VMWare ESX host gets disconnected.

Sometime your ESX host keeps disconnecting, so this seems to help, remove it from your virtual center. then run the following commands. Then add it again.

check the version of the Virtual Center Agent:

[root@ESX3 root]# rpm -qa grep vpxa

VMware-vpxa-2.0.1-32042

To stop mgmt-vmware:

[root@ESX3 root]# service mgmt-vmware stop

Stopping VMware ESX Server Management services:

VMware ESX Server Host Agent Services [ OK ]

VMware ESX Server Host Agent Watchdog [ OK ]

VMware ESX Server Host Agent [ OK ]

To stop vpxa:

[root@ESX3 root]# /etc/init.d/vmware-vpxa stop

Stopping vmware-vpxa: [ OK ]

Uninstall vpxa:

[root@ESX3 root]# rpm -e VMware-vpxa-2.0.1-32042

Stopping vmware-vpxa: [ OK ]

warning: /etc/vmware/vpxa.cfg saved as /etc/vmware/vpxa.cfg.rpmsave

To make sure vpxa is no longer there:

[root@ESX3 root]# rpm -qa grep vpxa

[root@ESX3 root]# rpm -qa grep vpx

Restart up mgmt-vmware service:

[root@ESX3 root]# service mgmt-vmware start
