Changing parity set optimization for RAID 5 protection

 

If you use an V5R2 IOA and OS/400^® V5R2 or later, you can choose how you want your parity sets to be optimized. To change the parity set optimization for all new parity sets that are created, use the following steps. This change stays in effect until you change it again. If you need to start parity, you can also change the parity set optimization as part of the start parity process.

1. In iSeries™ Navigator, expand My Connections (or your active environment).

2. Expand the System i™ you want to examine,Configuration and Service > Hardware > Disk Units.

3. Right-click Parity Sets and select Change Optimization.

RAID 6 protection gives you optimal performance, capacity, and balance. So selecting any of the parity set optimizations does not affect the outcome of the parity set.
