Dear community,
I had a problem with set up network redunancy. I am looking for your help.
we have 4 ESXi servers with version 5.0 installed. everything working fine.
Hardware from HCL (Dell PEM710HD)
Each server haves 4 NICs. NICs #3 and #4 are designed for managent purposes.
yeasterday I installed lastes 5.1 on one of servers.
I configure NICs #3 and #4 as management adapters and assign IP address.
A am able ping management IP wihtout problem.
But vShere client and vCenter cannot connect to this server.
After series of expirements, I found, if I use only NIC #3 - I am able to connect.
If I use NIC 4 (in combination or standalone) - no way to manage server.
in any case I am able to ping ESXi server without any problem.
I restarted management network, reboot server, restart managment agents -it is not helps.
NICs 3 & 4 are connected to separate switches (Dell power connect modular for DELL PE1000 chassiss) and then both switches connected into core router/switch (Cisco c6500 series). Ports are in access mode and in correct VLAN.
From point of Cisco - I see right MAC addresses and correct paths (VLANs, uplink, etc)
I am sure, for there is no networking problem, since ping are working well.
If somebody able to suggest where is error - please let me know.
PS: I installed ESxi many times (includes ESXi5.1) - no such problem appears.
