How to Cancel a Migration

If you decide, after deactivating a server group or machine, that you do not want to continue, you can cancel the migration before reactivating the server group or machine. All the information in the name server for the deactivated servers and services is deleted.

To cancel a migration after a shutdown but before issuing the migrate command, enter one of the following commands.

To Cancel . . .	Enter This Command . . .	As a Result . . .
Server migration	tmadmin migrategroup -cancel or tmadmin migg -cancel	Server entries are deleted from the bulletin board. You must reboot the servers once the migration procedure is canceled.
Machine migration	tmadmin migratemach -cancel or tmadmin migm -cancel	The migration is stopped.

Example of a Migration Cancellation

The following sample tmadmin session shows how a server group and a machine can be migrated between their respective primary and alternate machines.
