HP XP P9000 Performance Advisor automatically purges performance data that belongs to XP and
P9000 disk arrays, if either of the following conditions are met:

•

The auto grow functionality is enabled but sufficient free disk space is not available.

•

The auto grow functionality is disabled and the database grows to 70% of the allocated
database size.

•

The database has grown to 300 GB that is the maximum database size that can be allocated.

For the above-mentioned conditions, the following prediction on when auto purge will start is also
displayed in the Purge section: Given current data storage rates, in X days/hours, auto-purging
will begin.

The following message is logged on the Event Log screen when auto purging is activated: Activating
Purge Mode.

When auto purge is in progress, the following message is displayed in the DB Configuration section
under the DB Configuration/Purge tab: Given current data storage rates, the estimate is less than
X hours, auto purging may have already begun.

The following message is also displayed on the Event Log screen: Purge or migration is in progress,
please retry after some time.

After auto purging completes, the following message is logged in the Even Log file: Auto Purge
completed successfully.

IMPORTANT:
•

When auto purging is in progress and you manually increase the database size, the auto
purging process stops. The following message is logged on the Event log screen:

Autopurging interrupted due to DB size change.

•

Auto purging procedure also defragments the allocated database space, so that the free space
is released back to the database.
