HP 2012fc SAN Available Volume Capacity Wrong on ESX 3.5 -- help

We have VM ESX 3.5 installed on a a new HP Proliant DL380 G5. ESX works great on the server with local and NFS attached storage.

The issue we are having is with the new SAN. This is a HP Storagework MSA 2012fc.

This is connected via fiber channel as a direct connection over fiber. The connect is working, ESX finds the volumes on the SAN.

The issue is with size and capacity. I have a RAID-5 vdisk 5.5 TB usable, with 5.5 TB volume. The ESX server recognizes a 5.0 TB capacity with only 1.x TB usable.

I then removed the the 5.5 TB volume and created 3 TB and 2 TB volumes to test. ESX would only see 745GB available in 3 TB!!!!

And 1.82 TB Available on the 2 TB.

Is there a maximum size limit for FC - LUN's? Should I manually partition from the ESX command line?

I looked at the HP MSA 1000/1500 Connection profile hack, but this CLI doesn't do connections the same way.

Welcome to the forums - the maximum LUN size the ESX and ESXi can access is 2 TB - so you will have to create 2x2 TB and 1 TB LUN - and regards to the lost space on the 2 TB LUN some space is take to maintain header information about the VMFS datastore

Thanks for the help. I knew there was something I was missing.:D

Performance on ESX vs Vmware Server is great so far.
