I suspect it's a firmware issue. I've been through the setup screens
and didn't see anything that looked relevant. I can try to find if
Cisco could give me updated firmware for the server, but I'm not
confident.
I feel like there could be something basic I'm missing given the other
server can address 4TB. Maybe someone with IBM firmware experience
knows which direction I should look.

It's a hardware limit of this HBA controller.
Switching to SAS drives should give you 3TB instead of 2TB. You will
have to reflash controller with newer IT firmware from Broadcom, if it
is still available for download, and you will loose RAID functionality.
There is nothing you can do for SATA drives.
Without exaggeration, this controller is based on ARM966 chipset from 2004.
You can't expect full compatibility with modern devices from a hardware
that is 20+ years old.
