Re: Load Source Replacement

Having done a SAVE 21 as a 'Just in Case' is reasonable, but consider:

Jerry mentioned the cache battery was dead. This combined with a missing drive means this save is going to take a l-o-n-g time and seriously stress the remaining disk units during that time. This means you'd be operating that much longer with a dead drive and if another, aging unit, fails you're toast. Being the LS is the dead guy you really do have to restore at that point. If the save hadn't completed before the second disk failure then all you have is, well, nuthin.

I have done so very many disk unit replacements that I would have done what Jim said initially: Concurrent maintenance out the dead guy, install the replacement, start the rebuild. On 35GB drives that's maybe a 45 minute rebuild (likely more with aforementioned dead cache battery.) That is the expected path for a disk failure, get it repaired as soon as possible to prevent a second failure from being fatal. [This is the entire reason for hot spare!]

Jerry, do you keep software/hardware maintenance on this machine. When was
the last 21 save done on it?? I guess I am under the impression that he
wanted to do a 21 to save himself in case he ran into any issues and then
would be forced to reload the machine. What would of happened if he did
hit a bump in the road, what would have been expected of him at that point.

Well, the BP'll have to eat that bill. The reason my boss and I still have
access is to check on the machine and run any reports are whatever that the
owner needs for taxes and such. When I finally logged in myself at the end
of February, I noticed the drive went south back in November! It's a
simple
matter of checking the qsysmsg queue, which I had set up years ago. Plus I
told 'em, before they picked the machine up, that it needed a new cache
battery (well, the amber light was on, anyway) and that they ought to turn
off the light.

No, I don't know what the owner is paying these guys, but I'm definitely
going to let him know that he shouldn't pay any bill for the repair.

Thanks for the verification, Jim. Once I found out who was doing the work,
frankly, I didn't have a whole lot of confidence; he used to write programs
here as a consultant before I came on full-time. How much faith can you
have in an IBM i programmer who writes new code in RPG II?
