Setup SAP HANA server 

1. Check OS Version
2. Setup hostname
3. Setup swap space
4. Create a mount point for SAP Application
5. Install packages for SAP HANA

Check OS Version

Find OS Version:

cat /etc/os-release

Output

demo21:/dev/disk/by-id # cat /etc/os-release

Setup hostname

hostnamectl set-hostname demo21.xxx.com

Setup swap space

cat /proc/swaps
mkdir -p /var/lib/swap
dd if=/dev/zero of=/var/lib/swap/swapfile bs=1M count=8192
mkswap /var/lib/swap/swapfile
swapon /var/lib/swap/swapfile
cat /proc/swaps

#/etc/fstab

Create Mount point

mkdir -p /hana

mkdir -p /hana/log

mkdir -p /hana/data

mkdir -p /hana/shared

Update /etc/fstab file

The space- or tab-separated fields within each row (typically aligned in columns, as above, but this is not a requirement) must appear in a specific order, as follows:

• Device-spec – The device name, label, UUID, or other means of specifying the partition or data source this entry refers to.
• Mount-point – Where the contents of the device may be accessed after mounting; for swap partitions or files, this is set to none.
• fs-type – The type of file system to be mounted.
• Options – Options describing various other aspects of the file system, such as whether it is automatically mounted at boot, which users may mount or access it, whether it may be written to or only read from, its size, and so forth; the special option defaults refers to a predetermined set of options depending on the file system type.
• dump – A number indicating whether and how often the file system should be backed up by the dump program; a zero indicates the file system will never be automatically backed up.
• pass – A number indicating the order in which the fsck program will check the devices for errors at boot time; this is 1 for the root file system and either 2 (meaning check after root) or 0 (do not check) for all other devices.
