If your disk did not come from Dell, you must use the Dell Disk Manager Setup to low-level format the hard disk before completing the following:
Set up one or more composite drives using the Dell DOS software array manager program.
Make one composite drive on controller 1 "Drive 0 - Composite Drive A."
This will be the drive containing the bootable Solaris partition.
Select any RAID level supported by the controller.
All disk drives used by the Solaris software (except the CD-ROM used during the initial installation) must be composite drives having one or more physical drives.
Enable Adaptec AHA-1540 emulation on the CD-ROM drive:
Save your configuration changes.
