Solaris 2.51 CDROM/sbus@1f,0 troubles

I am a new system administrator on a Solaris 2.51 box.   The box is on our network with a new name, IP address etc.  All the drives and devices appear to functional except for the CDROM.  
I can't mount, can't eject, can't unmount.
For example:
> mount -r -F hsfs /dev/dsk/c0t6d0s2 /cdrom
> mount point cannot be determined

Note:  Pressing the manual eject button on the cdrom drive doesn't do anything.  

More importantly, I am getting a startup error which is obviously the cause... but I don't know how to fix this:
Warning: /sbus@1f,0/SUNW,fas@e,8800000 (fas0) :
      Connected command timeout for Target 0.0

Any recommendations on how to proceed?
thanks in advance.
