Unable to see drive greater than 2TB under FreeBSD 5.3

[henry]

I have recently been asked to attach a ~5TB external raid array to a FreeBSD
machine.  On attaching it, FreeBSD claims it is only ~1TB in size.

I have tried (in no particular order): rebooting, changing the SCSI card
geometry munging option (does this do anything??), creating a partition
using fdisk and gpt which covered the entirety of the disk, all to no avail.

To my naïve eyes it seems the mpt driver is not aware of "extended
translation" however I cannot see where to fix this in the driver, or have
any confidence in this guess!

Can someone tell me where to look next?

Thanks

Henry
