Including disk units in a parity set

 

When you attach a new disk unit to an existing IOA that has device parity protection, you can include the disk unit in a parity set with other disk units.

If you want to include a disk unit in an independent disk pool that is unavailable, first IPL your system. For all other disk pools, you need to restart your system to dedicated service tools (DST) mode before including them in a parity set.

Adding three or more disk units requires you to create a new parity set. The include function does not work when creating a parity set. To create a parity set, go to Start device parity protection.

To include a disk unit in a parity set, follow these steps:

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. Select the disk units that you want to include.

4. Right-click a selected disk unit and select Include in Parity Set.

5. From the resulting dialog box, click Include to include the selected disk units in a parity set.
