Have a new Proliant DL36 with an attached MSA70.

It's 25 disks times 146Gb witch makes it possible to create a little bit a
over 3Tb volume. But... To create volume that large i had to configure the
RAID in two logical volumes (~50/50). And after that i created partitions and
in the same manner (~50/50) and to get one lager 3Tb volume i had to span the
pool over the two partitions.

Isn't it possible to create just one large logical volume (in this case just
above 3Tb) and then create one partition, one pool and one volume?

Is there a limitation in NW partitions for volumes above 2Tb or something?

Or what could I possibly do wrong?
