Frequently asked questions
Sun SNDR is a software product designed for data replication across storage volumes, ensuring high availability and consistency between primary and secondary hosts.
You can enable data replication for a specific set using the sndradm -e command, which allows you to specify parameters like primary and secondary device paths, protocol, and replication mode.
You can view the status of all configured Sun SNDR replication sets and their I/O statistics using the sndradm -l command, which provides details on primary and secondary volumes.
The scmadm -S command is used to display statistical information about the Sun StorEdge Network Data Replicator's cache, including disk I/O, cache hits, and overall memory usage.
Yes, Sun SNDR can be configured to work with Sun Cluster 2.2, 3.0, and 3.0 Update 1, providing enhanced data protection and disaster recovery capabilities within a clustered environment.
