We have an iSeries 810 with 175 GB of system storage, 85% used. We IPL weekly. The IPL typically takes about 15-20 minutes. We perform an entire system save monthly, which takes about 5 hours in restricted condition. We have gone *at least* 3 years without running RCLSTG. Given that info, can anyone come up with an educated guess as to how long RCLSTG *ALL will take? Will it take a relatively short (compared to an entire system save) amount of time, like 3 hours, or a ridiculously long time, like 12 hours? We operate 24/7, but could afford 6-7 hours of downtime on a late Saturday night, but definitely not 12 hours. If it will take a loooong time, is there any way to break it down into smaller chunks? If it takes longer than we expected and we need to abort, is there a safe way to do so, and if we do, will we get any benefit from the portion that we ran thus far?
On a related note, are there any pitfalls or advice to using RCLSTG that we should be aware of?
