Emulex Drivers for VMware ESXi for OneConnect Adapters Release Notes 2 DRVVM-OCA-RN1121 Resolved Issues 1. This version resolves an issue in which Emulex network adapter interfaces were configured in NIC Teaming mode, one of the interfaces went down, and a long failover time resulted in packet loss. This Component Package contains the iSCSI driver for the HPE Emulex 10/20Gb Server Adapters for Windows Server 2016.

Fibre Channel (FC) provides drivers for various FC Host Bus Adapters (HBAs). Fibre Channel is a gigabit-speed network technology primarily used for storage networking.

Overview

Fibre Channel is standardized in the T11 Technical Committee of the Inter National Committee for Information Technology Standards (INCITS), an American National Standards Institute (ANSI) - accredited standards committee.

Fibre Channel has been the standard connection type for storage area networks (SAN) in enterprise storage. Despite its name, Fibre Channel signaling can run on both twisted pair copper wire and fiber-optic cables.

The Fibre Channel Protocol (FCP) is a transport protocol which predominantly transports SCSI commands over Fibre Channel networks.

Hardware support

The following QLogic Fiber Channel HBAs are supported in 4/8-gigabit mode:

  • QLogic 2400 Series (QLx246x), 4GFC
  • QLogic 2500 Series (QLE256x), 8GFC (fully qual'd)

The QLogic Fibre Channel fabric module (qla2xxx.ko, Linux kernel driver database) for the Linux SCSITarget was released with Linux kernel 3.5 on July 21, 2012.[1]

With Linux 3.9, the following 16-gigabit QLogic Fibre Channel HBA is supported, which makes LIO the first open source target to support 16GFC:

  • QLogic 2600 Series (QLE266x), 16GFC, SR-IOV

With Linux 3.9, the following QLogic CNAs are also supported:

  • QLogic 8300 Series (QLE834x), 16GFS/10 GbE, PCIe Gen3 SR-IOV
  • QLogic 8100 Series (QLE81xx), 8GFC/10 GbE, PCIe Gen2

Enable target mode

By default, the upstream qla2xxx driver runs in initiator mode. To use it with LIO, first enable Fibre Channel target mode with the corresponding qlini_mode module parameter.[2]

To enable target mode, add the following parameter to the qla2xxx module configuration file:

Depending on your distribution, the module configuration file might be different, for instance:

  • /etc/modprobe.d/qla2xxx.conf: CentOS, Debian, Fedora, RHEL, Scientific Linux
  • /etc/modprobe.conf.local: openSUSE, SLES

In order for these changes to take effect, the initrd/initramfs will need to be rebuilt.

Please verify that initrd/initramfs is accepting the additional qla2xxx parameter.

targetcli

targetcli from Datera, Inc. is used to configure Fibre Channel targets. targetcli aggregates LIO service modules via a core library, and exports them through an API, to provide a unified single-node SAN configuration shell, independently of the underlying fabric(s).

Cheat sheet

Command Comment
/backstores/iblock create my_disk /dev/sdb Create the LUN my_disk on the block device /dev/sdb
/qla2xxx create <WWPN> Create a Fibre Channel target
In /qla2xxx/<WWPN>:
luns/ create /backstores/iblock/my_disk
Export the LUN my_disk
In /qla2xxx/<WWPN>:
acls/ create <Initiator WWPN>
Allow access for the initiator at <WWPN>
/saveconfig Commit the configuration

Startup

targetcli is invoked by running targetcli as root from the command prompt of the underlying LIO shell.

Upon targetcli initialization, the underlying RTSlib loads the installed fabric modules, and creates the corresponding ConfigFS mount points (at /sys/kernel/config/target/<fabric>), as specified by the associated spec files (located in /var/target/fabric/fabric.spec).

Display the object tree

Use ls to list the object hierarchy, which is initially empty:

Per default, auto_cd_after_create is set to true, which automatically enters an object context (or working directory) after its creation. The examples here are modeled after this behavior.

Emulex Oneconnect Driver

Optionally, set auto_cd_after_create=false to prevent targetcli from automatically entering new object contexts after their creation:

Create a backstore

Emulex

Create a backstore using the IBLOCK or FILEIO type devices.

For instance, enter the top-level backstore context and create an IBLOCK backstore from a /dev/sdb block device:

targetcli automatically creates a WWN serial ID for the backstore device and then changes the working context to it.

The resulting object hierarchy looks as follows (displayed from the root object):

Emulex SCSI & RAID Devices Driver

Alternatively, any LVM logical volume can be used as a backstore, please refer to the LIO Admin Manual on how to create them properly.

For instance, create an IBLOCK backstore on a logical volume (under /dev/<volume_group_name>/<logical_volume_name>):

Again, targetcli automatically creates a WWN serial ID for the backstore devices and then changes the working context to it.

Instantiate a target

The Fibre Channel ports that are available on the storage array are presented in the WWN context with the following WWNPs, for instance:

  • 21:00:00:24:ff:31:4c:48
  • 21:00:00:24:ff:31:4c:49

Instantiate a Fibre Channel target, in this example for QLogic HBAs, on the existing IBLOCK backstore device my_disk (as set up in targetcli):

targetcli automatically changes the working context to the resulting tagged Endpoint.

Export LUNs

Declare LUNs for the backstore device, to form a valid SAN storage object:

targetcli per default automatically assigns the default ID '0' to the LUN, and then changes the working context to the new SAN storage object. The target is now created, and exports /dev/sdb as LUN 0.

Return to the underlying Endpoint as the working context, as no attributes need to be set or modified for standard LUNs:

Define access rights

Configure the access rights to allow logins from initiators. This requires setting up individual access rights for each initiator, based on its WWPN.

Determine the WWPN for the respective Fibre Channel initiator. For instance, for Linux initiator systems, use:

For a simple setup, grant access to the initiator with the WWPN as determined above:

Emulex Lightpulse Hba Driver

targetcli per default automatically adds the appropriate mapped LUNs.

Display the object tree

The resulting Fibre Channel SAN object hierarchy looks as follows (displayed from the root object):

Persist the configuration

Use saveconfig from the root context to persist the target configuration across OS reboots:

Spec file

Datera spec files define the fabric-dependent feature set, capabilities and available target ports of the specific underlying fabric.

In particular, the QLogic spec file /var/target/fabric/qla2xxx.spec is included via RTSlib. WWN values are extracted via /sys/class/fc_host/host*/port_name in wwn_from_files_filter, and are presented in the targetcliWWN working context to register individual Fibre Channel port GUIDs.

Scripting with RTSlib

Setup script

The following Python code illustrates how to setup a basic Fibre Channel target and export a mappedLUN:

Note that while Fibre Channel TPGs are masked by targetcli, they are not masked by RTSlib.

Devices

The resulting object tree looks as follows:
