Jose,

The redbook is dated 14.12.2000 and I cannot recall when 6228 went out. It
either was brand new or was not available. Thus was not cited in the
redbook.
But you are absolutely correct - it applies to both 6227 and 6228 adapters
(in fact last installations I make are on 6228's :-).

Henry,

sorry for delayed answer (have been on a training and was unable to read
all
mail on time). As expected you did not changed the adapter (to handle
larger
blocks for tape operations). Look at max_xfer_size parameter - it has to
be
changed to 0x1000000 (one zero more, in decimal from 1 MB to 16 MB). This
is
NOT described in any of TSM's manuals :-(( It can be found as Important
note
on p.52 in redbook "Using TSM in SAN Environment" (SG24-6132-00), Chapter
3
"Building a SAN Environment", section "3.1.1. RS/6000".

No, I did not changed any settings for the FC HBA. The output of the AIX
command "lsattr -El fcsN" are the following:

intr_priority 3          Interrupt priority     False
bus_io_addr   0x2ec00    Bus I/O address        False
bus_mem_addr  0xc8020000 Bus memory address     False
lg_term_dma   0x200000   N/A                    True
max_xfer_size 0x100000   Maximum Transfer Size  True
num_cmd_elems 200        Maximum number of COMMANDS to queue to the
