ESX was installed to the same disks that are being used for the data store that virtual machines are installed on.  Theses disk are now out of space and can no longer support new vm's.   Do I simply replace the disks and reinstall ESX then restore the vm's from backup?

That's correct.

Unless you have a Smart Storage Controller, that will allow you to expand the current RAID array using these new disks.

The problem is there are no slots left over to add new disks so all of them need to be replaced.  If ESX was installed to a flash drive instead, would I have been able to vm's to a new data store and continue to use the same host, then replace the drives and create a new data store, then move the vm's back?

Yes, that's why we always recommend to install ESXi on USB flash drives and SD cards, and hence why we have been doing it since 2004!

It's always best to seperate OS and Datastore using flash media and hard disks for datastore.

How can I identify where ESX is installed at?  If I browse the data store will I see the install files?>
