Preconfiguration Information

Although the Dell SCSI Array (DSA) controller is physically connected to SCSI devices, the interface to composite drives (logical disks the controller has constructed out of one or more physical disks) is that of a direct access disk (DADK). SCSI commands cannot be sent to composite drives on a SCSI array controller. Noncomposite devices (such as a tape or CD-ROM) cannot be accessed with the dsa driver.

• Install the controller in any slot between 1 and 8.

• Do not use targets 0 or 7 for any SCSI device.

• Install your CD-ROM as target 6 on channel 0 of the DSA controller.

• If there are two DSA controllers, the CD-ROM must be attached to the one in the lower-numbered EISA slot.

• The disk drive(s) that will make up your bootable composite drive must be on channel 0 of the DSA controller.

• If there are two DSA controllers, the disk(s) must be attached to the one in the lower-numbered EISA slot.

• Up to 14 physical devices may be attached to a single DSA controller since each controller has two SCSI buses.

Known Problems and Limitations

• Creating more than six composite drives causes the installation program to fail.

• The Disk Prep window overlaps the Continue Installation selection and other items on the screen when installing with six composite drives.
