I have been testing an ESX 2.5 host with VI Client 2.5.
I had been able to Shutdown and Restart the host via the client fine. Now after importing some guests the Shutdown and Reboot options for the host are dimmed in the client. I can't shutdown or reboot the host.
The guests are shutdown....
Also, let me know if this type of question should go to another board.
Sorry, it is ESX 3.5 viewed via VIC 2.5.
I ended up hitting the reset button on the ESX box and when it came back up I was able to access the Shutdown and Reboot menu items. Weird.
I had used VMware Converter to bring guests into the host.
probably your machine stuck in shutdown,
you can check machine state in service console and manually shutdown machine if it happens again or just to check machine state
Connect to ESX server with Putty
o Check VM state by typing vmware-cmd /<path to VM directory>/server.vmx getstate
o Type ps -eaf | grep <virtualmachinename>
you will see all proceses assosiated with that machine and you can kill process.
o Type kill -9 <pid>
o Check VM state again, it should now be off
o Type vmware-cmd /<path to VM directory>/server.vmx start to power on VM
