I used to
do this using Windows and a HP P410 Smart Array controller, however that controller is
no longer available.




The online ROM
flash component is not an option because I don't own HP Smart Array controller. Neither
is the href="http://www8.hp.com/us/en/products/server-software/product-detail.html?oid=5104018#!tab=features"
rel="nofollow noreferrer">HP Service Pack for ProLiant + USB key/stick an
option because that requires a ProLiant server.



Answer




Upgrading the HP SAS expander is possible using Linux and a SAS
HBA.
Note: Flashing firmware to a SAS
expander will likely not work when the expander is connected to a SAS
RAID controller because that controller might hide all
devices behind it from the OS. An example of a SAS HBA is href="http://www.supermicro.com/products/accessories/addon/AOC-SAS2LP-MV8.cfm"
rel="noreferrer">Supermicro
SAS2LP-MV8.



In case you
haven't got Linux, you can use a Linux Live CD. You could try the href="http://www.ubuntu.com/download/desktop/" rel="noreferrer">most recent Ubuntu
Live CD. A 32-bit download will do. 64-Bit will
also work.



1.
Prerequisites





  1. Start
    a Linux terminal
    That is
    Ctrl+Alt+T using
    the Ubuntu LiveCD.


  2. Make
    sure your internet connection is working
    To download and install
    additional components


  3. Make
    sure your SAS expander card is detected in Linux
    #
    lsscsi -g | grep HP
    Should return something like: />[6:0:0:0] enclosu HP HP SAS EXP Card 2.08 - /dev/sg1 />[6:0:1:0] enclosu HP HP SAS EXP Card 2.10 -
    /dev/sg2




2.
Setup utility



You use
sg_write_buffer version ≥ 1.15 to download microcode when the
expander is connected to a host bus adapter (HBA). To download and install this utility
in 32-bit Ubuntu or Debian, use:



#
            curl -O http://sg.danny.cz/sg/p/libsgutils2-2_1.39-0.1_i386.deb &&
            

curl -O http://sg.danny.cz/sg/p/sg3-utils_1.39-0.1_i386.deb
            && 
dpkg -i
            *_1.39-0.1_i386.deb


The
sg_write_buffer utility version ≥ 1.15 — distributed in href="http://sg.danny.cz/sg/sg3_utils.html"
rel="noreferrer">sg3_utils version ≥ 1.39 — added
a --bpw option to download in small chunks. An expander might
require a small chunk size like 4096
bytes.



3. Get and unpack HP
firmware
image




  1. Get the
    expander firmware image file, for example href="http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=3923501&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3Didx%253D3%257CswItem%253DMTX_07e17cded9e8409ea4b9d7ea74%257CswEnvOID%253D54%257CitemLocale%253D%257CswLang%253D%257Cmode%253D4%257Caction%253DdriverDocument&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken"
    rel="noreferrer">version 2.10 (C) — dated 9 Sep 2014: /># curl -O
    http://downloads.hpe.com/pub/softlib2/software1/sc-linux-fw-array/p6670438/v96061/CP022989.scexe     />Although they sound like Windows/DOS executables,
    .scexe files from HP are really Linux executable scripts that
    you can view in a text editor (at least the first
    part).



  2. Running
    a 64-bit Linux and having issues with the next command? Then make sure you can run
    32-bit executables. The commands in Ubuntu are:
    # dpkg
    --add-architecture i386 && apt-get update && apt-get install
    libstdc++6:i386


  3. To
    extract the firmware image from this .scexe file:
    # mkdir tmp
    && chmod +x CP022989.scexe && ./CP022989.scexe --unpack=tmp &&
    mv tmp/PUF21000.bin . && rm -r
    tmp/




4.
Flash SAS expander



When the expander to be
upgraded/flashed is named sg1 (check with
lsscsi -g | grep HP),
use:



# sg_write_buffer
            --mode=dmc_offs_defer --bpw=4096 --in=PUF21000.bin /dev/sg1
# sg_write_buffer
            --mode=activate_mc
            /dev/sg1



Older
devices might only support --mode=0x7. Mode
0x7 is also known as dmc_offs_save,
which does download microcode with offsets, save and
activate.



5. Remove temporary
files



# rm
            PUF21000.bin


You might
need to unload (for instance modprobe -r mvsas) and load (f.e.
modprobe mvsas) your HBA module again or
reboot to reflect the firmware version changes in
lsscsi -g output.

iLO 3 Firmware Update (HP Proliant DL380 G7)

The iLO web interface allows me to upload a .bin file ( Obtain the firmware image (.bin) file from the Online ROM Flash Component for HP Integrated Lights-Out. ) The iLO web interface redirects me to a page in the HP support website ( http://www.hp.com/go/iLO ) where I am supposed to find this .bin firmware, but no luck for me. The support website is a mess and very slow, badly categorized and generally unusable. Where can I find this .bin file? The only related link I am able to find asks me about my server operating system (what does this have to do with the iLO?!) and lets me download an .iso with no .bin file And also a related question: what is the latest iLO 3 version? (for Proliant DL380 G7, not sure if the iLO is tied to the server model)

linux - Awstats - outputting stats for merged Access_logs only producing stats for one server's log

I've been attempting this for two weeks and I've accessed countless number of sites on this issue and it seems there is something I'm not getting here and I'm at a lost. I manged to figure out how to merge logs from two servers together. (Taking care to only merge the matching domains together) The logs from the first server span from 15 Dec 2012 to 8 April 2014 The logs from the second server span from 2 Mar 2014 to 9 April 2014 I was able to successfully merge them using the logresolvemerge.pl script simply enermerating each log and > out_putting_it_to_file Looking at the two logs from each server the format seems exactly the same. The problem I'm having is producing the stats page for the logs. The command I've boiled it down to is /usr/share/awstats/tools/awstats_buildstaticpages.pl -configdir=/home/User/Documents/conf/ -config=example.com awstatsprog=/usr/share/awstats/wwwroot/cgi-bin/awstats.pl dir=/home/User/Documents/parced -month=all -year=all...

linux - How can I get my mediawiki to stop thinking I have cookies disabled?

I've searched half a day for how to resolve this issue, and can't figure it out. Shortly after I made my wiki a simple private wiki according to the instructions at Mediawiki's website, it started giving me this weird login error message: Wiki uses cookies to log in users. You have cookies disabled. Please enable them and try again. If I remove those private wiki settings, the error disappears, even if I try logging in. But I need it to be a private wiki for only my team. So what do I do? Here's what I've done so far. Just to be safe, after ever change, I try rebooting Apache using: sudo /etc/init.d/apache2 restart In my php.ini file, I have the following set: session.save_path = "/var/lib/php5" session.cookie_secure = secure session.cookie_path = /tmp session.cookie_domain = my server's internal URL (should I even set this? this field was blank before, but not commented out) session.referer_check = Off I ran the following to ensure that the fold...
