Purging data
You
can manually purge configuration and performance data for an XP or an XP7 disk array, or
data
older than the current specified date. HP XP7 Performance Advisor can automatically purge
data.
For more information, see
“Automatically
purging data” (page 147)
.
•
When
you purge data for an XP or an XP7 disk array, the corresponding configuration and
performance
data are permanently removed from the database.
•
When
you purge data for a specified duration, only the performance data collected for the
XP
and the XP7 disk arrays during that duration is permanently removed from the database.
You
can continue to collect performance data for those arrays, as their configuration data still
exists
in the database.
Purging data eventually increases the performance of HP XP7 Performance Advisor, as considerable
amount of disk space used by the database is released back to the database.
Manually purging data
You
can manually purge data that belongs to an XP or an XP7 disk array, or data that is older
than
the current specified date.
CAUTION: The data that is purged cannot be recovered. It is permanently deleted from the HP
XP7 Performance Advisor database. Hence, purge data only when you are absolutely sure that
the data is no longer required. Also, HP XP7 Performance Advisor activities, such as plotting charts
and collecting data might be impacted when either the manual or auto purge is in progress.
Alternatively, if you want to archive data before purging it, use the archival export functionality.
For more information, see
“Archiving data” (page 160) .
IMPORTANT: The current date and time on your management station (where HP XP7 Performance
Advisor is installed) is considered for deleting the records.
Purging
data for XP or XP7 disk array
To
purge data from the HP XP7 Performance Advisor database for an XP or an XP7 disk array:
1. Click PA and DB Settings+Database Manager in the left pane.
The Database Manager screen appears. By default, the DB Configuration/Purge is enabled.
2. In the Purge section, select All data for array.
The drop-down list for this selection is enabled.
3. From
the list, select the XP/XP7 disk array for which you want to purge data.
4. Click Purge.
A dialog box appears prompting you to confirm the deletion of records.
5. Click Yes to confirm.
HP
XP7 Performance Advisor deletes the configuration and performance data collected till
date
for the selected XP or XP7 disk array from the database. Hence, the
XP/XP7
disk array does not appear in any of the HP XP7 Performance Advisor screens. To
view
the array details again, request update from the host connected to that XP/XP7 disk
array.
Then, perform a configuration collection followed by performance collection for that
XP/XP7
disk array. For more information, see
“Requesting
host agent updates” (page 47)
