Adding a physical disk as RAID 0 using hpacucli in Debian GNU/Linux and HP DL380 G7

This webpage shows hpacucli in Linux.

To install hpacucli in Debian GNU/Linux you may add the HP's repository for the distro in /etc/apt/sources.list:

deb http://downloads.linux.hp.com/SDR/downloads/ProLiantSupportPack/ lucid current/non-free

Yes, I know it means Ubuntu, but it worked for me.

apt-get update
apt-get install hpacucli

Run hpacucli:

# hpacucli
HP Array Configuration Utility CLI 8.60-8.0
Detecting Controllers...Done.
Type "help" for a list of supported commands.
Type "exit" to close the console.


=>

The current situation:

=> ctrl all show config

Smart Array P410i in Slot 0 (Embedded)    (sn: 50014380102A5090)

   array A (SAS, Unused Space: 0 MB)


      logicaldrive 1 (558.9 GB, RAID 0, OK)

      physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 600 GB, OK)

   unassigned

      physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 600 GB, OK)
      physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 600 GB, OK)
      physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 600 GB, OK)
      physicaldrive 2I:1:5 (port 2I:box 1:bay 5, SAS, 600 GB, OK)
      physicaldrive 2I:1:6 (port 2I:box 1:bay 6, SAS, 600 GB, OK)

   SEP (Vendor ID PMCSIERA, Model  SRC 8x6G) 250 (WWID: 50014380102A509F)

=>

I need each disk installed individualy, not mixed in arrays.

To add one physical disk as RAID 0:

=> ctrl slot=0 create type=ld drives=1I:1:2 raid=0

Then, the result is what I expected:

=> ctrl all show config                           

Smart Array P410i in Slot 0 (Embedded)    (sn: 50014380102A5090)

   array A (SAS, Unused Space: 0 MB)

      physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 600 GB, OK)

   array B (SAS, Unused Space: 0 MB)


      logicaldrive 2 (558.9 GB, RAID 0, OK)

      physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 600 GB, OK)

   unassigned

After that, you may setup LVM in minutes as this site suggests.

Nice, what powerful the console is!

Installing Debian GNU/Linux 6 from network using a USB flash drive and HP firmware for HP DL380 G7

This is the easiest way to do the job (of course, it is not a new procedure but I need to register it).

This Debian webpage shows us the propietary firmware available and this webpage shows how to prepare you flash drive to install Debian GNU/Linux 6 in your server!

The procedure

First, download the image from the Debian's repository with propietary firmware.

Second, download the image to format the flash drive from here, in my case amd64 for the HP DL380 G7.

Third, prepare your flash drive in other Linux machine. Let /dev/sdX be the place where your flash drive is mounted.

zcat boot.img.gz > /dev/sdX
mkdir -p /mnt/pendrive
mount /dev/sdX /mnt/pendrive
cp firmware-6.0.2.1-amd64-netinst.iso /mnt/pendrive
umount /mnt/pendrive

Fourth, boot your server with the flash drive inserted to install the system from network. The firmware for the network card will be available (plus some others).

Enjoy!

Folding@Home in Debian GNU/Linux Squeeze amd64 as a service

I think distributed computing is fascinating, these days I have been learning about MPI, clusters and related stuff. The power of a lot of machines working collaboratively to solve a problem... amazing!, I love computing :-)

You know that a mayor part of time your CPU is not fully used because your processes are not all heavyweight all the time, lots of IO locks, dead times, etc. I mean, rarely ours CPUs are 100% used.


Folding@Home is a distributed computing project where protein folding is studied doing complex simulations, so complex and CPU demanding that the scientists turn to ask for help to the whole world. You can share some cycles of your CPU to the Science.

"Protein folding is linked to disease, such as Alzheimer's, ALS, Huntington's, Parkinson's disease, and many Cancers. Moreover, when proteins do not fold correctly (i.e. "misfold"), there can be serious consequences, including many well known diseases, such as Alzheimer's, Mad Cow (BSE), CJD, ALS, Huntington's, Parkinson's disease, and many Cancers and cancer-related syndromes."

I joined to help anonymously some years ago and I hope you can join us, create a team or just add yourself to the default group.

Check the webpage, they have been awarded and several results have been published.

I have installed the client in my dual boot machines (Windows/Linux) and in my home server.

I will show you how to install FAH in Debian GNU/Linux Lenny in a machine without X and in a service mode. Setting FAH as a service will allow it to start automatically every time the system boots up and you still are in charge because you can disable or even uninstall the service.

Log in as root or sudo as you like.

You should create a new user account by security reasons and according with the best practices suggested here (or here), the best place to put our client is /opt/fah.

# groupadd fah
# useradd -g fah fah --shell /bin/bash -d /opt/fah -m

From here you can download the installer, I chose FAH6.34-Linux64.tgz bacause my linux box is:


uname -a
Linux blogger 2.6.32-5-amd64 #1 SMP Tue Jun 14 09:42:28 UTC 2011 x86_64 GNU/Linux

wget http://www.stanford.edu/group/pandegroup/folding/release/FAH6.34-Linux64.tgz
tar xzf FAH6.34-Linux64.tgz
chmod u+x fah6

After that we may configure the client, buy we should do this as the fah user (will create configuration files and data):

su fah 

Then, we run the executable:

$ ./fah6

Note: Please read the license agreement (fah6 -license). Further
use of this software requires that you have read and accepted this agreement.

Ok, here we break the download of unit works [CONTROL+C] because we should setup fah as a service. It will continue from here when the binary be executed again anyway.

As root again, let's create /etc/init.d/fah with this content:

#!/bin/sh
### BEGIN INIT INFO

# Required-Start:    $syslog
# Required-Stop:     $syslog
# Default-Start:     2 3 4 5

check_config()
{
        if [ ! -e /opt/fah/client.cfg ]; then
                echo "FAH has not been configured!!!"
                exit 1
        fi
}

case "$1" in
        start)
                check_config
                echo -n "Starting FAH..."
                cd /opt/fah
                start-stop-daemon --start --quiet --chdir /opt/fah -b --chuid fah --exec /opt/fah/fah6
                echo "."
        ;;

        stop)
                echo -n "Stopping FAH..."
                start-stop-daemon --stop --quiet --oknodo --user fah
                echo "."                                                                                     
        ;;                                                                                                   
                                                                                                             
        *)                                                                                                   
                echo "Usage: /etc/init.d/fah {start|stop}"                                                   
                exit 1
esac

exit 0

We make it executable:

chmod u+x /etc/init.d/fah

And we setup the service but this is Squeeze so we use insserv instead of update-rc.d (check this).

insserv /etc/init.d/fah

Now, we start our new service for the first time:

invoke-rc.d fah start

We can see what is happening in the background using tail:

$ cd /op/fah

(This continues... [CONTROL+C])

And that is all. Top will show you the process a FahCore using 100% of one of your cores but with the highest nice value, that is to say, with the lowest scheduling priority. So, if you don't use the CPU, FAH will do and you will be helping some scientist to find the cure to some ugly illness.























Take a look at this ranking, these papers (78!), these awards or these videos. Finally meet Vijay Pande!

So, Will you join Folding@Home?

Truecrypt in Debian GNU/Linux Lenny x64

Sometimes you need to encrypt some files like documents, passwords, etc. and puntual encryption maybe just the solution with gpg. However, if you need to encrypt lots of files you should try TrueCrypt for a masive encryption.

So, what about a virtual encrypted partition containing all your files?

The following procedure was done in a remote machine through ssh: 

First, you need to download the installer from here according to your architecture.

uname -a
Linux felix 2.6.32-bpo.5-xen-amd64 #1 SMP Thu Oct 21 13:52:59 UTC 2010 x86_64 GNU/Linux

In my case: truecrypt-7.0a-linux-console-x64.tar.gz

Second, you need some dependencies (?):

apt-get install fuse-utils libdevmapper dmsetup

Third, you must install TrueCrypt:

tar xzf truecrypt-7.0a-linux-console-x64.tar.gz
./truecrypt-7.0a-setup-console-x64

TrueCrypt 7.0a Setup
____________________


Installation options:

 1) Install truecrypt_7.0a_console_amd64.tar.gz
 2) Extract package file truecrypt_7.0a_console_amd64.tar.gz and place it to /tmp

To select, enter 1 or 2: 1

Before you can use, extract, or install TrueCrypt, you must accept the
terms of the TrueCrypt License.

Installing Debian GNU/Linux 6 from network using a USB flash drive and HP firmware for HP DL360 G7

UPDATE: A better way!

To install Debian GNU/Linux 6 in a server HP Proliant DL360 G7 using the network installer and a USB flash drive I wrote a shell script. Maybe you find it useful too.

You must know there is some proprietary firmware needed for the server to install (network at least).

After doing a little research, the know-how is in these sites:


http://wiki.debian.org/HP/ProLiant
http://wiki.debian.org/DebianInstaller/NetbootFirmware

In my case, the target architecture was amd64 (x86-64), but you would need some little modifications for any other architecture.

Before to run the shell script you need:

1- the network installer image from http://cdimage.debian.org/debian-cd/6.0.0/amd64/iso-cd/debian-6.0.0-amd64-netinst.iso

2- A USB flash drive (250 MB minimum).

3- A linux machine where you can run the shell script, I used a Debian GNU/Linux  Lenny.

The shell script is interactive, will download some files and write the USB flash drive. Be careful, data will be destroyed (after confirmation) because of formatting!

Remember to grant the needed permissions: chmod u+x script.sh


Use it on your own risk .
