NOTE:
The chart may show the utilization as zero for invalid MPs. This is because the mix CHIPs
and mix ACPs have only four MPs each. For example, if you select Utilization Metrics,
from the metric category combo box in the Chart screen for an XP10000, and then select
utilization for MP 4, MP 5, MP 6, MP 7 for mix ACP Pairs, mix ACPs or mix CHIPs from
the Metric combo box, the resultant chart displays zero utilization for those MPs because
the MPs are invalid for mix PCBS.
Chart will not display the utilization metrics for concatenated ACP pairs.
TIP:
The individual CHIP utilization metric displays the average utilization of each MP in the
CHIP, the CHIP utilization per MP displays the utilization for each MP in the CHIP, and the
overall CHIP utilization chart displays the average utilization of each MP in the array.
Working with groups
You can also create and chart groups of specific host and array components by creating a group in
the PA XP Group Configuration screen on the Configuration tab. The Group Configuration screen is
a configurable Grid Display screen.
After you select the parameters for your group, the system returns the results of your selections. For
example, the system can add all the total IOs for invalid ACP Pairs, or it can add the LDEVs for a custom
RAID group. Ensure that you have selected every element that you want to appear in the chart, because
the system can chart only those elements that are specified. After you create a group in the Groups screen,
the new group automatically appears in the Array/Group drop-down menu in the Charts screen. Use the
Metric Category and Metric drop-down menus to select the metrics that you want to chart for your group.
