Experiencing issues connecting to an ESXi host from vCenter Server?

A good place to start your troubleshooting is by restarting the ESXi management agents.

The following method uses the CLI option SSH/Local console to restart an ESXi host management agents:

/etc/init.d/hostd restart
/etc/init.d/vpxa restart

 To restart all management agents on the host, run the command:

services.sh restart

View a list of all management agents restarted as part of the ‘services.sh restart’ cmd:

chkconfig --io

[root@ESXi01:~] chkconfig --io

Confirm what agents are running:

chkconfig --list

[root@ESXi01:~] chkconfig --list

  1. Dave have you run into any issues when restarting the mgmt agents on VSAN?

    I know there is a KB describing issues if VSAN is in a LACP config but I seem to recall it causing additional issues even when it was not. Essentially the backend LSOM components have trouble communicating and ive seen erradict behavior. Just curious on your take.

  2. apparently the ESXi 6.0 command is with two dashes
    e.g. # chkconfig –list

    but just because it shows the agent as ‘running’ or “on” to be exact does not mean its working

    I did the chkconfigr –list output to show hostd and vpxa both on….but if you run a /etc/init.d/hostd status or vpxd status both tell you the hostd is NOT running
