Viewing purge history
When you manually initiate a purge or HP P6000 Performance Advisor initiates an auto-purge, a
purge task is created and displayed in the table for each storage system or performance object
for which the purge is initiated. If you initiate a purge for a storage system, where all its
corresponding performance objects are selected, that many number of records are created. Only
one purge task can be in progress at a time, while others are shown in the pending state. Purge
events are logged at the start, end, and failure of purge tasks. In addition, HP P6000 Performance
Advisor initiates an auto-purge for a storage system if the storage system crosses the data retention
period. To understand purge, see
“Database maintenance” (page 31) .
