You most likely have a Snap Shot on the VM if you remove the Snap Shot you should be able to increase the drive size.

either you have a snapshot or your disk is IDE!

IDE disks do not support increase, and you will need to change to SCSI, the easiest method is to use VMware vCenter Converter Standalone 5.0 to create a V2V, and at the same time also grow the disk.

see my EE Articles

check if you have a snapshot

do you have a snapshot?

if you have disk0 and disk1, these are disks, not partitions, two partitions would appear on a single disk.

can you screen shot disk management settings, and also VM Settings , Right Click VM, Edit Settings - Screenshot - upload here

Thank you all for your quick reply.
I figured out that another storage NeApp was connected to this VM's windows 2008.
this is the reason it did not show up in esxi !!
