Pre-requisites for the SAP HANA instance before installation

Please log in as root user and create the following directories:

mkdir /hana

mkdir /hana/shared

mkdir /usr/sap

mkdir /hana/data

mkdir /hana/data/HDB

mkdir /hana/log

mkdir /hana/log/HDB

With the following command, we will format our 4 volumes with the ext3 file system (proceed with “y”):

mkfs -t ext3/dev/sdb

Proceed this way to format the remaining volumes:

mkfs -t ext3/dev/sdc

mkfs -t ext3/dev/sdd

mkfs -t ext3/dev/sde

Next, we will edit the file  vi/etc/fstab and add the following values, so our volumes will be automatically mounted every time we restart our system. With this, we will achieve that they always will be available as soon as we log in.

/dev/sdb             /usr/sap             ext3       defaults              0 0

/dev/sdc             /hana/data           ext3       defaults              0 0

/dev/sdd             /hana/log            ext3       defaults              0 0

/dev/sde             /hana/shared         ext3       defaults              0 0

With the command mount -a, all volumes displayed within fstab will automatically be mounted. Should you need to know and/or check, which volumes you have created and where they have been mounted to, you can use the df -h command for that:

For the rest of the process, a Java package will be required. You can easily install it on your Linux machine using the following commands:

wget http://javadl.sun.com/webapps/download/AutoDL?BundleId=83375

mv “FILE_NAME” java-linux-x64.rpm

Next, type in the following command in order to start unpacking your Java package:

rpm -ivh java-linux-x64.rpm

It is up to you whether you would like to download and decompress the data on a Windows machine or a Linux machine. Keep in mind, though, that the decompressed data must be readily available on your Suse Linux machine.

Within the Marketplace, we download the 10 RAR files – for instance on a Windows machine – and decompress these. For this, you will need a decompression tool such as WinRAR or 7-Zip.

The decompressed files can now be transferred to our SUSE server e.g. via SFTP:

Switch to the directory *DATA_UNITS/HDB_SERVER_LINUX_X86_64 and make the data executable with the following commands:

find -name  hdbinst   -exec chmod 744 {} +
find -name  hdbsetup  -exec chmod 744 {} +

find -name  hdbuninst -exec chmod 744 {} +
find -name  sdbrun    -exec chmod 744 {} +

In order to prevent the installation from aborting due to a hardware check, we must deactivate this functionality. Please note that the code below can only be deployed if you have the scripting language Python on your machine. I will just “guess” that you already have Python on your machine:

export IDSPISPOPD=”1″

python

>>> import os

>>> ‘IDSPISPOPD’ in os.environ.keys()

True

>>> quit()

 

Please make the file hdblcm within the subdirectory /HDB_LCM_LINUX_X86_64 executable:

chmod 744 hdblcm

Begin installation. Type in:

./hdblcm
