0xF0DD0001 Remote Replication Consistency Group Is Disconnected
Applicable Model
Applicable to all models.
Impact on the System
The consistency group is disconnected due to link disconnection between two storage arrays. If the links cannot be recovered, the consistency group must be deleted.
Possible Causes
- Links are unstable.
- The disk domain is faulty.
- The primary LUN of the remote replication is faulty.
- The secondary LUN of the remote replication is faulty.
- The storage pool is full.
Procedure
- Check whether cables are securely inserted.
- Check whether an alarm is generated for the storage pools to which the primary and secondary LUNs belong.
- Check whether an alarm is generated for the primary and secondary LUNs or their disk domains.
- Check whether an alarm is generated indicating controller overload.
- Check whether an alarm is generated indicating degraded links.
- Check whether the member LUNs of the consistency group are in write-through status or write protection status.
- If yes, collect related information and contact technical support engineers.
- If no=> Step7.
- Collect related information and contact technical support engineers.
