Re: Cache Battery Swap ?

[DrFranken <midrange@xxxxxxxxxxxx>]

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.'
