IBM Tivoli Storage Manager, Version 7.1

Disabling and enabling outbound or inbound sessions

Disabling outbound or inbound sessions can be useful if, for example, you plan a network outage that affects communication between source and target replication servers. Disabling and enabling sessions affects not only node replication operations but also certain other types of operations.

About this task

To display the status and direction of sessions for a particular server, issue the QUERY STATUS command.

Remember:

When you disable sessions for a particular server, you disable the following types of sessions in addition to replication:
- Server-to-server event logging
- Enterprise management
- Server registration
- LAN-free sessions between storage agents and the Tivoli® Storage Manager server
- Data storage that uses virtual volumes
If you disable only outbound sessions on a source replication server, data that belongs to client nodes that store data on the source replication server do not have their data replicated. However, inbound sessions to the target replication server can occur.
If a server is the target for multiple source replication servers and you disable outbound sessions on a single source replication server, the target replication server continues to receive replicated data from the other source replication servers.

To disable and enable replication sessions:

Procedure

Between a single source replication server and a single target replication server:
- To disable sessions, issue one of the following commands:
  - On the source replication server:
```
disable sessions server target_server_name direction=outbound
```
  - On the target replication server:
```
disable sessions server source_server_name direction=inbound
```
- To enable sessions:
  - If outbound sessions to the target replication server are disabled on the source replication server, issue the following command on the source replication server:
```
enable sessions server target_server_name direction=outbound
```
  - If inbound sessions from the source replication server are disabled on the target replication server, issue the following command on the target replication server:
```
enable sessions server source_server_name direction=inbound
```
Between multiple source replication servers and a single target replication server:
- To disable sessions, issue one of the following commands:
  - On the source replication servers:
```
disable sessions server * direction=outbound
```
  - On the target replication server:
```
disable sessions server * direction=inbound
```
- To enable sessions:
  - If outbound sessions to the target replication server are disabled on the source replication servers, issue the following command on the source replication servers:
```
enable sessions server * direction=outbound
```
  - If inbound sessions to the target replication server are disabled on the source replication servers, issue the following command on the target replication server:
```
enable sessions server * direction=inbound
```
