Installing Centos on HP Proliant DL360e Gen8 with B120i controller

Advertisements

Installing centos 5.7 on HP Proliant DL360e Gen8 was a headache. First of all it comes with HP B120i Dynamice smart array controller which centos or redhat doesnt detect by default. We have to install a source driver from HP separately to detect this controller.

At first I created the RAID 1 logical array using the acu(array configuration utility) oh HP server. And started installing Centos. Installation proceeded but at the time of drive select it showed the two 500GB hard disks instead of one single raid 1 device. That means os couldn't detect the storage controller.

After a lot of googling and HP customer support I found the steps to do it.
HP B120i driver is supported from Redhat/Centos 5u7 onwards.

Centos installing both i386 and x86_64 rpms

If you are running rhel/centos x86_64 systems,you can see redhat/centos has installed both i386 and x86_64 rpms. It will create a lot of dependency problems, conflicts etc.

in case if you are installing httpd you may end up in glibc duplicate errors.

rpm -qa | grep glibc
glibc-devel-2.5-65.el5_7.1
glibc-devel-2.5-65.el5_7.1
!--more-->
To view the architecture of installed files add the following line to ~/.rpmmacros
#vi ~/.rpmmacros
%_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch}
Save the file.

Now when querying
# rpm -qa | grep glibc
glibc-devel-2.5-65.el5_7.1.x86_64
glibc-devel-2.5-65.el5_7.1.i386


You can solve this problem by adding the following lines to /etc/yum.conf
exactarch=1
exclude=*.i386 *.i586 *.i686

Also remove all the duplicate files as follows.
yum remove glibc-devel-2.5-65.el5_7.1.i386
