EVENT MANAGEMENT
4: ZEXP-EVT-DEV-ERR
Probable Cause
An error occurred on the indicated line, and the I/O retry did
not succeed. The tokens ZEXP-TKN-DEV-STATUS and ZEXP-TKN-DEV-
STATUS-MASK supply information about the error. If the error
involves a controller ownership switch, the line handler retries
for up to three ownership switches; if the error persists, it
brings down the line. For any other error (for instance, a modem
error), the line handler waits for the error to clear, and then
retries.
Recommended Action
If the information in ZEXP-TKN-DEV-STATUS and ZEXP-TKN-DEV-
STATUS-MASK indicates a problem with Tandem hardware, contact
your Tandem representative.
