To avoid any loss of critical data, it is essential for a disk array to always maintain a pool of spare disks that can replace the faulty disk when a disk failure occurs. A disk array without any left spare disk will not be able to keep the level of data safety and performance in case of a disk failure.
The SpareDiskCount parameter of the SEN_EMC_ARRAY class reports the number of spare disks available for each disk array monitored with the solution. By default, a warning is triggered when no spare disk is available (SpareDiskCount is set to zero).
Verifying the number of available spare disks in all your EMC disk arrays
| 1. | Create a PATROL Query in the PATROL Console to show the value of the SpareDiskCount parameter of the SEN_EMC_ARRAY class; In the main menu bar, click Actions > New Query… |
PATROL Query – General Tab
| 2. | Enter the Query name (example: Available Spare Disks) |
| 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 section, 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_EMC_ARRAY |
PATROL Query – Application Class Tab
| 9. | In the Pattern Matching section, select Like and type SpareDiskCount |
PATROL Query – Parameter Tab
| 10. | Click OK to display a table with the number of spare disks available in each monitored disk array. |
