Attempting to add a replication target for Automated Image Replication (AIR) fails with the error message: database system error (220) Replication target configuration is not supported for PureDisk Storage Server.

Problem

When attempting to add a "replication target" for Automated Image Replication (AIR), an error is returned: database system error (220) Replication target configuration is not supported for PureDisk Storage Server XXX.

Error Message

Database system error (220) Replication target configuration is not supported for PureDisk Storage Server

Cause

This error message is displayed because the storage server being added as a replication target is *already configured* in the local NetBackup environment as an existing storage server.

Solution

To resolve the error, the replication target must be a storage server that is not part of the source NetBackup environment. Another storage server (part of a different NBU environment) must be selected for AIR or the existing storage server must first be removed from the source NBU environment before being added as a replication target.

Another possibility: a machine alias exists in the form of the remote target storage server's hostname for the local source storage server. To confirm, execute:

nbemmcmd -machinealias -getaliases -machinename source_storage_server_hostname -machinetype ndmp

nbemmcmd -machinealias -getaliases -machinename source_storage_server_hostname -machinetype media

Note the output of either command above should only report aliases that match the source storage server hostname or one or more of it's valid IP addresses. The outputs should not report the remote target storage server hostname.

If the aforementioned command outputs include the remote target storage server hostname, remove the alias via:

nbemmcmd -machinealias -deletealias -alias remote_target_storage_server_hostname -machinetype ndmp

nbemmcmd -machinealias -deletealias -alias remote_target_storage_server_hostname -machinetype media 

Note: The directory path for all of the commands above is...

UNIX/Linux: /usr/openv/netbackup/bin/admincmd/
Windows: install_path\NetBackup\bin\admincmd\
