Verifying a node replication setup before processing

Before you start a replication process, you can display the controlling replication rules for data types in the file spaces of client nodes that are configured for replication. You can also verify the connection to the target replication server.

About this task

A controlling rule is the rule that the source replication server uses to replicate data in a file space. For example, suppose the replication rule for backup data in file space /a is DEFAULT. If the client-node rule for backup data is ALL_DATA, the controlling rule for the backup data in file space /a is ALL_DATA.

Procedure

To validate a replication configuration, complete one of the following steps:

To display a list of file spaces and the controlling replication rules that apply to the file spaces, issue the VALIDATE REPLICATION command. For example, to display the controlling replication rules that apply to data types in the file spaces for NODE1 and NODE2, issue the following command:
```
validate replication node1,node2
```
All file spaces are displayed regardless of whether the state of the data types in the file spaces is enabled or disabled.
To display the controlling replication rules and verify the connection with the target replication server, issue the following command:
```
validate replication node1,node2 verifyconnection=yes
```

What to do next

To preview results, complete one of the following steps:

To display the following information, issue the REPLICATE NODE command and specify PREVIEW=YES
- The names of client nodes to be replicated
- The number of files to be replicated, deleted, or updated
- The estimated time to complete the process
- The tape volumes to be mounted
For example, to display the estimated time to complete the replication process for a defined group of nodes, NODEGRP1, issue the following command:
```
replicate node nodegrp1 preview=yes
```
To display a list of files to be replicated, issue the REPLICATE NODE command and specify PREVIEW=YES LISTFILES=YES. For example, to display a list of files to be replicated for NODEGRP1, issue the following command:
```
replicate node nodegrp1 preview=yes listfiles=yes
```
Specifying the LISTFILES parameter signifies that the WAIT parameter is set to YES and that you cannot the issue the WAIT parameter from the server console.

Remember: Information is displayed only if the following conditions are true:

Data types in file spaces are enabled for replication. For example, suppose that a file space contains backup and archive files and that replication of backup data is enabled. Replication of archive data is disabled. In this case, only information about backup files is displayed.
Client nodes are enabled for replication.
If the controlling replication rule is a server rule, the server rule must be enabled.
