○ Reboot the machine and use the new kernel:

● Install the base package group and xfs tools:

yum -y groupinstall base

yum -y install xfsprogs

● Create local storage for SAP HANA.

○ Check for empty devices

# lsblk -f

NAME FSTYPE LABEL UUID MOUNTPOINT

sda

├─sda1 /boot

└─sda2

sdb

○ Create a disk partition.

○ Let us assume that disk /dev/sdb is our free device

○ If you have less than 2 TB free space on the disk, use fdisk

# fdisk -cu /dev/sdb

Command (m for help):c

○ If you have 2 TB or more free space, use parted and the GPTlabel

# parted /dev/sdb

○ Create PV with pvcreate /dev/<disk-partition>

○ Expand VG with vgextend vg00 /dev/<disk-partition>

○ Check with pvs and vgs

● Create logical volumes for the SAP HANA instance according to your sizing. This is an example for the

logical volumes you could create for a host with 96 GiB of memory:

# lvcreate -L96G -n lv_hana_shared vg00

# lvcreate -L288G -n lv_hana_data vg00

# lvcreate -L96G -n lv_hana_log vg00

# lvcreate -L50G -n lv_usr_sap vg00

For more information about sizing SAP HANA, see Appendix F - Table to Calculate the Size of the Logical

Volumes in this document and Sizing SAP HANA in the SAP HANA Master Guide.
