To extend the VMFS volume:

Select the host on which the virtual machine resides and click the Configuration tab.
Select the datastore on which the virtual machine resides and click Properties.

Note: If there is no available storage, a new LUN must be presented to every ESX host that can see the LUN.

In the dialog that appears, click Add Extent and follow the prompts in the Add Extend wizard to add an extent.
Perform a rescan on every ESX host that is being presented the new LUN so that the addition of the extent is detected.

Create a New LUN on the SAN and present this new LUN to the ESX host server. This will be the new LUN, that the existing datastore is expanded into.

so Existing LUN A + Newly Created LUN B = existing datastore but expanded.

Select the properties of the existing datastore, and select INCREASE

Select the new LUN to Extend/Expand the datastore into, and follow the wizard, select Next three times, and select Finish.

Refresh and Re-Scan Storage Controllers, and the datastore will have increased in size.

I have a LUN with free space on the list of datastores on my host but it doesn't show up when I click increase. matter of fact, I have a few in the list with several hundred GBs of free space but they don't show up when I click increase either. what am I missing?

thx

If you made an update on the host from 3.5 to 4 than it is not possible to increase the current volume.

Make sure you have not already added and formatted it as a datastore

Yes, you just need a blank LUN.

glad you are extended, make sure you update documentation, to state this datastore is now extended and using two LUNs.

if a single LUN fails the datastore will fail.
