How to find World Wide Name (WWN) for a fibre channel HBA on Windows Server

How to find World Wide Name (WWN) for a fibre channel HBA

You can uses one of the following ways to view WWNs:

* HBAnyware utility (Emulex HBA only)

* SANsurfer utility (Qlogic HBA only)

* SAN switch’s name server output

If none of the above mentioned tools are accessible you can try Fibre Channel Information Tool utility FCINFO.EXE available for download from Microsoft Download web site. It works on Microsoft Windows Server 2003 and Microsoft Windows 2000 systems and comes in a form of MSI package for x86, IA64 or x64 platforms. However, as stated in the Release Notes the Fibre Channel Information Tool does not have to be installed to work correctly. Three core files must be copied in a common folder if the Fibre Channel Information Tool is not installed using the MSI installer: FCINFO.EXE, HBAAPI.DLL, HBATAPI.DLL.

Fibre Channel Information Tool utility is also included in the Microsoft Product Support Reporting Tool and other vendors' reporting tools, such as EMC Grab Utilities (EMCReports), Hewlett Packard Services Reporting Tool (HPS Reports), etc. If you ever run one of those tools on your server, you would have FCINFO.EXE installed.

Running the Fibre Channel Information Tool at a command line with no arguments will give basic information (including WWN) about the installed host bus adapters (HBAs):

C:\>fcinfo

There are 2 adapters:

com.qlogic-QLA2300/2310-0: PortWWN: 21:00:00:e0:8b:08:95:df \\.\Scsi2:

com.emulex-LP9002-1: PortWWN: 10:00:00:00:c9:30:d0:17 \\.\Scsi3:

If you type FCINFO /? or FCINFO /?? you will get a long list of commands, many of which are very task specific and not necessary for information gathering.

Management Lesson 101

Setting Up NIC Speed, Duplex setting on RHEL

There's a tool call ethtool on Red Hat / Centos / Fedora

First install this tool

# up2date ethtool net-tools

Task: Get speed and other information for eth0

Type following command as root user:

# ethtool eth0

Output:

Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: MII
PHYAD: 32
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: pumbg
Wake-on: d
Current message level: 0x00000007 (7)
Link detected: yes

Setup eth0 negotiated speed with ethtool

# ethtool -s eth0 speed 100 duplex full
# ethtool -s eth0 speed 10 duplex half

However, these settings are not permanent, if you reboot the system it will gone. To set it permanently, here is what you need to do:

To set the interface speed, duplex or auto negotiation on Linux system boot up (make settings permanent), you need edit /etc/sysconfig/network-scripts/ifcfg-eth0 file for eth0 interface. This file used by Red Hat enterprise Linux, Fedora core, Cent Os etc.

Open the file:

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

Append following line:

ETHTOOL_OPTS="speed 100 duplex full autoneg off"

Save and close the system. It will set the eth0 device to 100Mbs, full duplex, with the auto negotiation off at boot time. You can simply restart the networking (it will disconnect all ssh or ftp session) or restart the server. Depend upon traffic and load it may take upto 1 minute to setup a new port speed:

# /etc/init.d/network restart

If you want 1000Mbs set line as follows:

ETHTOOL_OPTS="speed 1000 duplex full autoneg off"

Update: if above command failed to work for 1000Mbps use following command (see below in comment sections for discussion) :

ETHTOOL_OPTS="speed 1000 duplex full autoneg on"

CRONTAB 101

This Applies to all managers

"The problem is the manager. He has a one-track relationship with players. Ask anyone here at Real Madrid. He can't change. You cannot go around just shouting at players. They need to feel special." -Jose Maurinho on Fabio Capello

Jose Maurinho is the special one, he is  the best manager.  He was not a good football player even he was dropped out of the squad, but he determine to be the best coach and now the only manager with PhD.
