Be aware that what you do prior to failing the battery matters! If you were doing a large amount of updating the cache might be quite full of data that needs to be written to disk. On today's large cache controllers it's possible for it to take 15 minutes OR MORE to flush out the cache to the drives. This is what is happening when you fail the battery (and also when you do PWRDWNSYS as well.) Until it SHOWS FAILED it's not done flushing, pulling the battery at that point would be 'a bad thing'. So Charle's advice here is spot on and now you know 'the rest of the story.'

Quadruple check that the current battery is flagged as FAILED prior to

You can force the flag in SST (DST?). If you don't check/fail it
yourself, watch as the CE does so.

More info in the archives....

Other than having the machine in restricted mode and the IBM CE access to
SST can anyone think of any other items that might need to be addressed
prior, thanks.
