## Upgrading from Software Release 15.4

Upgrades for Software Release 16.2 or later are supported when Intel® Ethernet FCoE Boot is enabled or the Windows paging file is on an FCoE target. Upgrading an FCoE-booted system can only be done via the Intel® PROSet for Windows* Device Manager installer. A reboot is required to complete the upgrade.

| Warning: Do not update X520 base driver via the Windows Update method Doing so may render the system inoperable, generating a blue screen. The FCoE Stack and base driver need to be matched. The FCoE stack may get out of sync with X520, if the X520 base drive is updated via Windows Update.

The Windows FCoE stack has recently changed the way it creates the initiator WWPN. The first two bytes of the WWPN previously contained a 2 followed by the FCoE fabric VLAN ID. The VLAN ID is no longer added to the WWPN and the first two bytes will now always be 20:00. After upgrading from Release 15.4, you will need to zone the new WWPN for each initiator port.

## Validation and Storage Certification

The software components for Intel® Ethernet FCoE are comprised of two major components: the Intel® Ethernet base driver and the Intel® Ethernet FCoE Driver. They are developed and validated as an ordered pair. Users are strongly encouraged to avoid scenarios, either through upgrades or Windows update, where the Intel® Ethernet driver version is not the version released with the corresponding Intel® Ethernet FCoE driver. Listed below is a table with the released versions and the associated base driver and the Intel® Ethernet FCoE Driver.

Notes: | Individually upgrading/downgrading the Intel® Ethernet FCoE driver will not work and may even cause a blue screen; the entire FCoE package must be the same version. Upgrade the entire FCoE package using Intel® Network Connections only. If you uninstalled the Intel® Ethernet Virtual Storage Miniport Driver for FCoE component, just find the same version that you uninstalled and re-install it; or uninstall and then re-install the entire FCoE package.

Version | Qualified | NDIS Miniport Driver | Intel® Ethernet FCoE Drivers
15.4 | No | 2.5.52.0 | 1.0.2.0
15.4.1 | Yes | 2.5.52.0 | 1.0.2.1
15.4.2 | Netapp | 2.5.52.0 | 1.2.6.0
15.4.3 | EMC | 2.5.52.0 | 1.2.8.0
15.8 | No | 2.6.121.0 | 1.3.23.0
16.0 | No | 2.7.28.0 | 1.4.6.0
16.2 | EMC, Netapp | 2.8.32.0 | 1.5.9.0
16.4 | No | 2.9.66.0 | 1.6.5.0

Intel and the storage vendors spend considerable effort ensuring that their respective products operate with each other as expected for every version that we release. However, given the sheer number of releases and each respective organizations' differing schedules, users are strongly encouraged to use their storage vendor's support matrix to ensure that the versions that they are deploying for the Intel® Ethernet Protocol Driver, the switch and storage vendor have been tested as an integrated set.

## New Windows* Server 2008 Installation

From the Intel CD: Click the FCoE/DCB checkbox to install Intel® Ethernet FCoE Protocol Driver and DCB. The MSI Installer installs all FCoE and DCB components including Base Driver.

Notes: | FCoE is supported on 82599 and X540-based Intel® Network Connections. We recommend installing using the latest Storage Qualified Image. For current drivers and documentation, visit the Customer Support site.

## Intel® Ethernet FCoE Configuration Using Intel® PROSet for Windows* Device Manager

Many FCoE functions can also be configured or revised using Intel PROSet for Windows Device Manager, accessed from the FCoE Properties button within the Data Center tab. You can use Intel PROSet to perform the following tasks:

- Configure FCoE initiator specific settings
- Go to the corresponding port driver
- Review FCoE initiator information
- Obtain general information
- Review statistics
- Obtain information about the initiator
- Obtain information about attached devices
- FIP discovered VLANs and status

Click here for instructions on installing and using Intel PROSet for Windows Device Manager.

Note: | PROSetCL.EXE is used for DCB/FCoE configuration on Microsoft* Windows* Server 2008 Core and Microsoft* Windows* Server 2008 R2 Core operating systems.

Notes: | From the Boot Options Tab, the user will see the Flash Information Button. Clicking on the Flash Information Button will open the Flash Information Dialog. From the Flash Information Dialog, clicking on the Update Flash button allows Intel® iSCSI Remote Boot, Intel® Boot Agent (IBA), Intel® Ethernet FCoE Boot, EFI, and CLP to be written. The update operation writes a new image to the adapter's Flash and modifies the EEPROM, which may temporarily disable the operation of the Windows* network device driver. You might need to reboot the computer following this operation. You cannot update the flash image of a LOM; this button will be disabled.

### Intel Ethernet Storage Miniport Driver for FCoE Properties Tabs

There are two ways to navigate to the FCoE properties. One using the X520 Network adapter properties Data Center tab and other through Intel® Ethernet Virtual Storage Miniport Driver for FCoE Storage Controllers properties from Windows Device Manager.

### Network Adapter Miniport Device’s Properties Tabs

#### Boot Options Tab

####

From the Boot Options tab you can obtain Target information and Update the Flash.

####

Enabling FCoE boot will allow user to boot from FCOE LUN.

####

Selecting Boot Target in the above Window will allow user to select FCoE LUNs and their respective boot order.

####

SETTINGS: |
Active Image | Enables/disables the boot options in the EEPROM. The update operation modifies the EEPROM to enable an option ROM, already contained within the flash. This may temporarily disable the operation of the Windows* network device driver. You might need to reboot the computer following this operation.
Boot Targets | The server side system in an FCoE SAN configuration. The FCoE Boot Target system hosts the FCoE target drives which are accessed by an FCoE Boot initiator.
Update Flash Button | Click on the Flash Information Button to open the Flash Information Dialog. From the Flash Information Dialog clicking on the Update Flash button allows Intel® Ethernet FCoE Boot, Intel® iSCSI Boot, Intel® Boot Agent (IBA), EFI, and CLP to be written. The update operation writes a new image to the adapter's Flash and modifies the EEPROM, which may temporarily disable the operation of the Windows* network device driver. You might need to reboot the computer following this operation.
Note: | You cannot update the flash image of a LOM; this button will be disabled.
Properties Button | Click on Properties button with Boot Targets selected to launch Target Properties Dialog.
Note: | This button displays if you have either Intel® Ethernet iSCSI or Intel® Ethernet FCoE Boot enabled and a target selected in the Settings list.
Target Properties Dialog |
Target: | Each Target field contains WWPN numbers for the FCoE boot targets discovered on the network, and the network, and None Selected.
LUN: | Each LUN field displays the LUNs on the selected target. If no target is selected, the LUN field is empty.
Boot Order: | Boot Order field options are 1, 2, 3, 4, and Not Set.
LUN and Boot Order fields are disabled and cleared when target is set to None Selected. Intel® Ethernet FCoE Boot cannot be enabled on an adapter that has a VLAN or is in a team. If the current adapter is in a team or has a VLAN, then all fields are disabled.

#### Data Center Tab

User must enable Use Data Center Bridging to be able to use Intel® Ethernet FCoE.

Changing FCoE priority allows the user to choose a different priority class for FCoE traffic on the converged Ethernet network. Adjusting Bandwidth percentage ensures FCoE traffic is allocated to specified minimum guaranteed bandwidth. All other traffic classes will share the remaining bandwidth. Bandwidth allocation rules are enforced when maximum available bandwidth is being utilized.

Use Switch Settings

Use local settings

From the Data Center tab you can, among other things: view operational status, select FCoE settings, and enable/disable Data Center Bridging (DCB).

- Display Status

(operational or non-operational) by clicking on theicon.

- Enhanced Transmission Selection
- Priority Flow Control
- FCoE Priority

Non operational status: If the Status indicator shows that DCB is non-operational, there may be a number of possible reasons.

1. DCB is not enabled - select the checkbox to enable DCB.
2. One or more of the DCB features is in a non-operational state. The features which contribute to the non-operational status are PFC and APP:FCoE.

A non-operational status is most likely to occur when Use Switch Settings is selected or Using Advanced Settings is active. This is generally a result of one or more of the DCB features not getting successfully exchanged with the switch. Possible problems include:

- One of the features is not supported by the switch.
- The switch is not advertising the feature.
- The switch or host has disabled the feature (this would be an advanced setting for the host).

When Use Local Settings is selected, the status should always be operational.

Note: | In most circumstances, we recommend selecting Use Switch Settings, rather than Use Local Settings.

Note: | Options on the Data Center tab are grayed out: You cannot disable DCB or modify any DCB settings while the system is booted from an FCoE drive or if the system paging file is on an FCoE drive.

- Disable/enable
- Configuring host to use the settings provided by the switch or to use local settings
- Troubleshooting information
