Reporting Disk Space Consumption

Making sure that a filer has enough remaining disk space available is critical for several reasons:

•SAN administrators want to make sure to be able to provision disk space for new servers and users when requested, as quickly as possible.

•The filer itself may need additional disk space for specific features to work properly, like automatic snapshots, mirroring, etc.

•Users and applications actively using a share on the filer will surely be severely impacted by the fatal "File system is full" error message

The disk space used is permanently monitored for each aggregate and each volume with the SEN_NA_AGGREGATE and SEN_NA_VOLINFO classes.

By default, a warning is triggered on the FreeSpacePercentage parameter when it goes below 10 %, and an alarm is triggered when it goes below 1%.

Reporting Disk Space Consumption on a Volume and an Aggregate

1.Create a PATROL Query in the PATROL Console to show the value of the FreeSpacePercentage parameters of the SEN_NA_AGGREGATE and SEN_NA_VOLINFO classes; In the main menu bar, in the Patrol Central Operation Taskpad, click the New Query icon or open the Actions menu and click New Query.

PATROL Query – General Tab

2.Enter the Query name (example: Space Disk Consumption)

3.Enter the Query description (optional)

4.In the Query Results Filter section, select Show Selected Objects and check the Parameters box

5.In the Additional Filtering, select the Enable Parameter level filtering option

6.Open the Parameter tab and, in the Pattern Matching section, select Like and type FreeSpacePercentage.
