How to Restart Management agents in ESXi Using ESXi Shell or Secure Shell (SSH)

How to Restart Management agents in ESXi Using ESXi Shell or Secure Shell (SSH).

Restart the ESXi host daemon and vCenter Agent services using these commands:

/etc/init.d/hostd restart

/etc/init.d/vpxa restart

To reset the management network on a specific VMkernel interface, by default vmk0, run the command:esxcli network ip interface set -e false -i vmk0; esxcli network ip interface set -e true -i vmk0
Note: Using a semicolon (;) between the two commands ensures the VMkernel interface is disabled and then re-enabled in succession. If the management interface is not running on vmk0, change the above command according to the VMkernel interface used.
To restart all management agents on the host, run the command:services.sh restart
