Kenneth, I can attest that the balancing can be run on a live system, we have it on our job scheduler to run it every Wednesday evening. (We run the trace during the busy hours of our working days, then tell it to do the arm utilization balance in that Wednesday run.) However, it's never actually had to do any balance adjustments, since we haven't added any disk since we went to V4R4 and there haven't been any radical changes in our usage patterns. We also run the STRDSKRGZ regularly, which is basically a free space defragmenter. It runs an hour or two each night on our machine (720 207A with 146 GB in 8 GB drives with RAID). There's probably no great benefit to running this, either, since we stay between 55 and 70% of capacity all the time, but "running a defrag tool" is a good security blanket for my management, which is only semi-AS/400 literate (long-time Burroughs shop, moved to NT and AS/400).

Spartanburg, SC -----Original Message----- From: Graap, Ken [mailto:keg@exchange.gasco.com] <much snippage> Has anyone added disk on V4R4 or V4R5 and used the new disk balancing processes? I understand that they can balance disk in the background while the system is open to users. +--- | This is the Midrange System Mailing List! | To submit a new message, send your mail to MIDRANGE-L@midrange.com. | To subscribe to this list send email to MIDRANGE-L-SUB@midrange.com. | To unsubscribe from this list send email to MIDRANGE-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +---
