SLES 11 FCoE Installation

## SLES 11 FCoE Installation

### Select FCoE During OS Installation

1. In Installation Settings, select FCoE Package
2. Click Details to enter a new window. Select additional installation package
3. Enter Search tab
4. In Search box, type "fcoe" and click "Search"
5. Select Open-fcoe package and click Accept
6. Click OK for questions to get back to "Installation Settings"

### Using Yast

| NOTE: If FCoE is installed during OS installation, then this is not required.

1. Select Software in the left pane
2. Select Software Management in the right pane
3. Type "fcoe" in the search box, then click Search button
4. "open-fcoe" package will show in right pane
5. Select "open-fcoe" package, then click Accept
6. Verify "Automatic Changes" and click OK

1. Click Install to install OS

### Install FCoE Package

#### Setting up Network Interfaces

After SLES 11 SP1 is operational, perform the following:

1. Ensure proper enumeration of network interfaces by editing

   /etc/udev/rules.d/70-persistent-net.rules
   (search for "SLES 11 udev rules" for relevant documentation, if needed)

> Changes in this file will not take effect until you reboot your system or shutdown all network interfaces and run a udevadm trigger

2. Verify proper configuration with

> ifconfig -a

#### Configuring LLDPad

#### Run commands:

> service lldpad start
> chkconfig lldpad on

Adjust DCB settings on the physical interface to be used for FCoE with these commands:

> dcbtool sc ethx dcb on
> dcbtool sc ethx app:0 e:1
> dcbtool sc ethx pfc e:1 a:1 w:1

#### Configuring FCoE

Create a configuration file for the VLAN interface. To copy cfg file, run command:

> > cp /etc/fcoe/cfg-ethx /etc/fcoe/cfg-eth1

Run commands:

> service fcoe start
> chkconfig fcoe on

FCoE is now installed and ready to use.

1. Check that vlan interface can obtain FC-ID. Run command

> > fcoeadm -i

#### Basic commands

| NOTE: "XYZ" is the VLAN ID used in your FCoE switch. The following example uses VLAN 101.

> create fcoe interface: fcoeadm -c ethx.XYZ-fcoe
> delete fcoe interface: fcoeadm -d ethx.XYZ-fcoe
> show interface info: fcoeadm -i
> show targets: fcoeadm -t
> show LUNs: fcoeadm -l
> show help: fcoeadm -h

### Manually Create VLAN

#### Create ifcfg-vlanXYZ script in /etc/sysconfig/network

| NOTE: Manually configuring a VLAN is no longer necessary, but the FCoE interface must be "up" so that fcoemon can discover the VLAN on which to pass FCoE traffic. The user can bring the interface "up" manually with ifconfig eth1 up or set the system to bring the interface up during boot by configuring a static address or DHCP.

The following example uses Yast for creating the vlan:

1. Open YaST and enter Network Devices in the left pane and Network Settings in the right pane
2. Configure the base adapter on the interface where you intend to set-up your VLAN. Set an IP address or configure the interface for DHCP.
3. Click "Add", under "Device Type," and select VLAN
4. Under Configuration Name, enter Vlan name, e.g., 0eth1.101 (101 is VLAN ID). This will create the vlan interface named "vlan0eth1.101"
5. In next window, under Real Interface for VLAN, ensure that you select the CORRECT interface
6. You can follow the defaults to completion

A new config file will be generated in /etc/sysconfig/network/. The file name is ifcfg-vlan0eth1.101 in above example.

> NOTE: The fipvlan tool (included in the open-fcoe rpm package) can determine what VLANs are visible.

> > eg.,

> > # fipvlan -a
> > Fibre Channel Forwarders Discovered
> > interface | VLAN | FCF MAC
> > ------------------------------------
> > eth1 | 101 | 00:0d:ec:a3:39:00
> > Indicates that VLAN 101 is visible on interface eth1. This interface is connected to a Fiber Channel Forwarder whose MAC address is 00:0d:ec:a3:39:00.

> > Use fipvlan --help for more details.
