7133 Service Guide
Go to "MAP 2010: 7133 – START."
1. Run diagnostics, in System Verification mode, to the device that reported
the problem.
Note: Do not run Advanced Diagnostics; otherwise, errors are logged on
other using systems that share the same loop.
If the original problem was not reported by a device, run diagnostics to
each SSA adapter in the using system.
2. Run the Product Topology service aid (a non-SSA system service aid).
Note: If you do not run this service aid, the diagnostics might create an
SRN for a problem that has already been solved.
