Hi all, I'm now encountering a weird issue that the hosts lost connection persistently. I really need help for this issue. The whole system is mentioned as follows.
ESXi 5.0
2 hosts: HP Proliant DL380G7
iSCSI SAN storage: Netgear ReadyNAS 3100
4 virtual machines are installed separately in the hosts: Database server, Application server, Web server and vcenter server.
When this issue comes, I can see that the vmhba35 is down on both hosts and the hosts lose connections from iSCSI SAN storage. And from the "Recent Tasks", the virtual machines keep resetting by themselves. Though the vSphere shows that the virtual machines are running but I cannot access to them by remote desktop or console. After I reboot the hosts, then the system can run again. I wonder if this is an issue regarding Vmware. Please help! Thanks a lot!
