Sun Storage Availability Suite - Version 3.0 and later
All Platforms

Symptoms

 

After a short network outage in the network path used for StorageTeK Network Data Replication (SNDR) between the SNDR-master and the SNDR-slave.

Normally system administrators would expect the replication to resume automatically once the network link recovers.

The expected state would be "replicating" if replication had resumed after the network outage.

 

Changes

 

When the replication set was originally configured, the administrator did not setup the replication to automatically resume

after any network outages are fixed.
