2 different and separate array controllers
2 different non-attached storage arrays
3 blade servers
blade 1 + blade 2 is attached to both storage arrays and to both array controllers. So blade 1 and 2 can see everything
Blade 3 is only attached to 1 of the storage array and 1 array controller. Blade 3 can only see one storage array
Now as far as I could tell I was told that you can't migrate or move vmdk files from 1 datastore to another different datastore. i thought that meant that the "datastore holding the vmdk files" had to be on the same storage array (terabyte array split into into 2 logical drives and present to the esx hosts as datastore) if i wanted to migrate VMDK files.
But storage vmotion appears to work, and it appears that I can migrate my vmdk files from storage array A to storage array B without any issues. Even though both physical arrays are not connected and can not see each other.
Am i missing something? Is it possible to migrate VMDK files from 1 storage array to a different one as long as the Host can see both physical storage devices?
So what happen to
