PowerVault ML6000 Maintenance Guide 9
If any of the tests fail, try the following resolutions and run the test again to make sure it passes:
•
Ping Test Failure
— Verify that the key server host is running and accessible from the network to
which the library is connected.
•
Drive Test Failure
— Look for any tape drive RAS tickets and follow the resolution instructions in the
ticket.
• Path Test Failure —server is actually running and that the port/SSL settings match the library
configuration settings.
• Config Test Failure —
• Verify that the key server is set up to accept the tape drive you are testing.
Differences Between Manual and Automatic EKM Path Diagnostics
There are two ways to perform EKM Path Diagnostics:
• Using Manual EKM Path Diagnostics
• Using Automatic EKM Path Diagnostics
• The Manual diagnostics differs from the Automatic diagnostics in the following ways:
The Manual diagnostics differs from the Automatic diagnostics in the following ways:
• The Manual diagnostics takes affected partitions offline.
• The Automatic diagnostics does not take partitions offline, but it may delay moves to tape drives
while they are being tested.
• The Manual 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). In addition, 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 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), 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, 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, use the Manual EKM Path Diagnostics. In particular, if you replace a
tape drive, run the Manual EKM Path Diagnostics.
Using Manual EKM Path Diagnostics
1 You can access the EKM Path Diagnostics screen in one of two ways:
• Service users can log on to the Web clientWeb client using the Service logon ID and password
and then select
Tools > Diagnostics
. Admin users must enter the Diagnostics menu and then
select
EKM > EKM Path Diagnostics
.
