Automatically purging data
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.
