ESX 3.5 Large Lun

Hey guys I have an odd problem. Typically with my VM's my LUN's are 800gb or smaller. However I need to make a large File server of about 3tb. So I wanted to make a small OS and then a couple large VMDK files. So I created a large LUN on the SAN, presented it to the ESX farm and it see's the capacity as 3TB however it says Available 1.03tb

I've attached an image of what I see. Anyone shed any light on this ?

2TB is the max LUN size for ESX 3 and vSpehre 4

You only have a 2TB limit in ESX...even if when you add the disk/LUN you add it with 8MB block size (see Configuration Maximum Guide for more info: http://www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_config_max.pdf). What you have to do is 1. create an extent, or 2. add 2 datastores/LUNs (1.5TB ea.).

Hope that helps.

2 TB is the Maximum LUN supported.  Also you should format the VMFS datastore with 8 MB block size oto allow a 2TB file( VMDK) size. However you can add other LUNs as an extent by clicking on "Increase size" from the properties of the  VMFS datastore. This will allow you to increase the size of your datastore up to 64 TB (maximum 31 extents).  (Note that even then single file size can not be more that 2 TB (means your virtual disk size can not be bigger than 2 TB)
