Hello
We have cluster of 3 ESX servers. Cluster is DRS and HA enabled
When I tried tu put one of servers (number 3) in maintenance mode suddenly durnig migration of VMs, server number 1 was marked disconnected.
VMs on that server are working ok, I can ping it but cannot connect to it using VC or VIC.
And I cant reconnect it.
Has anyone experienced similar behavior? Or knows how to reconnect server?
Regards
Jarek
First thing I would try is:
service mgmt-vmware restart
Either from SSH (if you can connect?) or directly at the console.

Yup ... if you are unable to reconnect to a host then two things might have happened ...
1. Host agent (Hostd) crash.
2. VC unable to install/upgrade VirtualCenter Agent.
For reason 1,
if HostAgent is crashed on ESX Server you can run the command +service mgmt-vmware start +(to start the HostAgent) wait for few seconds and try connecting to VC.
For reason 2,
i. see if there's enough free space on / of ESX server to push/install VirtualCenter Agent.
ii. Check if /tmp/vmware-root directory is present , if it doesn't exist create one and then try connecting to VC.
Hope this resolves the issue.

Restarting mgmt-vmware service helped.
But I have another question. I've noticed that most of work is done by first server in cluster. Weather I'm migrating machine from one host to another, creating template, creating new VM in cluster there's always first server involved. Is it ok?
Your first server is probably your HA Primary Host so that may explain it although it shouldn't be under massive amounts of strain...
