Running the System Diagnostics

Since the system is directly attached to the channel of the host system, the communications
between the host system and all of the ESCON channel adapters must be stopped before
diagnostics are run on any ESCON channel adapter. See "Stopping Communications" for
this adapter for general guidelines, or see the AIX Version 4.1 Enterprise Systems
Connection Adapter: User's Guide and Service Information for detailed procedures.
Before disconnecting any cables from the adapter, the host system ESCON channel must
be stopped. Get the host system operator to do this for you.
The system diagnostics allow wrap testing at the adapter connector. See the AIX Version
4.1 Enterprise Systems Connection Adapter: User's Guide and Service Information for
detailed procedures.
