OneConnect and LightPulse LP21000 Adapters
OneConnect and LP21000 Checklist
Check CEE Switch Configuration.
Typical CEE environments will install two Converged Ethernet
Adapters in the hosts. Verify that the 10 Gigabit link is operational at the host and at the 10 Gigabit port
on the DCE switch. Check FCoE parameters on the DCE switch and ensure no changes were made to
the original settings. The OneCommand Manager or HBAnyware utilities (4.0 or later) allows you to
check CEE configuration parameters on a CNA such as firmware revision, pause type, FCoE priority,
and so forth.
Check Switch Zoning.
If you can see the LP21000 WWNN in the FC switch name server, it can be
zoned to storage. All zoning at this point is similar and can be managed the same as an adapter. Verify
driver, firmware, and boot versions from your storage and system provider.
OneConnect and LP21000 Symptoms
Symptoms such as POST failures and PCI problems for the LP21000 are usually similar to Emulex
adapters. Exceptions are problems that occur with incompatible Convergence Enhanced Ethernet
(CEE)/bridge and firmware for the LP21000 family. Ensure the correct firmware versions are installed.
Also ensure that you have the correct firmware version installed for the Media Access Control MAC
device.
•
10 G\bs Link down.
Unlike FC adapters, the Converged Network Adapter (CNA) is connected
to a lossless Ethernet fabric via 10 gigabit Enhanced Ethernet. The CNA has an additional green
LED for the 10 GbE link and indicates proper connection to the Data Center Ethernet switch. For
normal operation, this LED will blink. When this LED is off, a problem exists between the CNA
and FCoE switch.
•
FC Link Down.
If the 10 GbE connection to the FCoE switch is lost or the DCE switch is not
properly configured, both 10 GbE and the green FC LED will blink. The yellow LED will be off.
•
Can’t See Devices or Drives
. If you determine that the 10 GbE link is operational, check all FC
connections including ISL links between the FCoE switch and the FC switch and between the
FC switch and the storage array. If storage devices are missing, the CNA FC green LED may not
indicate this condition and the 10 GbE LED may continue to show a good link between CNA and
FCoE switch. Check zoning on the FC switch. Verify that the Data Center Ethernet is properly
set up for FCoE traffic.
Note:
For LP21000 adapters only. The LP21000 features an Intel 10 G\bs MAC
device. Ensure that the correct driver version is loaded for the device. You
must load the Intel driver separately from the other software drivers and
packages. See the Intel Web site for Intel drivers.
