Try to see if you can fix the disk with fsck.
Insert solaris cd.

>boot -s cdrom
>fsck /dev/rdsk/c0t0d0s0

If this goes OK then you probably  just can reboot the system.

With no error message it's hard to tell if it is a hardware problem.
If the disk is damaged then change disk and use backup to restore the system/reinstall.
Maybe you have to use the backup/reinstall to restore the system even if the disk isn't damaged.

I tend to agree with Emil.....
Solaris isn't forgiving, when it comes to harddisk.. They have to be right.
Your harddisk may have more errors  than Solaris can tolerate.  If this
is so, you can low level format it in a Win/Intel PC and then reinstall on the
solaris system.  (I'm assuming your HD is a SCSI)  This might fix the drive enough
to be usable.  I would first try the disk in another sun system and perhaps in another
type of unix based computer.  Verify 1st that the Harddrive is the problem.

There are two other areas that could cause you problems as well.
 1. Your SCSI cabling could have gone bad.
 2. Your Harddrive controller could be bad.

If you have known good parts and known good systems you can swap out parts to
determine which part is bad.
