HP XP Performance Advisor Software - Manual (Page 84)

The following are important notes on custom groups:
•
The LDEVs associated with multiple RAID groups or multiple ACPs are treated as separate
group of items. For example, if you have an LDEV associated with the RAID group 1-1 1-2,
you must select 1-1 1-2 in the RAID Groups list. An LDEV mapped to the RAID group 1-1 1-2
is treated separately from an LDEV mapped only to the RAID group 1-1 or 1-2.
•
If HP XP7 Performance Advisor is upgraded from v3.2 or earlier to the current version, the
existing custom group names are automatically appended with _CG.
•
Each page on the Custom Group screen displays 150 LDEV records. The selection of records
on the current page is retained when you navigate to other pages.
•
The custom groups uniquely identify the LDEVs based on the following LUN attributes:
Host groups ◦
◦ RAID groups
◦ Host IDs
◦ LUSE
If there is a configuration change in the above-mentioned LUN attributes, edit the custom
groups to add the corresponding LDEV records again. It ensures that you view the updated
data on the LDEVs and the associated LUN attributes.
•
If you group the LDEVs by host groups and then modify the name of the host group, delete
and re-create the custom groups.
Creating custom groups
To create a custom group:
1.
Click Customize Settings+Custom Groups in the left pane.
The Custom Groups screen appears providing the list of LDEVs and their associated components
in the Custom Groups table (see the following image).
2. Select the LDEV records for which you want to create a custom group. While selecting the
records, use the Shift or the Ctrl key for selecting multiple component records.
3. Enter a name in the Custom Group Name box. You can enter a maximum of 24 alphanumeric
characters that includes underscore (_). Special characters, such as the hyphen (-) and comma
(,) are not allowed.
4. Click Create Custom Group. The Create Custom Group button is enabled only when you select
LDEV records in the Custom Groups table.
The selected set of LDEV records are included in the custom group and the new custom group
is listed under List of Custom Groups. You can view the custom group details by clicking View.
