new 2TB LUN for VMFS, VC only sees 97.99GB free space

[mfair]

I have a new CLARiiON CX3-40F that I am going to be migrating my VM's to. (very thankful for SVMotion, and the SVMotion VC add-in found here works quite nicely)

I have created several 1TB LUNS for vmfs, (full 4+1 raid groups on 300GB drives). These all show up in the Add Storage Wizard as they should, 1.05TB capacity, 1.05TB available.

I have also created 2 - 2TB LUNS for vmfs (full 8+1 raid groups on 300GB drives). These show up as 2.10TB capacity, 97.99GB available. What did I do wrong?

Hello,

2.10 TBs is greater than 2TBs. It has to be 2TBs or less, nothing greater.

Indeed - if its over 2TB, it will only show the space > than 2TB, or .1TB (aka 99.99 GB that you see).

ahhhhh I see it now. I read the specs too quickly. I saw the 64TB limit, didn't realize that it meant 2TB with bunch of extents.

Is the any harm in carving that 2.1TB raid group into 2 - 1+TB LUNS for VMFS or should I leave it as one volume and burn the 100GB?

Thanks for the help,

Mike
