Re: load source concurrent maintenance

hi Joe

I THINK Larry meant that if your load source goes, replace it and get into DST to recover stuff - you have not done an IPL yet when in DST, as I recall. But I've not had to do this - crossing fingers - and I'm just trying to understand it, too. Seems the original poster had it go and did this very thing.
