SCSI OP 2ah with too big sectors 2056 exceeds backend hw_max_sectors: 2048

Hello,

We're having a setup running with Ubuntu 13.04 and 13.10 for target and
VMware 5.1/5.5 as the client. In this setup we're using 4 Gbit FC using
QLA2460 adapters. Everything works quite well except we keep on getting
kernel warnings like:

[1401151.960377] SCSI OP 2ah with too big sectors 2056 exceeds backend
hw_max_sectors: 2048

This happens every few seconds and is consistent across several systems.

Our setup is Raid 10 and 5 using mdadm using FILEIO in buffered mode. We
chose this since it gives really great performance and uses memory for
caching.

However from what I read then this value 2048 is hardcoded into the kernel
and there is no way of changing this.
Am I right on this?

Any way to get this fixed or some workarounds for this?

Thank you.
