Snapmirror Relationship Statuses
| RELATIONSHIP STATE | MEANING | NOTES |
| Idle | No transfer operation is in progress and future transfers are not disabled. | This is a normal State that does not need corrective action. |
| Queued | A transfer operation has been accepted and queued in the system, and future transfers are not disabled | |
| Transferring | A transfer operation is in progress and future transfers are not disabled. | You can use snapmirror abort to Stop a in progress transfer. This will place the Mirror in a unhealthy state and back into Idle. |
| Preparing | Pre-transfer phase for incremental transfers. For SnapMirror Type-XDP relationships only. | This is a System Process. If a relationship is spending an excessive amount of time Preparing, please contact the support team for assistance. |
| Finalizing | Post-transfer phase for incremental transfers. Network traffic will be low as processing is primarily on the destination volume. For SnapMirror Type-XDP relationships only. | This is a System Process. If a relationship is spending an excessive amount of time Finalizing, please contact the support team for assistance. |
| Aborting | A transfer abort operation that may include the removal of the checkpoint is underway. Future transfers are not disabled. Only for relationships with "Relationship Capability" of "8.2 and above". | |
| Quiesced | No transfer operation is in progress and future transfers are disabled. | Snapmirror resume can be used to resume scheduled updates. |
| Quiescing | A transfer operation is in progress and future transfers are disabled. | Quiescing can take a while on Vault relationships, however if excessive please contact the Support team for assistance. |
| Checking | Destination volume is undergoing a diagnostic check, no transfer is in progress, and future transfers are not disabled. Only for relationships with "Relationship Capability" of "Pre 8.2". | This is a System Process. If a Vault relationship is spending an excessive amount of time Checking, please contact the support team for assistance. |

Snapmirror Mirror States
| MIRROR STATE | MEANING | NOTE |
| Uninitialized | Destination volume has not been initialized. |
This is the default state when a relationship is created. The mirror will show un-initialized until the initialization completes successfully. |
| Snapmirrored | Destination volume has been initialized and is ready to receive SnapMirror updates. |
|
| Broken-off | Destination volume is RW and snapshots are present. | Breaking off a relationship changes it to become read/writable and allows you to use it like a normal volume. To put the volume back into a Snapmirrored state you will need to use the Snapmirror resync command. This is dependent on the relationship having a common snapshot, if it does not the source volume will have to be reprotected. |
