The Sun Cluster Geographic Edition software internally creates and maintains one replication resource group for each protection group. The name of the replication resource group has the following format:
rg-tc_truecopyprotectiongroupname |
If you add a Hitachi TrueCopy device group to a protection group, Sun Cluster Geographic Edition software creates a resource for each device group. This resource monitors the status of replication for its device group. The name of each resource has the following format:
r-tc-truecopyprotectiongroupname-truecopydevicegroupname |
You can monitor the status of replication of this device group by checking the Status and Status Message of this resource. Use the scstat -g command to display the resource status and the status message.
The following table describes the Status and Status Message values that are returned by the scstat -g command when the State of the Hitachi TrueCopy replication resource group is Online.
