You will have to go to disk management and perform a rescan.

[abhilashhb]

To do this, right click on my computer and select manage. It will take you to device manager. Then at the bottom you will see disk management. Right click on it and select rescan. After doing this the disk will ask for initialization. Once you initialize it you can either use it to extend or crate a new partition. In your case rescan is enough.

Note: Always have a small question line and then explain your issue in the body of the discussion. Keep the heading short.

hi thanks for the response I already tried that I did not see the new space that I gave the vm after the re-scan. any other ideas what the new disk space not showing? the v/m is a win svr 08 enterprise

This is what the KB says

VMware KB: Increasing the size of a disk partition

Windows Server 2008, Windows Server 2008 R2, Windows Vista, Windows 7, Windows 8 and Windows Server 2012 can expand the volumes from the Disk Management in Computer Management. Right-click on volume and click Extend Volume. For more information, see Microsoft's documentation. Instead of rebooting the guest OS, you can right click on Disk Management in Computer Management and click Rescan Disks.

You should have seen it. Are you sure you are checking the right machine? Is reboot an option?

I found out what it is, initially it took the change to increase the size of the hard drive in the settings on the vm but when I went back to check it it went back to 256gb. I checked the data store its out of space I think more space needs to be allotted in the sans.

Yes that is the issue. You can ask the storage team to extend the LUN/add a new one so you can increase the datastore space. Then you can extend the disk as mentioned above.

With ESXi 4, the datastores use the VMFS3 file system which has a limited maximum file size that depends on the block size you used formatting the datastore (see VMware KB: Block size limitations of a VMFS datastore ). With the default block size of 1MB the maximum file size is 256GB. In order to create larger files (i.e. virtual disks) you either have to migrate the VM to a datastore with a larger block size or to re-format the current datastore, which would require to backup and restore all data on the datastore.
