Repairing the system
About this task
If the checking process discovers errors of the type ProtecTIER recoverable errors,
attempt to repair the errors using ProtecTIER Manager.
Attention:
Make sure to allot sufficient down-time for system recovery. The
recovery process is time-consuming and the ProtecTIER system goes offline for the
duration of that process.
Procedure
1.
In the Categories sub-pane, select the checkbox for each category for which you
want to repair errors. All list items of the type ProtecTIER recoverable errors
in each selected category appear in the Selected errors to recover pane and are
labeled with a red X.
2.
Click Recover. ProtecTIER Manager attempts to repair the errors. Errors that
are successfully repaired are labeled with a green checkmark. Errors that cannot
be repaired remain labeled with a red X.
Note:
For assistance with errors that cannot be repaired, contact a trained
ProtecTIER specialist.
Near online check and recovery
Near online check and recovery allows you to scan your system for errors and
repair them. Once the process completes, you will be able to generate a file to help
locate the cartridges that might contain corrupted data.
Near online check and recovery process
Near online check and recovery consists of three stages:
Stage 1: Pre-Recover
This stage is performed offline. All ProtecTIER structures are scanned and
checked for inconsistency and data integrity. All STUs are checked to see if
they are in error mode or if the DSPF is damaged.
Stage 2: Dfs_map
This stage is performed online. During this stage RAM is preserved by
postponing deletes, and the process checks for data integrity in the STUs
found in error mode in the previous stage.
Stage 3: Recovery
This stage is performed offline. Damaged STUs are rebuilt and recovered.
