Hello

I'm constructing 5ESX+a vCenter serv. I'm testing FT on the system.

Today vCenter OS (W2008) demanded system reboot. After rebooting vCenter Serv. All of ESX hosts have alert icon. end indicate "not responding"

I tried to connect ESX (version 4) hosts to vCenter again. Once they came back normally, but after few seconds ,They turned red again. All of them have ping connection to vCenter serv.

There are no red messages in Tusks and events. Two messages are found in Summary of Cluster ·There aren't sufficient resource for HA failover. ·Can't contact primary HA agent.

I'm also not able to reset FT configuration because all of VMS aren't accessed from vCenter

What should I do?

What kind of storage do people actually use for VMware ESX servers?

as seen on Server Fault - Search for 'Server Fault'
VMware and many network evangelists try to tell you that sophisticated (=expensive) fiber SANs are the "only" storage option for VMware ESX and ESXi servers. Well, yes, of course. Using a SAN is fast, reliable and makes vMotion possible. Great. But: Can all ESX/ESXi users really afford SANs? My theory… >>> More
