The scanner scannernum in the IBM® 3725 or 3745 Communication Controller is unavailable because of a hardware error on a possible range of line numbers between line1 and line2. This message is always preceded by IST756E, which identifies the name of the communication controller. The RECFMS request received by VTAM® had the user action code of 12 in it. Additional information is provided in the Operating Guide for your communication controller.
All affected lines are inoperative.
Follow the predefined recovery or backup actions, or both, for your network. Transfer the dump of the communication-scanner processor to a data set in the host using the MODIFY DUMP command. This will allow another dump on the MOSS diskette. Save the system log for problem determination.
Reload the affected scanner. No other action is required unless the problem occurs repeatedly. If it does, contact the IBM hardware support center.
