I have " ESXi 5.0 U3 HP Customized" installed on HP DL580 G7 Servers.
my vCenter version is 5.0 U1
Every 2 or 3 days around 12:00 to 1:00 AM (Midnight), one of the hosts, (Almost randomly) disconnects from vCenter, the ping of the host is available, the VMs are ok, and after about 10 minutes it gets connected again automatically.
I actually haven't checked if I could connect directly to the host via VI Client or not?
There is no special event in vCenter Events at the moment that hosts gets disconnected.
Could any body help on this issue?
It seems it is happening after upgrading to ESXi 5.0 U3 from ESXi 5.0 U1... but I am not sure, I am also gonna upgrade vCenter to version 5.0 U3. but I am not sure if it will solve the problem, as U1 is also in interoperability matrix with ESXi 5.0 U3.
