| gnr_array_vanished | INFO_DELETE_ENTITY | INFO | no | Message: A GNR declustered array {0} has vanished. |
| Description: A GNR declustered array that is listed in the IBM Storage Scale configuration was not detected. | ||||
| Cause: A GNR declustered array that is listed in the IBM Storage Scale configuration, which was mounted before, is not found. This could be a valid situation. | ||||
| User Action: Run the mmlsrecoverygroup command to verify that all expected GNR declustered arrays exist. | ||||
| gnr_da_out_of_space | STATE_CHANGE | ERROR | FTDC upload | Message: The GNR declustered array {id} is reporting zero disk space is available. |
| Description: A GNR declustered array has zero free disk space remaining. | ||||
| Cause: A GNR declustered array is being actively filled with data and now has zero free disk space remaining. | ||||
| User Action: Inspect the available disk space of the GNR declustered array to remove unused files. Check the mmfs.log.latest log for any warning messages. | ||||
| gnr_da_space_critical | STATE_CHANGE | WARNING | FTDC upload | Message: The GNR declustered array {id} has reached its critical free disk space threshold. |
| Description: A GNR declustered array has reached its critical free disk space threshold. | ||||
| Cause: A GNR declustered array is being actively filled with data and has reached its critical free disk space threshold. | ||||
| User Action: Inspect the available disk space of the GNR declustered array to remove unused files. Check the mmfs.log.latest log for any warning messages. | ||||
| gnr_da_space_healthy | STATE_CHANGE | INFO | no | Message: The GNR declustered array {id} now has no disk space issues. |
| Description: A GNR declustered array that previously reported disk space issues is now reporting no disk space issues. | ||||
| Cause: N/A | ||||
| User Action: N/A | ||||
| gnr_da_space_low | STATE_CHANGE | WARNING | no | Message: The GNR declustered array {id} has reached its low free disk space threshold. |

| Cause: N/A | ||||
| User Action: N/A | ||||
| gnr_rebuild_critical | STATE_CHANGE | WARNING | no | Message: The GNR declustered array {id} executes background task {0}. Further disk failures in this array may create data loss. |
| Description: A GNR declustered array's background task is critical rebuild. | ||||
| Cause: A critical rebuild is executed on a GNR declustered array. | ||||
| User Action: Wait until the rebuild is done. Do not shutdown the related recovery group server for maintenance. | ||||
| gnr_rebuild_deferred | STATE_CHANGE | WARNING | no | Message: The rebuild task of GNR declustered array {id} is deferred for 20 minutes since a node was suspended. |
| Description: A GNR declustered array's rebuild task is deferred. | ||||
| Cause: Suspending a node results in a defer of 20 minutes for a non-critical rebuild of a recovery group. | ||||
| User Action:After suspending a node, the rebuild task is deferred for 20 minutes. After node maintenance is finished, run the mmvdisk recoverygroup change --resume <recovery group> -N <node> command. | ||||
| gnr_rebuild_error | STATE_CHANGE | WARNING | no | Message: The rebuild task of GNR declustered array {id} failed. |
