Making sure that a disk array 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 when requested, as quickly as possible. |
| • | The disk array itself may need additional disk space for specific features to work properly, like automatic snapshots, mirroring, etc. |
The ConsumedCapacity parameter of the SEN_I345_ARRAY class represent the actual space usage in the disk array.
The ConsumedCapacityPercentage parameter is the most critical one, as a disk array usage nearing 100% means that SAN administrators will not be able to create new logical drives. By default, no alarm or warning threshold is set on this parameter as the fullness of a disk array may be a normal situation.
Verifying the available disk space in several disk arrays
| 1. | Create a PATROL Query in the PATROL Console to show the value of the ConsumedCapacityPercentage parameter of the SEN_I345_ARRAY class; In the main menu bar, click Action > New Query… |
PATROL Query – General Tab
| 2. | Enter the Query name (example: DiskSpaceConsumption) |
| 3. | Enter the Query description (optional) |
| 4. | In the Query Result Filter section, select Show Selected Objects and check the Parameters box |
| 5. | In the Additional Filtering, select the Application Class level filtering and the Enable Parameter level filtering options |
| 6. | Open the Application Class tab |
| 7. | In the Pattern Matching section, select Like and type SEN_I345_ARRAY |
PATROL Query – Application Class Tab
| 9. | In the Pattern Matching section, select Like and type ConsumedCapacityPercentage |
PATROL Query – Parameter Tab
| 10. | Click OK to display a table with the amount of actually consumed capacity in all of the disk arrays of your monitored IBM environment. |
