zx25d 408 The zcntl() control write (type <#>) to the X.25 link ZLU <#>
has unexpectedly failed with error <#>.
Explanation: The primary mechanism used by the X.25 Protocol
driver to establish the X.25 packet layer and for
managing VC Call Request, Clears, and Resets is
through special Control Write requests issued to the
X.25 firmware. A control write request is performed
using the zcntl() routine. One of these request has
unexpectedly failed. This may be a normal condition,
for example, in the case where the link is disconnected
right as a call is being placed. The type value indicates
the type of control write request issued and is
displayed for internal support purposes.
Action: Check the error returned against those listed in this
guide and take corrective action as necessary. If the
problem persists and you are unable to determine its
cause or the error code indicates a probable internal
defect, contact your HP support representative.
zx25d 409 The zread on ZLU <#> has unexpectedly failed with
error <#>.
Explanation: The X.25 protocol’s event handler routine was entered
to indicate that status message or protocol packet has
arrived. However, when the driver issued a zread call
to retrieve the event, the routine unexpectedly failed.
The zread request will be retried. If three consecutive
zread calls fail, the X.25 subsystem is disabled by the
driver.
Action: Check the error returned against those listed in this
guide and take corrective action as necessary. If the
problem persists and you are unable to determine its
cause or the error code indicates a probable internal
defect, contact your HP support representative.
