I called the Dell customer service folks and they emailed me the link to the correct driver and it worked!
Driver: MegaRAID SAS 8888ELP
OS: Solaris 10 8-07 x86 version
Platform: Dell Power Edge 2950 (6 x SAS 146 GB 10K drives)
Link to driver:
http://www.lsi.com/storage_home/prod...te=1&locale=EN
I downloaded the file HWR_SAS_Driver_SOLARIS_1.17.zip and unzipped it using WinRAR to get a file called components.tgz. Unzipped that file and got the file mega_sas.iso. I then used Nero to burn the image to disk.
Booted from the Solaris 10 DVD again and when I got to options 1-6: I chose option 5, update drivers. Chose c for cdrom/dvdrom, inserted the dvd and hit enter. After I hit enter I got the message:
CD in /dev/dsk/c2t0d0p0 does not contain driver updates
extracting software in /dev/dsk/c3t0d0p0
installing driver update in the miniroot
Insert media and enter media type:
Floppy [f], CD/DVD [c] or End [e]
At that point I entered e for end and then put back in the Solaris DVD and hit enter. It went back to the Solaris config screen after that and then followed the steps as usual. I didn't get that error from before: No Hard Disks found.
