URGENT: Windows does not recognise MSA2000 volume

I had a ML370-G3 Windows 2003 Server with an Emulex fiber channel card connected to a MSA200 StorageWorks that holds a 5 TB volume.

I moved the card to a brand new ML370-G5 and after installing drivers, etc., Windows's Disk Management shows the disk as "Unallocated space"!
I have another volume (a 500Gb volume) in the same MSA2000 that it's recognized perfectly.

Any ideas?
Thanks a lot!

I start most of the Windows troubleshooting with a reboot of the server...
If that does not solve the problem, check the multipathing software driver etc

If that does not solve the issue, I would definitely contact support so that the logs from MSA can be analyzed as the server part has been verified.

Thanks!

I restarted several times, updated drivers, etc., and it does not resolve the problem.

Jorge,

Can you give me the LUN details?

I know that 500GB LUN can be seen OK.

Whats the size of the other LUN?

Was there something you had to do on the old server to recognize the 5TB size?

I have 3 LUNs:

A 207000c0ffd79ada 0 StorageWork 0 StorageWork_V1 5250.00 GB Default Enabled

B 207800c0ffd79ada None Disco de cluster 0 Quorum 5.12 GB Default Enabled

B 207800c0ffd79ada None Disco de cluster 1 Shared data 745.02 GB Default Enabled

The first one, that already has data, it's shown as Unallocated space.

Do you have SP1 installed on the new server?

Anything else that is different in windows between the old and new server?

Jorge,
Did you just say:

A 207000c0ffd79ada 0 StorageWork 0 StorageWork_V1 5250.00 GB Default Enabled ???

That's a 5.12TB volume! Are you using GPT file system?

because,the maximum partition size in NTFS is 2TB. NTFS actually has an upper limit of 16 Exabyte, but since current industry standard limits the Partition Tables to 2 to the 32nd power sectors (with 512B sectors, that's 2 TB), the actual current upper limit is 2 TB.
