I recently had to install Solaris 10 on a old Ultra 10 workstation and had trouble figuring out which device was the cdrom…
This is how I found it;
# iostat -En
c0t0d0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0
Model: IC35L060AVER07-0 Revision: ER6OA46A Serial No: SZPTZNM
Size: 61.49GB <61492838400 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 0
c0t2d0 Soft Errors: 3 Hard Errors: 0 Transport Errors: 1
Vendor: SAMSUNG Product: CD-ROM SC-148F Revision: PS06 Serial No:
Size: 0.49GB <492834816 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 3 Predictive Failure Analysis: 0
I could then mount it;
mount -F hsfs -o ro /dev/dsk/c0t2d0s2 /mnt/cdrom
