Installation guide

Dell SCSI Array Controller
Solaris Device Driver:
dsa
Device Type:
SCSI Disk Array
Bus Type:
EISA
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.
Configuration Procedure
Using the EISA configuration utility:
