Hi;

I have some problem regarding installing Redhat
ES(3.0) on prolient server DL380 it is not detecting
scsi controller. In that case can i install Linux on
IDE and then upgrade the kernel(which will detect the
scsi) and then copy the data from IDE to SCSI?

Will the procedure of copy (script descibed below)
work for IDE to SCSI ? or any additional steps
needed?

I am really sorry for posting this here but i am a
Debian user ..only due to customer insistence i have
to install RHL and i know i will get more sensible
answers to my technical questions here than on
Redhat.

Thanks and Regards;
Rituraj
