Hi Experts,
I have running vSphere 4.1 on ESXi 4.1.
When I want to increase my datastore, there is no LUN to click or increase.
How to do this ?

Well, you can create an 'extent', if you have contiguous space on your LUN/datastore volume. But creating extents isn't really recommended by VMware. They recommend you recreating your datastore to the size you want (with appropriate block size), or adding another datatstore with the size you want. What is your current storage setup? Do you have local storage or SAN?

You need to present a new LUN to the ESX server.

Then select the properties of the datastore, and select increase, pick the new LUN, and it will increase the size.

I have a SAN from DELL, EqualLogig PS4000.
When I create a new LUN and increase the datastore, is this then an extent ?
I just want a bigger datastore but not a datastore which is out of extents.

Yes; well, an extent is just 1 'addition' to your datastore. So, it wil be all that it is. But, if you need to continue to increase the size of your datastore, you can add up to 32 extents (2TB each, for a total of 64TB datastore storage). See KB:
http://kb.vmware.com/kb/1752
and Config Guide (pg. 118): http://www.vmware.com/pdf/vsphere4/r41/vsp_41_esx_server_config.pdf

It depends on how your SAN works, with some SANs, you can increase the size of the current LUN, re-scan on ESXi/ESX, and then increase the datastore size in the current LUN.

otherwise, you would have to add a new LUN to the existing datastore, so one datastore contains two LUNs (and is made up off extents).

Can you increase the size of the current LUN on the SAN?

Keep in mind, one caveat to using extents is that if you lose access to one of the LUN "extents" in your datastore, it will cause serious issues with the entire datastore.  This is the main reason why I recommend against using extents.

ok, I have seen, I can modify my LUN's.
So hopefully I can change my datastores.
