Chapter 5. Problem Determination
Hardware, microcode, or software failures may occur in a data network. These
errors are identified and notified to the host by the 3745. They are handled
differently depending on whether the host is equipped with:
The VTAM access method along with the NetView program, or
The VTAM access method only.
Two types of error are considered:
1. Controller errors (component of the 3745 itself)
These errors are detected by the MOSS, and can be fixed either by the
customer or by the IBM service organization (see pages 6-2 and 6-3).
|
2. Network errors (DCEs, lines, stations, token-rings, Ethernet-type LANs, and so
|
on).
These errors are detected by the NCP or PEP. The appropriate service
organization should be called (DCE or DTE maintainers, PTT, common carrier,
and so on).
Error Detection and Reporting
The 3745 is equipped with several error detectors implemented in the:
- Hardware
- Microcode
- NCP or PEP.
