Hi to all

In TSM Version 7.1.1+ there is a new feature called  SET REPLRECOVERDAMAGED

To use it need to be ON with the command:  SET REPLRECOVERDAMAGED  ON

Here the help below but don’t understand what is the default  YES or NO ?
During a replicate node.

RECOVERDamaged--=--+-Yes--
                                                +-No---
                                                +-Only-

RECOVERDamaged
   Specifies whether a recovery process is started on a target
replication
server after the node replication process is completed.
   This parameter is optional, and it overrides any value that you
specified
for the RECOVERDamaged parameter when you defined or  updated a node. You
can
specify one of the following values:

   Yes
      Specifies that a replication process is started to recover damaged
files, but only if the setting for the REPLRECOVERDAMAGED system
      parameter is ON. If the setting is OFF, damaged files are not
recovered.

   No
      Specifies that damaged files are not recovered.

   Only
      Specifies that a replication process is started for the sole purpose
of
recovering damaged files, but only if the setting for
      the REPLRECOVERDAMAGED system parameter is ON. If the setting is
OFF, damaged files are not recovered, and you receive a  notification that
recovery was not started.

Based on what I read, the broader question seems to be... When you run the
REPLICATE NODE command, will damaged files be recovered by default?

The answer depends on several factors. As mentioned in the REPLICATE NODE
command topic:

"Files are recovered only if all the following conditions are met:
Tivoli® Storage Manager, Version 7.1.1 or later, is installed on the source
and target replication servers.
The REPLRECOVERDAMAGED system parameter is set to ON. The system parameter
can be set by using the SET REPLRECOVERDAMAGED command.
The source server includes at least one file that is marked as damaged in
the node that is being replicated.
The node data was replicated before the damage occurred."

In addition, the recovery of damaged files depends on the setting for the
RECOVERDAMAGED parameter for the individual node. See Table 1 in the
REPLICATE NODE topic:
