• LDEVs is another main component type under PA_HPUX host group. The number 7 beside LDEVs

displays the number of LDEVs assigned to communicate with PA_HPUX.

• 3:88 is one of the LDEVs associated with PA_HPUX. The number 84 indicates the average I/Os

for LDEV 3:88.

For ports that are configured to communicate with the selected host groups, you can also view the

associated MPs and CHAs for the XP disk arrays, and only the CHAs for the P9000 disk arrays under

the Front-end category. For the LDEVs that are associated with the selected host groups, view their

RAID groups under the Back-end category. For more information, see “Front-end navigation

path” on page 269 and “Back-end navigation path” on page 275.

The related metrics associated with the resources types and components in the Host Groups category

are displayed in the Choose Metrics box. Select the metrics at the component type or the individual

component levels, or both and view the related performance graphs in the Chart Work Area. For a

description of these metrics, see “Metric Category, metrics, and descriptions” on page 435.

The following table provides the default set of metrics that are displayed in the Choose Metrics box.
