Commit Active Storage Region Changes

Use this procedure to verify and commit active storage region configuration changes you have made on the Select Active Cells page.  This procedure warns you of the following possible errors:

• The library has orphaned cartridges.

• Cells will be made inaccessible to library hosts.

Caution – Possible configuration conflicts. Although changes to active capacity are not disruptive to library hosts, it is recommended that you make the library unavailable to other users before committing
your active storage region changes. Because the SL Console does not validate storage region boundaries against the library controller database in real-time, configuration conflicts may arise if you
change active storage region boundaries while other users are performing cartridge movements or library configuration changes.
See “Synchronizing the Display With the Controller Database” for details.

Solution

 Task Steps

1. Perform the steps in “Define Active Storage Regions” .
The changes you have made are displayed on the Select Active Cells page.

2. In the upper right corner, click Apply.
The boundaries of the active storage regions are verified, including the locations of all tape cartridges.

Note – The system performs this verification only on the active storage region configuration defined in the Select Active Cells screens. It does not verify active storage regions against the library controller database. Therefore, it cannot identify configuration conflicts that may arise due to other users performing cartridge movements or library configuration changes (through the command line interface, other SL Console sessions, or host applications) at the same time you have made changes to active storage regions.
The Confirm Apply message appears, indicating whether there are any orphaned cartridges or other problems in the active storage region configuration.

3. To display detailed warning messages explaining the reasons for any orphaned cartridges, click Details.
You can use the Details button to toggle between the expanded and collapsed views of the warning messages.

4. Optionally, in the expanded view of the warning messages you can do the following:
• Click PRINT to print the detailed message data.
• Click SAVE TO FILE to save the detailed message data to a comma-separated file.

5. Proceed as follows:
• Click No to cancel the update.
The library controller database is not updated, but all changes you have made are retained on the Select Active Cells page.
• Click Yes to make the following updates to the library controller database and proceed to Step 6.
• White cells with a turned over (“dog-eared”) left corner are made inactive.
• Purple cells without a turned over (“dog-eared”) left corner are made active, up to the total activated capacity of the library. Purple cells that cannot be made active due to library activated capacity limits will remain purple and will automatically become active whenever additional activated capacity is installed.
• All other cells are left unchanged.
• The Commit Success message appears.

6. Click OK to return to the Select Active Cells page.
All newly activated cells are immediately available for use. The library does not need to be rebooted.

7. All affected library host applications must now be configured to recognize these updates. See the appropriate tape management software documentation for the procedures and commands.
