Changing the CACHE Battery on iSeries 170 Published by: Bob Cozzi on 20 Dec 2011 view comments(3)

Tonight I'm changing the CACHE battery on an IBM iSeries model 170.

Step 1: Cause an Error on the Cache batter using SST.

Step 2: Backup the entire system.

Good news/bad news:

The people that setup the backup actually think doing a save to save files is backing up.

The bad news is, I now have to do a full save to tape and since everything is also in a save file, I effectively have double the time a normal savlib *NONSYS would take.

Hi Bob,

There's a parameter on the SAVLIB command that will let you skip saving the contents of save files (SAVFDTA(*NO)).  I'm pretty sure it will work with a SAVLIB *NONSYS.

Sorry I didn't see this until today, but maybe it'll help for next time.

Hmm... SAVFDTA(*NO) would be OK only if all save files are "backups". If all of the "backups" save files are in the same library, you could OMITLIB() that library. If they're in different libraries, you could omit individual objects, which is feasible but obviously a lot more work.

You might need a combination of techniques. If "backups" save files are all in one library, but with other objects, omit that (entire) library from SAVLIB *NONSYS, then save that library individually with SAVFDTA(*NO), so that the other objects get saved. Just need to document that there's a separate library save after the *NONSYS in case you need the tape for recovery.

Right, we had to save everything including the contents of the savf's.

Sadly, they don't backup much of their system because the previous IT consultant thought save files were good enough--of course their system burned up in a fire in June so they lost the system, and therefore virtually everything else.
