HP StorageWorks XP Performance Advisor Software v4.6 User and Troubleshooting Guide (T1789-96094, June 2010)

IMPORTANT:
Following are a few important notes:
• After importing performance data for an XP array, ensure that you perform a fresh configuration
data collection for that XP array on the target management station. This is because, the archival
process only exports the performance data for an XP array and not its configuration data. For
example, if you import performance data for an XP array that is not currently known to XP Per-
formance Advisor on the target management station, you cannot view its performance data until
a configuration collection is performed for that XP array.
Also, if data is imported for XP10000, XP12000, XP20000, or XP24000 disk array model into
XP Performance Advisor v4.6, 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 shown by RWC) when compared to the value
received through the Inband mode. So, if the SVP on the XP Disk Array is accessible, Outband
must be the preferred mode of configuration data collection. It ensures that XP Performance Advisor
collects the correct internal raw disk capacity from your XP Disk Array. The internal raw disk ca-
pacity for your 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 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,
XP Performance Advisor prompts you to either archive or purge the existing data, and then import
the second set of data again.
This is because, the performance data already exists in the XP Performance Advisor database for
the date range, 2009-03-01 12:10:00.109 TO 2009-04-01 09:10:00.109. So, you
should 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.
Importing archived data to the same management station
To import the archived data to the same management station:
1. Click Database Manager in the left pane.
2. On the Database Manager screen, click the Archive Export/Archive Import tab.
