General Information about Multiple Systems

If your system is attached to another system, certain actions performed by an operator can
affect either one or both systems, and these actions may require further consideration
before any changes are made to either system. Some actions requiring further consideration
are as follows:
Starting and stopping the communications with the other systems
Running diagnostics on one of the systems
Analyzing the error log information
Installing adapters or devices on any of the systems
Using the wrap plugs with the diagnostics
When this system unit is attached to another system, make sure you isolate this system unit
before stopping the operating system or running diagnostic programs. Some system cable
changes (such as installing wrap plugs or removing a device from the configuration) may
require the operator to perform an action on the attached system before making the cable
changes on this system.
