## Upgrading from Release 15.4

Instructions for upgrading a Windows FCoE-booted system can be found here.

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.

## Automatic Installation/Uninstallation/Disabling/Upgrading

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.

Note: | FCoE is supported on 82599-based Intel® Network Connections.

### Upgrading or Uninstalling Driver Will Cause Blue Screen

| Warning: Upgrading or uninstalling driver will cause blue screen Upgrading or uninstalling the network adapter driver via Windows Device Manager on the boot port will result in a lost connection to the SAN. The lost connection will result in a Windows blue screen on the next boot and will require the OS to be reinstalled.

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

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

- Configure FCoE initiator specific settings
- Ability to 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

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® 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.

### Miniport Device's Property Window Tabs

#### Fabric View Tab

The Fabric View Tab displays information about Targets and LUNs connected to the host adapter. It also displays detailed information about the host, the target and LUNs, e.g., the host name, target name, LUN capacity, FCID, etc.

NodeWWN | NodeWWN is a unique, 8-byte address of the node within the Fibre Channel network or domain.
PortWWN | PortWWN is an unique 8-byte address of the port within the Fibre Channel network or domain.
FcId | FcId is a 3-byte unique identifier that address a port within the fabric domain, usually assigned by the fabric.
Link Status | Connected Degraded (Class of Service not negotiated) Degraded (App mode disabled locally) Degraded (App mode disabled on peer) Connected (Class of Service unknown) Degraded (Data Center Bridging is disabled) Degraded (Data Center Bridging service not installed or started) Degraded (No Class Of Service negotiated) Degraded (PFC and APP setting mismatch) Degraded (Priority Flow Control is disabled) Degraded (Priority Flow Control not negotiated) Connected (Priority Flow Control state unknown) Not Connected (Fibre Channel link down) Not Connected
Refresh button | Scans for any new targets/LUNs added since the Fabric View property sheet was opened.

#### Advanced Tab

The Advanced Tab displays information about all the settings configurable from the host. These include Timeout Value, Linkdown Timeout, DeviceQDepth.

Port Properties | This button opens Intel® Proset for Windows* Device Manager for the selected adapter.
Settings: |
Timeout Value | Time in units of seconds before an SRB request initiated by the disk class driver will time out. For FCoE, valid values should range from 1 to 255 seconds.
Note: | A restart is required to implement Timeout Value setting changes.
DeviceQDepth | Changes the Drive I/O Queue Depth value. This change may affect driver performance. Values for this setting are between 1-252 in increments of 1. Default value: 32.
Linkdown Timeout | Changes the time limit that I/O will be held on a link down. This value supersedes the Timeout Value setting. The values are 2, 5, 10, 15, 20, 30, 60, 90, and 120. Default value: 20

#### Statistics Tab

The Statistics Tab displays information about FCoE statistics and errors since the initialization of the FCoE stack.

#### VLAN Tab

VLAN IDs are obtained through FIP VLAN discovery. This is a read-only page.

Status Options | "In Use" and "Not In Use"

### Boot Options Tab

Properties | Click on Properties button with Boot Targets selected to launch Target Properties Dialog.
Note: | This button displays if you have either iSCSI or FCoE boot enabled and a target selected in the Settings list.
Update Flash | 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® iSCSI Remote Boot, Intel® Boot Agent (IBA), Intel® 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.
Note: | You cannot update the flash image of a LOM; this button will be disabled.
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. 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.

## Jumbo Frames

The base driver supports FCoE mini-Jumbo Frames (2.5k bytes) independent of the LAN Jumbo Frames setting.
