• The Manual diagnostics takes affected partitions offline. The Automatic diagnostics does not take
partitions offline. It may delay moves to tape drives while they are being tested.
• The Manual EKM Path Diagnostics requires that you select one tape drive to use for the test. Since the test
only validates the selected drive, if you want to test the path for each tape drive, you must run the test
multiple times (once for each drive). To test all servers, you must run the diagnostics once for each Library
Managed Encryption enabled partition (each server pair is connected to a unique partition and tape drive).
If the tape drive is not available (it must be unloaded, ready, and online), the Drive, Path, and Config tests
are not performed.
• The Automatic EKM Path Diagnostics tests every connected EKM server in turn, and the library selects the
tape drive to use for each test. If the selected tape drive is not available (it must be unloaded, ready, and
online), then the library tries another tape drive that is connected to the key server until it finds one that is
available. If no tape drives connected to a particular key server are available, then that server is skipped and
the tests are not performed. If a server is skipped for “X” number of consecutive test intervals (where “X” is
configurable on the Web client), the library generates a RAS ticket. If a tape drive remains loaded for a long
time, it is possible that it will never be tested. If you want to test a specific tape drive, then you should use
the Manual EKM Path Diagnostics. In particular, if you replace a tape drive, run the Manual EKM
path diagnostics.
Manual EKM Path Diagnostics
1 Access the EKM Path Diagnostics screen in one of two ways:
• Enter library Diagnostics (select Tools > Diagnostics) and then select EKM > EKM Path
Diagnostics. Note that entering Diagnostics will log off all other users of the same or lower privileges
and take your partitions offline. When you exit Diagnostics, the partitions automatically come back
online.
• Select Setup > Encryption > System Configuration or Setup > Encryption > Partition
Configuration and click the link that says “Click here to run EKM Path Diagnostics.” Note that
performing this action takes the partition in which the selected tape drive resides offline. When the
test completes, the partition automatically comes back online.
A list of all the tape drives enabled for library-managed encryption is displayed, along with the tape drive
status and the partition in which each tape drive resides.
2 Select the tape drive on which you want to perform diagnostics and click Apply. The tape drive must be
unloaded, ready, and online in order for the test to run.
A dialog box appears telling you that the selected partition will be taken offline.
3 Click OK to start the diagnostics.
The Progress Window appears. The Progress Window contains information on the action, elapsed time,
and status of the requested operation.
The library performs the diagnostics and reports pass/fail results on each of the tests in the Progress
Window.
NOTE:
The diagnostics tests may take several minutes to complete.
4 Do one of the following:
• If Completed appears in the Progress Window, the diagnostics were performed (this does not mean
that the diagnostics passed, just that the diagnostics were performed). Click Close to close the Progress
Window.
• If Failure appears in the Progress Window, the diagnostics were not able to be performed. Follow the
instructions listed in the Progress Window to resolve any issues that occurred during the operation.
