- I recently had this happen on my IPC 4/40. It was due to a trashed
- out boot block -- acquired for reasons unknown. The machine had
- been sitting idle over night, but when I came back in the morning,
- "taget esp0 now synchronous at 4.167...," messages were spewing out
- on the console window. When I left for the evening, only calendar
- manager and a shell tool were left running; nothing fancy going on.
-
- The machine was too hammered, so I tried L1-A and sync. When I did
- a boot sd, I got the "illegal instruction" message.
-
- I had to boot off cdrom, but on a sun 3, you'd probably boot an O/S
- tape from st(). After the cdrom/tape boots, pick "install mini
- root". After you've got a mini root (presuming the hard disk isn't
- totally hammered), you can probably manually fsck the partitions on
- the hard disk. If the fsck barfs, try running format, picking the
- repair option on any bad blocks reported by fsck. When finished
- with format, try fsck again.
-
- The mini root option on the O/S tape installs a stripped down
- kernel and essential tools in the swap partition of the drive
- without blowing out the /usr and /home partitions on the hard disk.
- The mini kernel is configured to not swap.
-
- Knock on wood, my IPC has been running fine now for about a week
- since I had to do the repair operation outlined above. The machine
- is only a few months old, so it made me a bit leery to have the HDU
- develop a grown defect [in an important area] so early in its life!
