Appendix B. Using the DS6000 with iSeries 349

Managing multipath volumes using iSeries Navigator

All units are initially created with a prefix of DD. As soon as the system detects that there is

more than one path to a specific logical unit, it will automatically assign a unique resource

name with a prefix of DMP for both the initial path and any additional paths.

When using the standard disk panels in iSeries Navigator, only a single (the initial) path is

shown. The following steps show how to see the additional paths.

To see the number of paths available for a logical unit, open iSeries Navigator and expand

Configuration and Service, Hardware, and Disk Units as shown in Figure B-30 and click

All Disk Units. The number of paths for each unit is shown in column Number of Connections

visible on the right of the panel

. In this example, there are 8 connections for each of the

multipath units.
