Required node names for basic VSS operations
VSS operations require specific node name settings.
To process basic VSS operations, you must
have one target node and one agent node.
| Proxy node type | Node name | Where to specify |
|---|---|---|
| Target node | The Data Protection for Exchange ServerData Protection for SQL Server node name | Use the nodename option in the Data Protection for Exchange ServerData Protection for SQL Server options file (dsm.opt) |
| Agent node | The Local DSMAGENT Node name that must match the VSS requestor node name | Use the localdsmagentnode parameter in the Data Protection for Exchange ServerData Protection for SQL Server configuration file (tdpexc.cfg)(tdpsql.cfg) |
- Target node
- The target node name specifies the name of the node that owns the Data Protection for Exchange ServerData Protection for SQL Server backup data on the IBM Storage® Protect server. This node name is specified with the nodename option in the Data Protection for SQL Server dsm.opt file and is referred to as the Data Protection for Exchange ServerData Protection for SQL Server node name.
- Agent node
- The agent node name specifies the name of the node operating for the target node. This node is
responsible for processing the VSS operations
as Data Protection for Exchange ServerData Protection for SQL Server does not process any direct
VSS operations.
This node name is referred to as the Local DSMAGENT Node and is specified with the localdsmagentnode parameter in the Data Protection for Exchange ServerData Protection for SQL Server configuration file (tdpexc.cfgtdpsql.cfg by default). You can use the Properties window of Microsoft™ Management Console (MMC) by selecting VSS backup. From here, you can update the Local DSMAGENT Node name. Otherwise, use the tdpexcc settdpsqlc set command to specify this parameter.
Tip: The agent node and target node are in a proxy relationship, and are
used for VSS operations on the SQL server that is being protected.
