We've been mirroring for DR for many years. In the beginning, with late 90s technology, we could not mirror spool. Now with FICON over DWDM we mirror spool routinely. I can't remember getting any error on JES2 restart after recovery, which includes flashcopy of the secondary (XRC target) copy to a tertiary copy that we IPL from.

I made the rash assumption that Flashcopy (space efficient) with consistency group across the spool and checkpoint volumes would work, but it does not - get checkpoint errors and have to do a format and cold start. Read in JES2 manual that back up is not supported, however, not sure this was written before or after flash copy was invented. Seems to me that at any instant in time the data should be consistent? Also, disk mirroring should have the same problem but I doubt it does. Thoughts?
