SCSI pass-thru driver for AIX/RS6000?

[Serge Issakov]

Does anyone have any experience with a SCSI pass-thru driver for
AIX on the RS6000?

More specifically, has anyone used the standard 'scdisk' driver in
Diagnostic Mode and passed SCSI commands to it using the sc_iocmd
struct from /usr/include/sys/scsi.h?

I would appreciate any information on this subject.
