Drivers not get detected while installing Solaris on Hp server

I m having server with a mode; HP Proliant DL380 G5.

Having 8 disks 148Gb each, as i m going for solaris 10 installtion it gives error Disk not found.

Its not detecting Drivers.

Kindly tell me how to for the driver detection.

You have setup the hard disc from the BIOS? You press something like the F10 key during boot up to go into the BIOS to configure mirroring, RAID etc., perhaps this needs doing first?

This has a lot about a similar problem here:
