I'm getting SCSI timeouts on my tape backup drive. The box is a Dell Poweredge 1300. (I know it's old). I swapped the drive but nothing changed. The SCSI controller in onboard. My Dell rep suggested a new controller card PCI and cable which I now have in my possesion (AHA-2940). The manual says to load aic7870.dsk or aic78u2.ham drivers in the startup.ncf. My concern is that there already is a line loading aic78u2.ham in the startup. I'm not sure how to proceed. Any suggestion would be appreciated.
