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.
