User Complaints
User Complaints
Most troubleshooting starts with user complaints, which can result from either
application or hardware problems. The best approach is always to check the obvious
first. For example:
•
Were any error messages returned? If so, what are they?
•
Did the user use the correct command syntax when accessing resources through
the network?
•
Was the complaint subjective (for example, slow response)? Were the user’s
expectations reasonable?
SCF Commands
SCF can be used to display information about Expand line-handler processes and FOX
rings. This subsection describes the most useful SCF commands for troubleshooting.
LISTDEV Command
The SCF LISTDEV command can be used to verify that system processes are active.
