1. Create and attach three additional disks to node-a and node-b to support the installation of SAP HANA. The device names used in this example may vary depending on your environment (e.g., /dev/xvdb instead of /dev/sdb). Note that these disk sizes are used for evaluation purposes only. Consult the relevant documentation from SAP, your cloud provider, and any third-party storage provider when provisioning resources in a production environment.
Device Name
Minimum Size
Mount Point
/dev/sdb 20GB /hana/log
/dev/sdc 30GB /hana/data
/dev/sdd 60GB /hana/shared
  1. Execute the following commands on both node-a and node-b to create a /dev/sdb1 partition with an xfs file system.
[root@node-a ~]# parted /dev/sdb --script mklabel gpt mkpart xfspart xfs 0% 100%

[root@node-a ~]# mkfs.xfs /dev/sdb1
meta-data=/dev/sdb1    isize=512   agcount=4, agsize=1310592 blks
         =             sectsz=4096 attr=2, projid32bit=1
         =             crc=1       finobt=1, sparse=1, rmapbt=0
         =             reflink=1
data     =             bsize=4096  blocks=5242368, imaxpct=25
         =             sunit=0     swidth=0 blks
naming   =version 2    bsize=4096  ascii-ci=0, ftype=1
log      =internal log bsize=4096  blocks=2560, version=2
         =             sectsz=4096 sunit=1 blks, lazy-count=1
realtime =none         extsz=4096  blocks=0, rtextents=0

[root@node-a ~]# partprobe /dev/sdb1

Repeat these commands for /dev/sdc and /dev/sdd on both node-a and node-b.

  1. Execute the following command to create the mount points for the SAP HANA file systems:
[root@node-a ~]# mkdir -p /hana/{log,data,shared}
  1. Use the blkid command to view the UUID’s for each partition.
[root@node-a ~]# blkid | sort
/dev/sdb1: UUID="f058a8de-4e17-4c1d-97a3-a2672aff58dd" TYPE="xfs" PARTLABEL="xfspart" PARTUUID="f780893d-bd61-4beb-89df-fb23ea04f16e"
/dev/sdc1: UUID="c0ab7218-ec24-4a6f-b883-37e505ec806c" TYPE="xfs" PARTLABEL="xfspart" PARTUUID="34c47333-7174-468c-b8f0-a3491cd0fe0c"
/dev/sdd1: UUID="057f4f63-8fb3-486b-82b5-49fbbd4914cc" TYPE="xfs" PARTLABEL="xfspart" PARTUUID="0c9cc7d3-9622-4b3f-8949-e744a02af466"
  1. Referencing the UUID’s found in step 3, add the following entries to /etc/fstab on node-a and node-b to allow the file systems to be mounted at boot. Replace the sample UUID’s given in this example with the UUID’s of the appropriate partitions on your systems.
UUID=f058a8de-4e17-4c1d-97a3-a2672aff58dd       /hana/log      xfs     defaults        0 0
UUID=c0ab7218-ec24-4a6f-b883-37e505ec806c       /hana/data       xfs     defaults        0 0
UUID=057f4f63-8fb3-486b-82b5-49fbbd4914cc       /hana/shared    xfs     defaults        0 0
  1. Execute the following commands on node-a and node-b to mount the SAP HANA file systems on both nodes:
mount /hana/log
mount /hana/data
mount /hana/shared

The file systems are now prepared for SAP HANA installation.
