Data Domain: Migration Send Fails due to Destination Hostname Mismatch

Migration send fails with errors similar to:

WARNING: _cmd_migration_are_serious_alerts_active() 1088 : Send cannot continue, found serious alert active.
MSG-DDSH-00017: command "migration send all destination-host DATADOMAIN-migration.example.com" exited with code: 33

Active alert:

EVT-REPL-00005: Replication destination not configured

The migration was initiated using the destination hostname: DATADOMAIN-migration.example.com.

Example:

migration send all destination-host DATADOMAIN-migration.example.com

However, the destination replication context was created using: DATADOMAIN.example.com.

Example:

Replication configuration example: repl.000.dst_host = DATADOMAIN.example.com

During migration, Tech Refresh migration searches for an existing replication context based on the destination hostname configured in the context (dst_host). Since the migration command specified a different hostname, no matching replication context could be found.

Example log entries:

no matching context for DATADOMAIN-migration.example.com
Replication (DATADOMAIN-migration.example.com) not configured on the replica

As a result, the migration send operation fails and reports that replication is not configured.

Configure local host entries for the migration hostnames to use the preferred interfaces and avoid hostname conflicts.

Examples:

net hosts add x.x.x.220 datadomain01-migration.example.com datadomain01-migration
net hosts add x.x.x.61 DATADOMAIN-migration.example.com DATADOMAIN-migration

To resolve the issue, use one of the following options:

• Execute the migration send command using the same hostname that was used when the destination replication context was created.
• Recreate the destination replication context using the desired hostname and corresponding host entries.
