[ESXi 4.1] ASH Script to Gracefully Shutdown VM's

Hello,

I have the following script I'm working on. Its purpose is to gracefully shutdown critical VM's in case I need to perform work... one script to rule them all.

#! /bin/ash

echo "=================================================="

echo "Gracefully shutting down critical virtual machines"

echo "=================================================="

echo

if [ "$HOSTNAME" == "esx01" ]; then

  echo "Shutting down VMs on ESX01"

   vim-cmd vmsvc/power.shutdown 4816

   vim-cmd vmsvc/power.shutdown 5456

   vim-cmd vmsvc/power.shutdown 3392

   vim-cmd vmsvc/power.shutdown 5248

   vim-cmd vmsvc/power.shutdown 6000

  echo "Done."

 

elif [ "$HOSTNAME" == "esx02" ]; then

  echo "Shutting down VMs on ESX02..."

   vim-cmd vmsvc/power.shutdown 352

   vim-cmd vmsvc/power.shutdown 368

   vim-cmd vmsvc/power.shutdown 512

   vim-cmd vmsvc/power.shutdown 528

   vim-cmd vmsvc/power.shutdown 592

  echo "Done."

else

  echo "No machines were shutdown."

fi

I had thought that $HOSTNAME was the environment variable with the name of the host server. Evidently, this isn't the case.

How can I determine the HOSTNAME so I can have one script that would be able to be used on several servers to shutdown the proper VM's?

Thanks,

Johnathan
