Re: Disk Balancing with V4R3

[Pete Massiello <pmassiello@xxxxxxxxxxxxxxxx>]

The command is used to rebalance disks in an ASP. It is on V4R3, but can be PTFd
to V4R2 (Mr. Neal "PTF" Clark can probably tell us the number).  This is a great
command to use after you add new DASD to an existing ASP.  Think about what
happens currently, you have 50GB of DASD at 80%, you then add 10GB more DASD to
that existing ASP.  Now you have the existing Disk units at 80% and the new 
disks
almost empty.  What the AS/400 does is concentrates all the writes to the new
disks, until they are even with the old disks as far as amount of disk space
used.  This new command should be used after installing new disks, to move the
data on the exisitng disks across all the disks in the ASP.  So in our example,
instead of the old disks at 80% and the new ones at 0%, after you run DSKBAL you
will have all the disks at 66% (roughly).
