Hello all, I would like to discuss a problem that I encountered.

Configuration:

2x HP Proliant DL360 Gen8 / 112GB RAM / HBA HP H221 (Cluster)

1x HP MSA P2000 G3

ESXi version 5.1 Update2 HP Customized

Vcenter 5.1 Update2 (virtual appliance)

Everything supported firmware / bios versions up to date.

Both servers have 2paths to datastore. Only one LUN is provisioned to esx servers.

After istalling esxi on both servers I have deployed vcenter appliance, builded ha cluster and deployed some VMs everithing works perfectly.

After cca 1 week one server lost both paths to datastore (MSA). After restart host everything works like before few days and problem occures again.

I noticed, that failed host (lost datastore) is allways one on witch vcenter appliance is running. The worst thing is, ha agent not restarts vms on another host untill I physically turn that host off.

Workaround was, I reinstall vcenter on third host that is not part of the cluster, only member of datacenter and has only local storage (not msa).

Are you kidding me vmware ?
