Troubleshooting: Broadcom NetXtreme II Network Adapter User Guide
Problem: Routing does not work for NetXtreme II 10 GbE network adapters installed in Linux systems.
Solution: For NetXtreme II 10 GbE network adapters installed in systems with Linux kernels older than 2.6.26, disable TPA
with either ethtool (if available) or with the driver parameter (see disable_tpa). Use ethtool to disable TPA (LRO) for a specific
NetXtreme II 10 GbE network adapter.
Problem: On a NetXtreme II 1 GbE network adapter in a CNIC environment, flow control does not work.
Solution: Flow control is working, but in a CNIC environment, it has the appearance that it is not. The network adapter is
capable of sending pause frames when the on-chip buffers are depleted, but the adapter also prevents the head-of-line
blocking of other receive queues. Since the head-of-line blocking causes the on-chip firmware to discard packets inside the
on-chip receive buffers, in the case a particular host queue is depleted, the on-chip receive buffers will rarely be depleted,
therefore, it may appear that flow control is not functioning.
Problem: A bnx2id error appears when installing SLES 10 SP3 SBUU build 36.
Solution: bnx2id is a user space component that needs to be compiled at the time the package is installed. See your OS
documentation for properly installing a compiler.
Problem: How do I disable bnx2id service on a system that does not have iSCSI enabled?
Solution: Type service bnx2id stop. Change the bnx2id runlevels to off using chkconfig or via the GUI.
Problem: How do I rebuild the bnx2id daemon after installing a compiler?
Solution: Change the directory to /usr/src/netxtreme2-version/current/driver and type make install_usr.
Problem: Errors appear when compiling driver source code.
Solution: Some installations of Linux distributions do not install the development tools by default. Ensure the development
tools for the Linux distribution you are using are installed before compiling driver source code.
Miscellaneous
Problem: When setting the Jumbo MTU property to 5000 bytes or greater and forcing Flow Control on network adapters
that support a link speed of 10 Gbps, the system performance performs at less than optimal levels.
Solution: If Jumbo MTU is set to 5000 bytes or greater, ensure that Flow Control is set to Auto.
Problem: iSCSI Crash Dump is not working.
Solution: After upgrading the device drivers using the installer, the iSCSI crash dump driver is also upgraded, and iSCSI
Crash Dump must be re-enabled from the Advanced section of the BACS Configuration tab.
Problem: In Windows 2008 R2, if the OS is running as an iSCSI boot OS, the VolMgr error, "The system could not
successfully load the crash dump driver," appears in the event log.
Solution: Enable iSCSI Crash Dump from the Advanced section of the BACS Configuration tab.
Problem: The Broadcom NetXtreme II adapter may not perform at optimal level on some systems if it is added after the
system has booted.
Solution: The system BIOS in some systems does not set the cache line size and the latency timer if the adapter is added
after the system has booted. Reboot the system after the adapter has been added.
Problem: Intelligent Platform Management Interface (IPMI) is not functioning properly.
Solution: IPMI works only when LiveLink™ is disabled. See
SLB (Auto-Fallback Disable)
Problem: Cannot configure Resource Reservations in BACS after SNP is uninstalled.
Solution: Reinstall SNP. Prior to uninstalling SNP from the system, ensure that NDIS is enabled via the checkbox on the
Resource Configuration screen, available from the Resource Reservations section of the Configurations tab (see
Configuring Resource Reservations). If NDIS is disabled and SNP is removed, there is no access to re-enable the device.
Problem: The TOE status in the Vital Sign area of the BACS Information tab is inconsistent with the TOE status in the
Resource Reservations tab when the TOE key is physically removed.
