Walter,

first, I would recommend you to use newer version of the Atape drivers -  we
have tested
the 5.3.9 level with 3570s through Data Gateway.
Then try to issue hostTypeShow on the Data Gateway and make sure that the
port to wich is the AIX
box connected is of type AIX. The default parameter is NT. You can change
the host type with the
setHost command on the Data Gateway.
On AIX, issue lsattr -El fcsX (where X is the number of the fcs device) and
check the max_xfer_size parameter, which is by default of this value
0x100000, but you need to change it to 0x1000000.
If it won't work after all this, try to issue initializeBox on the Data
Gateway, then remove all the tape devices on AIX and reboot (not only
cfgmgr).

And of course, first of all, I would recommend you also to try to connect
the drives locally through SCSI to your AIX box - only to make sure that the
problem is not in the drives itself.

Leos
