I hope disk and fs is fine, system don't show any error with disk or fs
I try boot with -a args and i think error not in chose slice.

Rebooting with comman: -a 
Boot device: /sbus/esp at 0,800000/sd at 3,0 File and args: -a
Root file system type (4.2 nfs)
Default root device: /sbus/esp at 0,800000/sd at 3,0
Root (block) device ('*' for list): /sbus/esp at 0,800000/sd at 3,0:
Partition ('a' - 'h'): 
Root on /sbus/esp at 0,800000/sd at 3,0 FSType 4.2
Boot:
Boot: vmunix
Boot: Lookuppn failed: Not a directory (errno 20)
Illegal instruction


How I can check FS? Or disk? 
Try on boot prom command diag any of args i see only:

diag ?
ok
