HP ProLiant DL980 G7 Maintenance And Service Manual page 65

NOTE: For ProLiant DL980 G7 servers, when there is an HP NC550SFP 10Gb 2-port PCIe
x8 Ethernet Adapter in I/O slot 9 and an HP CN1000E Converged Network Adapter in I/O
slot 10, during a network stress test (netperf), the connection in the second port of the CN1000E
may be dropped. This issue may also occur when there is an HP CN1000E Converged
Network Adapter in slot 9 and a HP CN1000E Converged Network Adapter in slot 10.
This issue occurs in the following scenario:
1. Run a network stress test (netperf).
2. Shut down the stress test and reboot the server.
3. Run netperf again.
4. The connections to the clients will be made at a slow rate and then finally the connection
to slot 9 and 10 will be dropped.
This occurs because the ServerEngines driver is not getting enough MSI messages at driver
load time. On a ProLiant DL980 system, the driver is not getting enough MSI-X interrupts, so
the system is reverting to legacy interrupt mode.For any ProLiant DL980 G7 server running
Windows Server 2008 that has either an NC550SFP in slot 9 and an HP CN1000E Converged
Network Adapter in slot 10 or an HP CN1000E Converged Network Adapter in slot 9 and
an HP CN1000E Converged Network Adapter in slot 10, perform the following to allow
netperf to run in this configuration without connections dropping:
1. Go to the Start menu, then "Run."
2. Type "cmd."
3. From the command prompt, type "bcdedit /set UsePhysicalDestination yes."
NOTE: When multiple LAN-On-Motherboard (LOM) ports on an NC375i Network Adapter
configured in a ProLiant DL980 G7 server are connected to a DHCP and a PXE server, booting
from the PXE server may not succeed with the following error message:
No filename or root path specified(There is no F12 key option available to boot from a PXE
server.)This occurs due to the PXE implementation in the adapter firmware, which is not
HP-specific.his issue only occurs when more than one LOM ports are connected AND Port 2
is used to boot from the PXE server. If only Port 2 is connected, the PXE boot will succeed.
NOTE: If an HP ProLiant DL980 G7 with System ROM 2010.07.27 or a ProLiant DL580
G7 with System ROM 2010.08.28 is used with Integrated Lights-Out 3 (iLO 3) Firmware
Version 1.15 (or later) and I/O cards are installed in SubIO (I/O expansion board) slots or
LPIO (Low Profile PCI-e I/O expansion board) slots, then the server Power-On-Boot process
may stop responding at the point where "Inlet Ambient Temperature" is displayed.
The issue has been detected with a large range of I/O cards including the HP NC522SFP
10G NIC, Smart Array P212 Controller, and Smart Array P800 Controller. In addition, this
may also potentially occur when any I/O card is installed in SubIO/LPIO slots with the
BIOS/iLO 3 firmware combination described above.When this occurs, there are no Integrated
Management Log (IML) events or other indications other than the boot sequence does not
progress past "Inlet Ambient Temperature" as shown above.To prevent the server from ceasing
to respond during the Power-On-Boot process, upgrade the System ROM to HP ProLiant DL980
G7 System ROM 201 1.01.27 (or later).
NOTE: Any HP ProLiant DL980 server configured with any of the following HP IO Accelerator
cards:
◦
160GB SLC PCIe ioDrive (part number 600278-B21)
◦
320GB MLC PCIe ioDrive (part number 600279-B21)
◦
320GB SLC PCIe ioDuo (part number 600281-B21)
◦
640GB MLC PCIe ioDuo (part number 600282-B21)
