Recovery. Informational message only; no corrective action is needed.

reason
is text that describes the reason that the backup copy of the process has taken 
over its open terminal sessions.
Cause. The primary process was stopped by an operator action, terminated 
abnormally, or stopped because its processor stopped.
Effect. Loss or duplication of data can occur within some terminal sessions. 
Noninteractive users of the subsystem should be encouraged to check data from 
sessions open when the takeover occurred.
Recovery. Informational message only; no corrective action is needed. The backup 
copy of the process maintains the process’s open terminal sessions.

error-number
is the Guardian file-system error returned by the underlying Guardian procedure 
call.
Cause. The backup process cannot perform a checkpoint. See the Guardian 
Procedure Errors and Messages Manual for more information about error-number, 
or use the HP Tandem Advanced Control Language (TACL) ERROR command for an 
online explanation.
Effect. The backup process is no longer operational.
Recovery. Stop and restart OSSTTY. If the problem persists, contact your service 
provider and provide all relevant information as follows:
•
Descriptions of the problem and accompanying symptoms
•
Details from the generated message or messages
•
Supporting documentation such as Event Management Service (EMS) logs, trace 
files for both the primary and backup process, and a processor dump, if applicable
If your local operating procedures require contacting the Global Customer Support 
Center (GCSC), supply your system number and the numbers and versions of all 
related products as well.
