Re: Balancing disk drives

What has not impressed you? That the process took a little over 8 hours to complete, or you do not see much in the way of a change? I don't know what time period the WRKDSKSTS observation is for, if it's not about 5 minutes or so, it's not representative of what's going on anyway.

Maybe the system was already well balanced from a usage standpoint. Granted it could not have scattered it across a disk that was just added, but over time it would have.

Then I ran TRCASPBAL. When that was done I fired off a STRASPBAL, this time with TYPE(*USAGE) instead of *CAPACITY (used by Add units and balance data). Apparently it's moving a lot around from that one busy disk. The rebalance is still running...
