Building a cluster and HA

Hi,

I have several questions but first a little overview of my systems.
I'm using ESXi 5.0 on 2 IBM x3650 M3 connected to IBM N3300/NetApp FAS2020-a20 FC storage system.
I plan to build a cluster with this machines and store the VMs on the storage. On the every host I have 4x2.5'' 10k HDD in RAID10

1Q: Is it possible to have same VM files on the storage and on the local drives, VM running from the storage and if storage system fail VM start automaticly from local drives.

2Q: I've already build a cluster, but when I restart one of the hosts ( simulating a case of failure ) the VM change host but VM freeze and restart automatic.

It is possible to have same files on storage and on the local drives but they won't be in synch automatically. Also if there is no automatic failover of VM from storage to local drive

2Q: I've already build a cluster, but when I restart one of the hosts ( simulating a case of failure ) the VM change host but VM freeze and restart automatic.


This is expected behaviour from HA. If you want to check if the vMotion is successful put the host into maintenance mode and check if VM's can automatically move to other hosts.

With Great Regards,

No, I try HA by unplunging one of power suplies, but nothing happens, just it triggert an alert and it was all... no migrating VMs, no maintance on the fail host, nothing... just an alert.

unplugging a redundant power supply is not going to generate an HA event, if that is what you are trying to do.  If you want to generate an HA event, the easiest way would be to reboot the Host, or pull the power cables.
