Observe the following requirements and guidelines:
If you are using storage-based replication, do not configure a replicated volume as a quorum device. The Sun Cluster Geographic Edition software does not support using a Hitachi TrueCopy or Universal Replicator S-VOL and Command Device as a Sun Cluster quorum device. See Using Storage-Based Data Replication Within a Cluster in Sun Cluster System Administration Guide for Solaris OS for more information.
If you use the Hitachi TrueCopy and Universal Replicator Command Control Interface (CCI) for data replication, you must use RAID Manager. For information about which version you should use, see the Sun Cluster Geographic Edition Installation Guide.
This model requires specific hardware configurations with Sun StorEdgeTM 9970/9980 Array or Hitachi Lightning 9900 Series Storage. Contact your Sun service representative for information about Sun Cluster configurations that are currently supported.
All Hitachi TrueCopy or Universal Replicator device groups with the same consistency group ID (CTGID) must be added to the same protection group.
Sun Cluster Geographic Edition software uses the default CCI instance to manage the Hitachi TrueCopy or Universal Replicator devices. Sun Cluster Geographic Edition software starts the default CCI instance whenever a TrueCopy device group is managed by Sun Cluster Geographic Edition software. Applications that are not under the control of Sun Cluster Geographic Edition software can also use the default CCI instance or any other instances without risk to Sun Cluster Geographic Edition or application processes or data.
Sun Cluster Geographic Edition software supports the hardware configurations that are supported by the Sun Cluster software. Contact your Sun service representative for information about current supported Sun Cluster configurations.
The Sun Cluster device groups that are listed in the cluster_dgs protection group property must exist and have the same device group name on both the primary cluster and the secondary cluster.
