers
vSphere 4 Entreprise, vCenter Server 4 standard.vSphere 4.1.
In my society, we have one DataCenter with one cluster including 6 ESXi servers with HA.
One time, I had a problem with one ESXi and I can't reachable the servers on this ESX. Why HA didn't works ?
I believe that HA restarted my vm's. I don't understand.
The HA settings of my cluster are :
- Turn On VMware VMware HA
- Enable Host Monitoring
- Enable : do not power on VM's that violate availabily constraints
- Adminission control Policy : Host failures cluster tolerates : 3
Advanced options : das.bypassNetCompatCheck = true
- Virtual Machine options : VM restart priority = Medium
- Host Isolation response : Leave powered on
- VM Monitoring : Disabled
- Monitoring sensitivity = High (Custom disabled)
The rules in VMware DRS works with HA ?
Because, we have rules to forbidden vm's site A move to site B and rule to forbidden vm's site B move to site A. If Site A is down, my Vm's (Site A) go to Site B (with ressource enought) despite this rules ?
Thanks in advance.
