Evaluating the current configuration

Before you change the disk configuration of your system, it is important to know exactly where the existing disk units are located in relation to disk pools, IOAs, and frames.

The graphical view of IBM® Navigator for i eliminates the process of compiling all this information by providing a graphical representation of how your system is configured. You can use the graphical view to perform any function that is possible through the Disk Units list view of IBM Navigator for i, with the added benefit of being able to see a visual representation. If you right-click any object in the table, such as a specific disk unit, disk pool, parity set, or frame, you see the same options as in the main IBM Navigator for i table.

You can choose how to view the hardware in the Disk Unit Graphical View window. For example, you can select to view by disk pools, and then select a disk pool in the list to display only those frames that contain the disk units that make up the selected disk pool. You can select Show all frames to see whether or not they contain disk units in the selected disk pool. You can also select Show device positions to associate disk unit names with the device position where they are inserted.

You can right-click any highlighted blue disk unit in the graphical view and select an action to perform on the disk unit. For example, you can select to start or stop compression on a disk unit, include or exclude the disk unit in a parity set, or rename the disk unit. If the disk unit has mirrored protection, you can suspend or resume mirroring on the disk unit. If you right-click an empty disk unit slot, you can start the Install Disk Unit wizard.

To activate the graphical view from your IBM Navigator for i, follow these steps:

  1. Select Configuration and Service from your IBM Navigator for i.
  2. Select Disk Units or Disk Pools.
  3. From the Actions menu, select Graphical View.
