OneCommand Manager and HBAnyware applications port statistics
. All FC ports contain
link quality data (Link Error Status Block). This structure counts events such as link transitions,
CRC errors received, invalid transmission words received and other statistics. These counters
can detect bad cables or ports or misbehaving devices. The OneCommand Manager and
HBAnyware applications can display these counters for selected Emulex adapter ports.
•
Version Checking
.
Ensure that all versions of Emulex adapters, firmware, drivers, and software
are correct. This is critical to ensuring a stable SAN. The OneCommand Manager and
HBAnyware applications can collect and display this data all in one place.
•
Diagnostic Dump
. If necessary, use the OneCommand Manager and HBAnyware application to
keep a record of all the attributes of a server's adapter installation The Diagnostic Dump feature
collects attributes such as adapter models, firmware, driver, and software versions, driver
configuration parameters and stores it in a standard text file. The dump stops the selected
adapter port and dumps the adapter memory to a file for analysis by Emulex. This is not often
required, but can be useful when it is needed. Emulex Technical Support can advise when the
adapter memory dump file is required.
•
Diagnostic tests
.
Use the OneCommand Manager or HBAnyware utilities to test the adapter
port hardware and firmware. These tests are similar to the tests used in Emulex manufacturing
and can help identify malfunctioning adapter hardware.
Other Ways to Collect Data
Other SAN component manufactures provide tools to collect additional data. For example most fabric
switches provide ways to dump the port and switch configurations which can provide the switch firmware
revision, detailed information about zones, the display the port error counters for each switch port.
Common Problems
Hardware Issues
Symptoms that indicate you may need to return the adapter to Emulex for repair:
•
Host system (server) does not pass power-on self test (POST).
•
The server does not boot.
•
LEDs on the adapter stop flashing or flash an error code.
•
The bus has incorrect power.
•
Hardware errors are logged in the event log or message file.
•
There are onboard parity errors.
•
There are Peripheral Component Interconnect (PCI) parity errors.
•
There are firmware “traps”.
•
A physical FC interface problem looks similar to a bad cable but follows the adapter.
•
A high error count is reported for FC adapters on the Statistics tab of the OneCommand
Manager or on the Statistics tab of the HBAnyware application.
See page 16 for information on returning your adapter for repair.
