SCSI Configuration screen not updated when Mylex DAC960 is selected
Last modified: 2008-05-01 11:37:50 EDT
When a sytem is configured with a Mylex DAC960PTL, it is not found during the SCSI scan and the user is asked if there are are additional SCSI adapters. After selecting "yes" and then selecting Mylex DAC960 from the adapter list, the install script returns to the SCSI configuration screen, but does not list the DAC960 as an adapter found. From there the user can select "No" and installation will continue normally just as if it had in fact found the Mylex DAC960. The failure was recreated on several systems w/ the DAC960. If an AMI MegaRAID adapter is substituted for the Mylex DAC960, the SCSI Configuration is updated correctly when AMI MegaRAID is selected from the list of adapters.
The DAC960 driver does not use the SCSI midlayer in the kernel, therefore it does not show up in a listing of current SCSI adapters. The Compaq Smart/2 array controllers do this as well. The AMD MegaRAID, however, does use the SCSI midlayer. Until there is a common interface for RAID controllers that don't use the SCSI midlayer this will not be fixed - as the problem is really only cosmetic and not functional.
