In the above image, under Cache for the XP disk array 10055:
• Cache is the main category. The number (6) indicates the number of CLPRs partitions configured
on the selected XP disk array.
• The CLPR0 and CLPR1 are the individual CLPRs.
The related metrics associated with the Cache and CLPRs are displayed in the Choose Metrics box.
Select the metrics at the component type or the individual component levels, or both to view the related
performance graphs in the Chart Work Area. For a description of these metrics, see “Metric Category,
metrics, and descriptions” on page 441.
The following table provides the default set of metrics that are displayed in the Choose Metrics box.

NOTE:
For an XP10000 Disk Array, the MIX boards do not have MP4, 5, and 6 defined. So, when these
metrics are chosen, the utilization is shown as zero.
The Utilization metric is available for the DKAs that are associated with the concatenated RAID groups.
All the associated DKA pairs are displayed individually in the Resource list box on the Charts screen.
TIP:
For CHIPs that are not installed, the MP utilization shows zero.
