When you select this option, the library automatically runs a series of diagnostic tests on library drives with encryption capability. These tests are run in sequence, in the order in which they appear on the results page. If a drive passes a test, the system displays "Passed" and continues on to the next test in the row. Subsequent tests are run even if the ping test fails. These tests may take a few minutes to run.
If you configure Key Path Diagnostics for Periodic KPD you have the option to change the Test Interval. You also have the option to enable Test Delay Reporting and to change the Test Delay Reporting Threshold.
Using Periodic Key Path Diagnostics
You can enable the library to automatically perform Key Path Diagnostics at selected intervals. During each interval the library tests every configured key server. The default test interval is four hours. The library generates a RAS ticket if there are problems.
Periodic Key Path Diagnostics is disabled by default. It is recommended that you leave Periodic Key Path Diagnostics disabled unless network interruptions are a common cause of encryption failures at your site.
Attention: Running Periodic Key Path Diagnostics may cause an increase in RAS tickets if tests are skipped due to tape drives being unavailable for a configurable number of consecutive test intervals. To reduce the occurrences of RAS tickets, you can specify the number of consecutive test intervals required to generate a RAS ticket to a higher number, or you can set the library to never generate an RAS ticket for missed test intervals.
To enable Periodic Key Path Diagnostics:1. From the web user interface select Service Library: Key Path Diagnostics.
2. Select Enable Periodic Key Path Diagnostics.
3. Select a test interval from the Test Interval list.
4. Check Enable Test Delay Reporting if you want the library to generate an RAS ticket to inform you that the test could not be performed within the specified number of test intervals. If you check Enable Test Delay Reporting from the Test Delay Reporting Threshold list, select the number of consecutive, missed test intervals that are required before the library generates an RAS ticket. You can select any value from 1 to 24. The default threshold is 3. If you do not check Enable Test Delay Reporting the library will never generate an RAS ticket no matter how many tests are missed.
