The Sun Cluster Geographic Edition software internally changes some properties for the SUNWscgreptc resource type. Therefore, you must not edit these properties manually.
For Hitachi TrueCopy and Universal Replicator, do not edit the following properties:
Dev_group – Specifies the Hitachi TrueCopy or Universal Replicator device group that contains the volumes that are being replicated.
Replication_role – Defines the local data replication role.
