ciss(4) not coping with large arrays?

[Emil Mikulic]

Hi all,

Running today's RELENG_7 (although 7.0-RELEASE has the same problem),
GENERIC kernel on an amd64 and I can't seem to get a da(4) device for
any arrays bigger than 2TB.

dmesg:
<...>

The arrays I'm testing with:
da1 = 1 x 1TB
da2 = 2 x 1TB
da3 = 3 x 1TB
da4 = 4 x 1TB

Also:
# camcontrol devlist

<COMPAQ RAID 0  VOLUME OK>         at scbus0 target 1 lun 0 (pass1,da1)

Is it possible to get FreeBSD to recognize arrays > 2TB?
Are there any further diagnostics I can provide?
