Replserverguid

Edit online

The replserverguid option specifies the globally unique identifier (GUID) that is used when the client connects to a failover server. The GUID is used to validate the failover server to ensure that it is the expected server.

The replication GUID is different from the machine GUID of the server. It is generated one time for a server that is doing the replication and never changes.

This option must be specified within a replservername stanza in the client options file. The replservername stanza contains connection information about a failover server.

This option is set by the IBM Storage Protect server administrator for the client node. During the normal (non-failover) logon process, the option is sent to the client and is saved in the client options file.

Do not edit this option during normal operations.

Edit this option only during situations such as the following ones:

The primary server is offline and the information for a failover server is not in the options file.
The failover server information is out-of-date or incorrect.

Any values that you edit are removed or updated the next time that you log in to the primary server.

Supported Clients

This option is valid for all clients.

Syntax

Parameters

serverguid: Specifies the GUID of a failover server.

Examples

Options file:

REPLSERVERGUID 91.0f.ef.90.5c.cc.11.e1.ae.34.08.00.00.00.00.02

Command line:

Does not apply.

Options file:

The following example demonstrates how to specify options for multiple failover servers servers in the dsm.sys file, and how to reference the failover servers.

Connection information for multiple failover servers is presented in stanzas. Each stanza is identified by the replservername option and the name of a failover server.

The servername stanza must contain the myreplicationserver option, which points to up to two failover servers that are specified by replservername stanzas.

Options file:

The following example demonstrates how to specify options for multiple failover servers in the dsm.opt file, and how to reference the failover servers.

The connection information for each failover server is located within a REPLSERVERName stanza.

The MYREPLICATIONServer option points to up to two failover server names that are specified by the REPLSERVERName stanzas.

    REPLTCPSERVERADDRESS TargetReplicationServer1
