Emulex Utilities for administration and configuration

I've started rolling scripts around most of the administrative tasks here, mainly so I'm not always the guy who has to pull the trigger on things. It also helps with consistency and makes integrating the changes into an automated build easier.

Here's a set of scripts I recently created to help me with managing and updating my Emulex HBA's with ESX 3.0.2. Specifically I use the HP Emulex LPe1105 (403621-B21) with BL460c blades.

First, get the bits from Emulex & HP. I use 2 components:

1. Lpfc Utility tarball:
   http://www-dl.emulex.com/support/vmware/lputil/20a14/lpfcutil-7.3.2-3.tgz
2. Model specific firmware (2.72 Nov. 07) :
   ftp://ftp.hp.com/pub/softlib/software9/COL11981/co-55809-1/fw_lpe11002_lpe1105_zf272a2.all

I'm still a little old school with my systems and I have a NFS mount made in the COS. It's a little more complicated and unsupported, but it works great. You can put the files anywhere that's accessibile to all systems or just copy them locally using scp or sftp.

Installation script (installEmulex.sh):

#!/bin/sh
SOURCE=#your source dir here
TARGET=/tmp/emulex
LFCUTIL=lpfcutil-7.3.2-3.tgz
LPBIN=/usr/sbin/lpfc

if [ -d $SOURCE ] ; then    
    if [ ! -d $TARGET ] ; then
         mkdir -p $TARGET
    fi
    cd $TARGET
    cp $SOURCE/$LFCUTIL $TARGET
 
    if [ -f $LFCUTIL ] ; then
        tar xvzf $LFCUTIL
        ./Install.sh
        cp Remove.sh $LPBIN
        cp README $LPBIN
            else
        echo "$LFCUTIL not found"
        exit 1
    fi
else     echo "Source directory $SOURCE cannot be accessed"
    rm -rf $TARGET
    exit 1
fi

I also like to make sure the topology is set to only allow point-to-point mode. Here's the code to do that globally on the system for all cards using the lpfcdd_732 driver.

setting emulex topology (setEmulexTopology.sh)

#!/bin/sh
esxcfg-module -s "lpfc_topology=0x2" lpfcdd_732esxcfg-boot -b

Here's how I update the firmware versions on the dual-channel HBA

update firmware (updateEmulexFW.sh)

#!/bin/sh
SOURCE=#your source dir here
LPUTIL=lputil
LPBIN=/usr/sbin/lpfc
ELFW=fw_lpe11002_lpe1105_zf272a2.all

if [ -d $SOURCE ] ; then
    cp -f $SOURCE/$ELFW $LPBIN
    if [ -f $LPBIN/$ELFW ] && [ -f $LPBIN/$LPUTIL ] ; then
       $LPBIN/$LPUTIL download 0 $LPBIN/$ELFW
       $LPBIN/$LPUTIL download 1 $LPBIN/$ELFW
     else
        echo "$LPUTIL or $ELFW not found"
        exit 1
    fi
else
     echo "Source directory $SOURCE cannot be accessed"
    exit 1
fi

finally let's drop these into a script that runs everything:

Emulex util installs (installEmulexUtils.sh)

#!/bin/sh
EXSOURCE=#dir where these live
$EXSOURCE/setEmulexTopology.sh
$EXSOURCE/installEmulex.sh
$EXSOURCE/updateEmulexFW.sh
echo "Reboot system for changes to take effect"

Labels: storage; fiber channel; emulex
