TR3271 Management Programming Manual

TR3271 EVENT MANAGEMENT
4: ZTR3-EVT-CIU-ERR
Volatile Tokens
ZEMS-TKN-CU is a standard EMS token that contains the controller
and unit number. This token is present in the event buffer only
if the controller uses subchannel-type I/O addressing.
Event-Message Text
In the text message, ldev corresponds to the value of ZEMS-TKN-
LDEV, n,n,%nn,%nnn corresponds to the value of ZEMS-MAP-EXIOADDR,
ldevname corresponds to the value of ZEMS-TKN-LDEVNAME, and ciu-
status corresponds to the value ZTR3-TKN-CIU-STATUS.
Probable Cause
An error occurred on the indicated line. The I/O process
attempts a retry. If the problem persists, another path or
processor is tried. If another path or processor is not
available, the system brings down the line.
The value ciu-status in the text message indicates CIU-status
information. For a TR3271 communications line, this information
is the status word returned by the controller, in the format
described below.
