SUMMARY: Attaching sun cdrom on rs6k server?

My original posting was:

] I want to put all the SUN cdroms together on a IBM RS6000 model580 server
] but it seems that the ibm can't detect the presence of the sun cdroms though
] it has no problem identify its own (ibm) cdrom. I'm using the integrated
] scsi controller on the rs6k and I'm quite sure the connection is there as
] the green LED lighted up on the external scsi-bus terminator.
] The cdroms worked fine on a sparc10. Anyone with similar experience could
] you please enlighten me on how to get it works?

I received several responses all pointed to the same direction -- it cannot
be done. Someone mentioned that may be IBM uses 1024 bytes/sector instead
of the 512 bytes/sectors used by SUN. Another response pointed to a
similar summary which probably can be found using the WAIS server. The
reply I received from John Murtari contains a lot of details and information
which I will append below.
