expand virtual disk across multiple datastore

Hi Experts,

I have a VM (windows server 2012) with Virtual drive (D) of 12 TB and I've created new data store (14 TB) and would like to expand drive D and add that 14 TB to it.

please advise

Michael

So do you want to create a 12TB + 14TB virtual disk e.g. a total disk size of 26TB ?

e.g. expand the current drive D to 26TB from 12TB ?

because for that purpose, it would have been recommend and better to expand the current datastore, by 14TB, not create a new datastore.

Dell Equallogic volume size is limited to 15TB and hence datastore  is 15TB.

P6210 is the model running out dated FW 7.1.1.

yes 26TB for drive D

Okay, then this becomes a more tricky and is not recommended.

You would need to create a new virtual disk on the new datastore, and then using Disk Management in the OS, create/expand a dynamic disk, and add the new disk to the existing disk.

No beware, if any virtual disk failed or was unavailable, the entire OS disk would fail.

You need to use Disk Management in the OS, and select Add/Expand, and expand across the new disk.
