3. In the Physical LDEV text box, enter the cu:ldev format of the LDEV that you want to search and
click the Search icon.
The component selection tree for the XP or the P9000 disk array that has the matching LDEV
component automatically expands to display the LDEV highlighted for your reference. (If the
component list for the selected XP or the P9000 disk array is large, you may have to use the
scroll bar to navigate through the list of components to view the matching component).
In the above image, the physical LDEV 1:00 belongs to the RAID Group 1–10 for 53036 (P9500
Disk Array).
Managing alarms history
P9000 Performance Advisor maintains the history of alarms for components, if the alarms are already
configured and enabled on them. The history of alarms is displayed for the following time stamps in
the Alarms History table:
1. Time Posted: The time when the performance of a component went beyond or below the threshold
level, and a new record was posted. When a new record is added for a component the first
time, the Time Posted time stamp will be the time when an alarm was configured on the component.
2. Time Updated: The last time when the component was monitored for change in performance
value (if the performance of a component exceeded or dropped below the set threshold level).
3. Time Dispatched: The time when the alarm notifications were dispatched. The current performance
value of a component is also displayed.
Initially, the message No records found matching the given filter criteria is
displayed if there are no component records posted in the Alarm History table.
To view the Alarms History table, click Monitoring > Alarm History in the left pane (see Figure
9 on page 151).

Understanding alarms history
For P9000 Performance Advisor to start monitoring the performance of a component and generate
an alarm, you must configure the required threshold and dispatch settings on the Activate Alarms
screen, and also enable an alarm for that component. For more information on configuring alarms,
see “
Configuring notification and monitoring settings ” on page 140. After an alarm is configured,
P9000 Performance Advisor monitors the performance of a component from the next data collection
cycle. A new record is displayed on the Alarm History screen with the time of posting appearing
under Time Posted.
IMPORTANT:
P9000 Performance Advisor posts the record only if data collection is in progress for the XP or the
P9000 disk array to which the component belongs.
