• First determine which volume has troubles

 TSM> select volume_name,write_errors,read_errors,access,STGPOOL_NAME from volumes where error_state<>'No' and ( WRITE_ERRORS>0 or READ_ERRORS>0 )

• Put the volmue access in destroy status

 TSM> update vol <volume_name> access=destroy

• Checkout the volume from lib inventory

 TSM> checkout libvol <library_name> <volume_name> 

• Search for K7 needed to restore the defect volume

 TSM> restore vol <volume_name> preview=yes

• Check into activity log if all required K7 are avalaible into the library, and that enough scratch are available

 TSM> restore vol <volume_name> 

• Delete the old defect volume

 TSM> delete vol <volume_name> discard=yes

On source server do the following:

If the setting for recovering damaged files is OFF, turn it on by issuing the SET REPLRECOVERDAMAGED command and specifying ON:

set replrecoverdamaged on copy to clipboard

If the REPLRECOVERDAMAGED system parameter is set to OFF, and you change the setting to ON, an automatic scan of the Tivoli Storage Manager system is started. You must wait for the process to be completed successfully before you can initiate the recovery of damaged files by using the REPLICATE NODE command. Recover damaged files by running the REPLICATE NODE command and specifying a value for the RECOVERDAMAGED parameter. Take one of the following actions:

  To run the full node replication process and recover damaged files, specify the name of the node or node group, and the RECOVERDAMAGED parameter with a value of YES.
  For example, to run the full node replication process and recover damaged files for client nodes in the PAYROLL group, issue the following command:

  replicate node payroll recoverdamaged=yes
  copy to clipboard

  To run the node replication process only to recover damaged files, specify the name of the node or node group, and the RECOVERDAMAGED parameter with a value of ONLY.
  For example, to recover damaged files for client nodes in the PAYROLL group without running the full node replication process, issue the following command:

  replicate node payroll recoverdamaged=only
  

• First delete the volume, and checkout from library

 TSM> delete vol <volume_name> discard=yes
 TSM> checkout libvol <library_name> <volume_name> remove=bulk

• Restore the volume from primary stgpool

 TSM> backup stgpool <primary_stgpool> <secondary_stgpool>
