HP Fibre Channel Mass Storage Adapters Support Guide FibrChanl-03 (fcoc) Driver HP-UX 11i v3

Firmware Updates
This section explains the process for updating the firmware of your Fibre Channel host bus adapter.
Fibre Channel Host Bus Adapter Online Firmware Updates
Online firmware updates are not supported by this HBA.
Fibre Channel Host Bus Adapter Offline Driver and Firmware Updates
The HBA's firmware and EFI can be updated through the update utility run under the Device
Manager in EFI, via the networking port of the NC551m, NC553m and CN1100 cards.
Fibre Channel Device Scanning Policy Configuration for HP Integrity
Systems
Because fibre channel SANs can contain many potential boot devices, it is necessary to use an
appropriate EFI device scanning policy, when booting an HP Integrity server which is connected
to a SAN. The intent of the device scanning policy is to allow a fibre channel EFI driver to find a
fibre channel boot device, yet still allow the scanning process to complete in a reasonable amount
of time.
Most HP Integrity servers implement default device scanning policies that work well with fibre
channel without needing modification. For example, the server’s default policy might start a single
EFI driver, which is attached to a known boot path. If the system is booting from a SAS internal
disk, for example, the server would not start the fibre channel EFI driver. Another way that an HP
Integrity server can speed the boot process is to pass the known boot path directly to the EFI driver.
The EFI driver then only needs to search the SAN for that particular target and LUN.
In most cases, the server’s default EFI device scanning policy should not need modification to work
properly with host bus adapters supported by the fcoc HP-UX driver. In certain cases, it is useful
to expand the EFI driver’s device scanning policy:
• When you want to use the EFI shell to access an EFI disk partition attached to a host bus
adapter.
• When your system is experiencing boot failures and you want to ensure that the EFI driver is
scanning the device.
• When you are using an HP Integrity server that does not support a default scanning policy
suitable for discovering the boot device.
For adapters supported by the fcoc HP-UX driver, you change the EFI driver’s device scanning
policy using the FCOC Configuration Utility at the EFI level.
To be able to boot from SAN, the Set Boot from San parameter must be set to Enable.
