Verifying migration volumes after a system recovery

If system recovery occurred while volumes were being migrated between two systems with non-disruptive volume migration, volumes are recovered based on where in the migration process that the system recovery occurred.

After a system recovery, use the following information to determine recovery actions for volumes that are associated with non-disruptive volume migration.

System recovery on the source system before the switch
  • The migration relationship is deleted on the source system.
  • The partnership is removed on the source system.
  1. Delete the auxiliary volume from the target system in the migration relationship with the management GUI or the rmvolume command.
  2. Recover the source volume, potentially from tape.
  3. If you want to recover all the data in migration relationships that are consistent_synchronized at the time of the system recovery, contact support. This recovery can be a lengthy process.
System recovery on source system after the switch
  • The migration relationship is deleted on the source system.
  • The partnership is removed on the source system.
  • The UUID of the source volume is changed.
  • Any host mappings to the source volume in the migration relationship are removed.
  1. Delete the source volume with the management GUI or the rmvolume command.
  2. Delete the migration relationship on the target system with the management GUI or the rmrcrelationship command.

  2. Remove the migration relationship from the source system with the management GUI or the rmrcrelationship command.
