I/O errors on 6TB device

[Bernd Schubert <bernd-schubert@gmx.de>]

Hi,

recently I asked about problems to expect with >2TB devices and the answer
of Douglas made me hope we won't get any problems this time.
Unfortunately, we get I/O errors on accessing the device.

The unit is called transtec PV610S, which is actually an Infortrend EonStor
A16U-G2421-1 device.

Presently its running in test mode on our failover system with attached to a
MPT scsi controller, after thouroughly tested it is supposed to become our
main storage device on our primary server with an AIC79XX controller.

Without any knowledge about the scsi protocol and its error numbers it looks
like the device is claiming to have more sectors than it actually has,
doesn't it?

Now using parted to set a proper partition table, parted will complain about
an I/O error and dmesg shows the messages below.

Any help is appriciated.

Thanks in advance,
