I've just installed three 2 TB SAS HDD's on our HP SAN as RAID 05 Virtual Disc. So the available disc space for usage is 4 TB.
I can see the new LUN on VMware ESXi, 4.1.0 on Configuration Tab, Datastores>Devices as LUN 4 with Capacity 3.64 TB ( Fig1).
However when I added this new LUN to existing Datastore ( Name:300gb) on ESXi, the capacity of this LUN is 1.64 TB instead of 3.64 TB. What could be the problem here please ? And how can I get full 3.64 TB space for usage
