I would think this type of solution could be used for MPE, just by
installing an alternative boot disk with a simple system volume after
changing the boot path, although stage/ix is more elegant. This type of
boot disk swap fix kind of thing is done all the time in the traditional
Unix world. I also recall switching boot disk packs on a PDP/11 (after
confirming the problem wasn't a head crash!) - easiest way I've ever
seen to fix a system boot problem with the file system (floppy disk boot
included).
But, perhaps we don't hear about this solution for MPE because it is
rarely needed and a CLST or SYSDUMP tape works well as a fix when it is
needed? When was the last time someone had an MPE box that would
couldn't start MPE due to file corruption or missing system files (i.e.,
not hardware failure)?
Interesting that there were so many stories about fixing this type of
problem with NT.:-) I don't think MPE was like this when it was in it's
4th major release (would that be MPE IV?)? (yes, NT is more complex,
etc., etc., but my problem is Microsoft didn't design it to be able to
recover in these cases when they knew the goal was a robust server
system).
