Fallback Considerations
None.
Volume Level Encryption for Disks and Tapes
Volume level encryption for data at rest on tape and disks connected with Storage CLIMs is
supported on NonStop Integrity BladeSystems (J-series), NonStop Integrity NS16000 series
servers (H-series), and NonStop Integrity NS2000 series servers (H-series).
For more information, refer to the NonStop Storage Encryption Guide.
Migration Considerations
To use this feature, you must purchase a system license and an HP ESKM (Enterprise System
Key Manager) device.
Fallback Considerations
Before you fall back to a prior version of CLIM software, you should decrypt your data, otherwise
you will lose access to it.
$ZHOME Process Enhancements
The EMS message for event 512 for the $ZHOME process is now prefixed by the name and
CPU,PIN of the process that writes to $0 via $ZHOME. EMS event number 512 is identified as
WRITE-TO-0. The format for the EMS event 512 with this feature is as follows:
<Generation-time><ZHOME Process-ID><Subsystem-ID>
000512<cpu,pin><process-name>:<original-message>
The format for EMS event 512 without this feature is as follows:
<Generation-time><ZHOME Process-ID><Subsystem-ID>
000512<original-message>
Migration Considerations
• If your application parses $0 text, you might need to change the application to accommodate
the additional information related to process ids and process names for 512 events originating
from $ZHOME.
• EMS event 512 is written to $0 as a text message. This text message has a limit of 102 bytes.
Thereafter, it will be truncated if the total length of the message (including the process name
and (CPU,PIN) crosses 102 bytes.
Fallback Considerations
If you modified a program to handle the new format of the EMS event text and then fall back,
you’ll need to revert to the version of your program that understands the old format.
