The execution results of relocation can be confirmed by referring to the relocation history. Refer to "Display Capacity Detail Information" in the ETERNUS SF Web Console Guide for how to display relocation history of Tier pool or FTV.
Information
If relocation is not executed on completion of Automated Storage Tiering evaluation for a multiple layer Tier pool, no relocation history based on the evaluation result exists and the generation of evaluation result displayed in the access status chart does not match the generation of relocation history.
The following table shows the generation relation when relocation is not executed for the evaluation result of one generation earlier than the latest generation.
Relation Between Generation of Evaluation Result Displayed in Access Status Chart and Generation of Relocation History | |||||
|---|---|---|---|---|---|
Generation of evaluation result displays in access status chart | Four generations earlier | Three generations earlier | Two generations earlier | One generation earlier | Latest generation |
Execution of relocation after Automated Storage Tiering evaluation | Done | Done | Done | Not done | Done |
Generation of relocation history | Three generations earlier | Two generations earlier | One generations earlier | - | Latest generation |
In this table, if you specify "1 generation ago" for Generation on the Access Status Chart panel, an access status chart based on the evaluation result of one generation earlier than the latest generation is displayed. On the other hand, the relocation history of one generation earlier than the latest generation shows the one executed based on the evaluation result of two generations earlier than the latest generation.
Therefore, you must consider mutual generation relations when seeing the access status chart and the relocation history.
The items displayed as relocation history are as follows.
Item | Meaning |
|---|---|
Start Time | Time when relocation is started. |
Finish Time | Time when relocation has finished. |
Relocation Result | These are the execution results of relocation. One of the following is displayed:
"Normal Finished" is displayed when relocation has been completed successfully. Stopping relocation results in "Normal Suspended". |

Relocation history displays a maximum of five relocation results including the latest one.
The relocation result of a Tier pool can be displayed when either of the following conditions is satisfied:
Execution Mode of Automated Storage Tiering is "Auto".
Execution Mode of Automated Storage Tiering is "Semi-Auto" or "Manual", and relocation is executed from Web Console.
The latest and previous relocation results can be checked by Detail View. Refer to "Display Tier Pool" in the ETERNUS SF Web Console Guide for information on the latest relocation result and the previous relocation result.
