Managing custom groups
XP Performance Advisor enables you to create custom groups of LDEVs that you want to monitor
frequently. The LDEVs can belong to the same or different XP arrays. After configuration collection is
complete for an XP array, the LDEVs belonging to that XP array and their associated details are
displayed on the Custom Groups screen. It appears when you click Settings in the left pane and select
Custom Groups from the list displayed. You can scroll through the list of records on the Custom Groups
screen to select LDEV records, and add them to a custom group.
You can also filter the existing list of LDEV records based on the associated ACP pairs, ports, and
RAID groups. This selection can be in combination with XP arrays or hosts, or both to view only those
LDEV records that match your specific requirement. After you create a custom group, you can:
• View the performance summary of the associated LDEVs. For more information, see “Viewing
