TROUBLESHOOTING
A.1 OVERVIEW
The installation of the MD21/S2 Controller, when used with the
recommended devices, should run smoothly and problem-free. The
diagnostic procedures described in this manual are intended to help
you identify and resolve any problems you may encounter. However,
because of the wide variety of host adapters, disk drives and other
devices to which the MD21/S2 could be connected, diagnostic
procedures cannot be specific or all-inclusive. The following
subsections explain how to obtain technical assistance or service
for problems you cannot resolve.
A.2 PROBLEM IDENTIFICATION
The self-test, described in Section Six, diagnoses problems within
the MD21/S2 itself.
It does not diagnose problems with the host
adapter, disk drive, or other devices to which the MD21/S2 is
connected.
If the MD21/S2 does not pass the self-test when it is connected to
the other devices in your system, remove the devices and try the
self-test again. If the controller passes the self-test, the
problem may be elsewhere in the system. See directions for
obtaining help from Emulex's technical support personnel in the
subsection on Technical Assistance.
If the controller does not pass the self-test when it is tested
apart from the devices, it may be defective and should be returned
to the factory for replacement. See directions for returning the
unit in the subsection on Service.
A.3 TECHNICAL ASSISTANCE
If the MD21/S2 controller passed the self-test, but you believe it
is not performing as expected, you can obtain assistance from
Emulex's technical support personnel. The SCSI Product Performance
Report (see last two pages of Appendix A) allows you to gather all
the required information. Complete the form and mail it to Emulex
at the address on the form. A technical support representative
will contact you within five days of receipt of the form.
Note that this form is required in order for you to receive
technical assistance regarding your MD21/S2 controller. Please do
not attempt to contact Technical Support by any other means.
(If
you have not heard from Emulex after five days, you may call in to
check the status of your report.)
It is suggested that you use a photocopy of this form, so that the
form will be available should you need to use it again.
