And this was a datastore at some point? In other words, did someone create a VMFS datastore out of that disk?

[feroz201110141]

Yes right, it was created after vm installed, to add more data storage. D drive.

D drive? not sure I am following this.

If you click the device, do you see partitions?

[feroz201110141]

If you click the device, do you see partitions?

No, click on the disk, see if there are partitions on that disk.

So that 3.8TB device doesn't have a VMFS volume on it.

Did you somehow add the device as a "raw device mapping" to the VM? (Which I doubt, but who knows)

[feroz201110141]

yes, after i configured everything (ads server), later i decide to add another disk which 3.5 tb hdd.

also when i export vmdk file, am only am able to backup DC-1 file, the DC-2 file take lot more time to export so i have to cancel it.

So you added it only to the ESXi host and not to the VM?

[feroz201110141]

yes i think

Okay. so what you did is you added the disk as a "raw device mapping" it seems. Which means you won't see the disk file on the datastore as you would expect, but you are using the full 3.8TB device for the VM "raw". Which means that 3.8TB device doesn't have the VMFS filesystem, but is directly used by your guest operating system.

what should i do now?  if i delete the Hard disk 2 from guest setting it make any issue in my Domain contrl  lor my guest operating system will affect any thing ?  even i didn't  store anything in the disk 2.

You can just remove it from the VM in the VM settings, then remove it from the within the VM as well.

After that you format the disk with VMFS and then you can create a virtual disk with the size you need for that vm.
