Shutdown vs. Power Off in vCloud Director vApps.
vCloud Director is a great tool, but I feel like some
people aren’t always using it in the precise way that it was designed. When you want to perform maintenance on a VM
that vCD manages, you’re probably going to have to have that VM powered
down. So, what do you do? You open your vApp, right click on your VM
and select Power Off, right? Well, I’ve
seen a lot of people do just that, but it’s not really what I’d recommend. Remember, Power Off is not Shutdown; it’s
just going to perform a hard power off and your VM might have some issues after that.
So, what do you do?
There’s no “Shutdown” option on that Right Click menu in vCD.
Since you want to keep your servers in tip-top shape, you open the VM
console and then issue a command inside the guest OS (good ole “shutdown /s”
anyone?). The VM goes down gracefully
and you can now manage it… but the vApp might be in an interesting state: “partially
running” which can prevent you from changing some of its settings (even if that VM was
the only one in the vApp). From here,
you can select the vApp itself and press that big red “stop” button in order to
fully power off the vApp for maintenance on it.
Why not do that from the first place, you ask? Well, that might be a good solution,
especially after you tweak some settings.
By default, that “Stop” button performs a “Power Off” operation on all
VMs in the vApp. In my experience, that’s
not very useful. Fortunately, it can be
changed.
If you Right Click on the vApp (not a VM within it, but the
vApp itself), you can select Properties
and then go to the Starting and Stopping
VMs tab. From there, it’s pretty
self-explanatory. Just change the Stop Action for each VM from Power Off (default) to Shutdown. Now, if you need a hard power function, you
can still target individual VMs within the vApp, but for general shutdown
purposes, you can easily perform soft power functions. As an added benefit, while you’re in there,
you can set the order for those power operations in order to ensure that things
work smoothly!
