Connections between adjacent SAS ports is no longer a requirement for
systems running Data ONTAP 8.2; however, only the internal loopback test
will be run for systems with unconnected SAS ports.
6.2.5. FC-AL requirements
•
When running the FC-AL system-level diagnostic tests, you must have loopback hoods on FC-
AL interfaces on the motherboard or expansion adapters for best performance; all other cables
for storage or Fibre Channel networks must be disconnected from the ports.
While the use of loopback hoods on FC-AL interfaces are no longer
requirements for systems running Data ONTAP 8.2, the scope of the test
coverage on the interface is also reduced.
6.2.6. CNA requirements
•
The use of loopback hoods is not a requirement for running CNA system-level diagnostics
tests.
6.2.7. Interconnect requirements
•
Both platform controller modules in a dual controller system must be in Maintenance mode for
the interconnect system-level diagnostic test to run.
You will receive a warning message if you attempt to run the interconnect
system-level diagnostic test with other system-level diagnostic tests.
6.3. How to use online command-line help
You can get command-line syntax help from the command line by entering the
name of the command followed by help or the question mark (?).
The fonts or symbols used in syntax help are as follows:
•
keyword
Specifies the name of a command or an option that must be entered as shown.
•
< > (less than, greater than symbols)
Specify that you must replace the variable identified inside the symbols with a value.
•
| (pipe)
Indicates that you must choose one of the elements on either side of the pipe.
