Recovering a Pinned Track on a Journal Volume
If a pinned track occurs on a URz master or restore journal volume, the
procedure for pinned track recovery is as follows:
1. Identify the journal group that contains the journal volume where a pinned
track occurs. After that, split the mirror where the journal group belongs.
2. Delete the journal volume containing the pinned track from the journal
group.
3. Format the journal volume by using the LDEV format function of VLL. For
detailed instructions on how to format the volume, please refer to Virtual
LVI/LUN and Volume Shredder User's Guide.
4. Register the formatted volume (or another volume that can be used
instead of the formatted volume) in the journal group.
If you do not need to resume copying, the procedure is now finished.
If you want to resume copying, please continue to restore the mirror to which
the journal group belongs (see section
Restoring a Mirror (Resuming a copy
operation))
