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 na=EFve 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
