Pinned Track Recovery for TCz Volumes
To ensure full data integrity of the pair while recovering the pinned track, use the following
procedure:
1. Connect to the MCU of the TCz pair which contains the volume with the
pinned track, and select the correct CU.
2. Release the TCz pair which contains the volume with the pinned track.
Note: If you release the TCz Asynchronous pair, release only pair which
contains the volume with the pinned track. To release only TCz Asynchronous
pair which contains the volume with the pinned track, select Volume for
Asynchronous Parameters and Delete Range.
3. Perform your usual procedure for recovering data from a pinned track. Refer
to the pinned track recovery procedures for your OS. Please contact your
Hitachi Support Center to inform them of the pinned track.
4. Restart the pair using the Add Pair dialog box, making sure to use Entire
Volume initial copy option.
Note: Make sure to specify the pair for which the pinned track recovery
operation was performed.
