Question about HA

$
0
0

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.
