Troubleshooting and Maintenance Manual

•
Firmware operation and port activity indicate that the link is down.
LEDs are visible through
openings in the adapter’s mounting bracket and indicate the conditions and results of the POST
function. A link-down is indicated when the green LED flashes and the yellow LED is off (see
Table 1 on page 21).
•
If the adapter has a power LED, the power LED indicates that power is off.
Some adapter
models have a separate green 3.3V power indicator LED (see page 19).
•
Topology and link speed are improperly matched for the adapter and the devices
connected to it.
If there is a mismatch, the link does not come up. If you make changes to the
topology or link speed parameters, you may need to reboot the system.
•
The boot code is improperly loaded, enabled or configured.
If boot code is enabled, the link
is reset any time the driver is loaded. If the boot code is not enabled, the link does not come up.
If boot code brings the link up, the link goes down when the adapter is reset.
•
Link status is other than operational.
Use the OneCommand Manager or HBAnyware
application to determine the link state.
•
OneCommand Manager
•
For an FC adapter, on the Port Information tab.
•
For iSCSI initiator, on the iSCSI Port Info tab.
•
For a NIC-only port, on the NIC Port Info tab.
•
For the HBAnyware application, click on the
General
tab and look at the Link Status
field. If the status is other than operational, the link is down.
•
The cable is not working.
Use a cable from a known working connection to test. Isolate the
problem to the adapter, cable or connected device.
•
If you have a loopback connector, the adapter fails the external loopback tests.
If you have
isolated the problem to the adapter, run an external loopback tests using the OneCommand
Manager or HBAnyware application or the Offline Utility.
•
The adapter optics do not match the cabling.
If the adapter is one type (single mode or
multimode) and your cabling is the other type, the link will not come up.
Cannot See Devices or Drives
Possible reasons why you cannot see devices or drives:
•
Some devices are not powered on
. Some adapter have a separate green 3.3V power indicator
LED (see page 19).
•
The LEDs indicate that the link is down
. On an adapter, a link-down is indicated when the
green LED flashes and the yellow LED is off (see Table 1 on page 21). On a switch, the LED
states vary depending on the switch vendor. See the switch vendor’s documentation.
•
The cable is not working.
Use a cable from a known working connection to test. Isolate the
problem to the adapter, cable or connected device.
•
The driver is improperly installed or loaded.
Verify that a compatible driver is completely
installed and loaded. Some devices may require a specific device driver installed on the host.
•
Automap is turned off.
The first time the machine boots with automap off, the devices are not
mapped to the OS. See the OneCommand Manager or HBAnyware application documentation
for more information where applicable.
•
On the FC Port driver, automap is off by default. Enable it using the OneCommand Manager
or HBAnyware application.
•
On the Storport Miniport and SCSIport Miniport drivers, automap is on by default. Change it
with the OneCommand Manager or HBAnyware application (SCSIport Miniport).
