7. Press F10 to save the changes and exit the BIOS Setup.
NOTE
Action: Refer to Hewlett Packard (HP) Customer Advisory Document c01199684 on the HP technical
support website for detailed information.
Adapter <port id>: BIOS not installed displays during boot process
An “Adapter <port id>: BIOS not installed” message displays when booting from an adapter.
Possible Cause: Either the boot image is not present in the adapter option ROM or initialization of
the adapter failed for some reason.
Action: Bring up the host system either using the Brocade live CD or boot from local disk. Download
the latest boot image (bfa_boot_fw) from the HBA website at www.brocade.com/hba. Enter the BCU
boot upload [adapter_id] <imange file> -a command to flash the option ROM on all installed
adapters with the same boot image.
Ethernet network interface problems (CNA only)
Use the following information to isolate problems that are more specific to CNA function.
NOTE
Switch command examples used in this section are for the Brocade 8000 Switch.
Ethernet link ports or LOM not coming up on reboot in Linux
The host system’s LAN on motherboard (LOM) is not coming up or CNA ports are not visible after
rebooting Linux host.
1. Possible Cause: A ifcfg-ethX script is not configured to bring up each LOM and CNA during the
system boot process.
Action: Make sure that a script is configured for each CNA and LOM once drivers are installed.
Scripts are located in the following directories:
• SLES - /etc/sysconfig/network
• RHEL - /etc/sysconfig/network-scripts
2. Possible Cause: NetworkManager is enabled. There are known issues with NetworkManager
managing multiple NICs in some Linux distributions.
Action: Disable NetworkManager.
To check if NetworkManager is running enter either of the following commands:
• chkconfig --list | grep NetworkManager
• nm-tool
To disable NetworkManager for RHEL 5 systems, enter the following commands:
chkconfig NetworkManager off
chkconfig NetworkManagerDispatcher off
