HP StorageWorks P9000 Performance Advisor Software v5.4 User Guide (T1789-96328, April 2012)

IMPORTANT:
The following are a few important points:
• After importing performance data for an XP or a P9000 disk array, ensure that you perform a
fresh configuration data collection for that XP or the P9000 disk array on the target management
station, as the archival process only exports the performance data. For example, if you import
performance data for an XP or a P9000 disk array that is not currently monitored by P9000 Per-
formance Advisor on the target management station, you cannot view its performance data until
a configuration collection is performed for that XP or P9000 disk array.
Also, if data is imported for the XP10000, XP12000, XP20000, or the XP24000 Disk Array, HP
recommends that you use the outband mode to collect the configuration data. This is because, the
internal raw disk capacity of the XP disk array received through the outband mode is accurate
(same as displayed by Remote Web Console) when compared to the value received through the
inband mode. So, if the SVP on a non P9500 disk array is accessible, outband must be the pre-
ferred mode of configuration data collection. It ensures that P9000 Performance Advisor collects
the correct internal raw disk capacity from the XP disk array. The internal raw disk capacity of
the XP disk array is displayed under Array Capacity (TB) on the License screen.
• If you initiate data import onto a target management station for overlapping date range and data
already exists in the management station's database, you are prompted to either archive or purge
the existing data and initiate the import process again. Consider the following example:
Performance data is archived twice for an XP or a P9000 disk array. The first set of performance
data is archived for the date range, 2009-01-01 12:10:00.109 TO 2009-04-01
09:10:00.109. The second set of performance data archived for the date range, 2009-03-
01 12:10:00.109 TO 2009-05-01 09:10:00.109. Then, the first set of data is imported
to a target management station. When you try to import the second set of data to the same target
management station, P9000 Performance Advisor prompts you to either archive or purge the ex-
isting data, and then import the second set of data again.
This is because, the performance data already exists in the P9000 Performance Advisor database
for the date range, 2009-03-01 12:10:00.109 TO 2009-04-01 09:10:00.109. So,
first archive or purge the existing performance data for the date range, 2009-03-01 12:10:00.109
TO 2009-04-01 09:10:00.109, and then import the second set of performance data again.
• After data is imported onto the target management station, you can only use the remaining TB-
Days of Meter based Term license that are available after the data is exported from the source
management station.
For example, if you installed 100TB-Days of Meter based Term license on the source management
station to monitor an additional usable capacity of 10TB for 10 days and 80TB-Days are used
before you exported the data, only 20TB-Days are available when data is imported onto the target
management station.
Importing archived data to the same management station
To import the archived data to the same management station:
1. Click PA and DB Settings > Database Manager in the left pane.
2. On the Database Manager screen, click the Archive Export/Archive Import tab.
