HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

• View a graphical representation of the associated LDEVs performance for specific LDEV metric
and duration of your choice. For more information, see “Plotting charts” on page 264
• Configure alarms on the associated LDEVs, so that P9000 Performance Advisor monitors and
sends appropriate notifications to intended recipients. For more information, see “Setting threshold
and dispatch levels” on page 149
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 P9000 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.
Creating custom groups
To create a custom group:
1. Click Settings in the left pane.
2. Select Custom Groups.
The Custom Groups screen appears providing the list of LDEVs and their associated components
in the Custom Groups table (see the following image).
3. 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.
4. 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.
