I have a Company 1850r with two 9.1 scsi drives. I am trying a fresh install of Redhat 9. When I get to the Diskdruid and try to manually install my partitions, only one of the drives shows up. sda...there should also be an sdb. Any ideas?

First check that each scsi drive has a seperate ID. There is probably a SCSI configuration ROM that will show you that during the boot process.

Secondly are the 2 drives configured by the controller board to be in some form of RAID array, in which case, you would only see one drive if the 2 drives were configured to image each other. Exactly the same - check in the SCSI controller ROM that you get during boot.

Hi :-)

I would try to run the installation with only one drive, and if it works, then run it again with the other drive, just to make sure that both of the drives work.

Once they work, check the SCSI ID and see that they are listed correctly when the computer starts up.

If those drives are connected to different SCSI adapters, try connecting both to the same and see if they are identified.

Hope it helps...
