Scope of this white paper This white paper describes the upgrade of an SAP HANA appliance to a later operating system version. The intention of this white paper is only to provide guidance for an easier upgrade path. This information comes without any warranty. Before performing an upgrade, see the official third-party documentation from SUSE, Red Hat, and VMware.

Note: This white paper is not intended as a step-by-step instruction document, and Dell Technologies does not support it as an official update procedure.

Prerequisites You need operating system root access to the SAP HANA appliance. The appliance must be registered with SUSE or Red Hat before you can upgrade to a later version using an operating system upgrade tool (for example, Zypper or YUM). If the appliance is a Dell EMC PowerEdge R910 server, the FusionIO driver version must be collected.

To determine if a supported upgrade path is available for your hardware and operating system version, see SAP HANA operating system revisions matrix.

SUSE To identify which operating system version and service pack you are running, run either of the following commands:

• cat /etc/os-release (SUSE Linux Enterprise Server 12 and later)

• cat /etc/SuSE-release (up to SUSE Linux Enterprise Server 11)

Example:

delhanar03:~ # cat /etc/os-release NAME="SLES" VERSION="12-SP4" VERSION_ID="12.4" PRETTY_NAME="SUSE Linux Enterprise Server 12 SP4" ID="sles" ANSI_COLOR="0;32" CPE_NAME="cpe:/o:suse:sles_sap:12:sp4"

White Paper

You can identify the currently running FusionIO driver by running the following command as a root user on the system:

delhanar01:~ # fio-status Found 1 ioDrive in this system Fusion-io driver version: 2.3.10 build 110 Adapter: ioDrive Fusion-io ioDrive 320GB, Product Number:FS1-004-320-CS SN:465353 External Power: NOT connected PCIE Power limit threshold: 24.75W Sufficient power available: Unknown Connected ioDimm module: fct0: Fusion-io ioDrive 320GB, Product Number:FS1-004-320-CS SN:465353 fct0 Attached as 'fioa' (block device) Fusion-io ioDrive 320GB, Product Number:FS1-004-320-CS SN:465353 Located in slot 0 Upper of ioDrive SN:465353 PCI:45:00.0

After you perform a kernel upgrade, you must rebuild the driver for the new kernel version to mount the block device /dev/fioa to /hana/log.

FusionIO drivers are available at the SanDisk Support website (through the security certificate warning).

Table 1 lists the software versions that Dell Technologies has tested. Table 1. Tested FusionIO software versions

Card Software version

FusionIO Gen 1 2.3.10

FusionIO Gen 2 3.2.3

FusionIO driver update to a later version (2.3.1 to 2.3.10) To update the driver:

1. Stop the SAP HANA database, back up all data available in /hana/log, and then unmount by running the following command:

unmount /hana/log

2. Search for and remove the earlier versions of the driver and tools by running the following command:

rpm –qa|grep ‘(iomemory|fio)’

The command lists the following set of packages: fio-common, fio-util, iomemory-vsl, fio-sysvinit, fio-firmware

FusionIO driver version (only needed for R910 appliances)

3. Download the RPM packages in the preceding list from the SanDisk Support website (through the security certificate warning), and install them on the system.

See Rebuilding the kernel module for a different kernel version.

4. After the driver version is updated, perform a firmware update by running the following command:

fio-update-iodrive /usr/share/fio/firmware/iodrive_107053.fff

This step enables you to access the content of the FusionIO card.

Note: If the firmware is not updated, the card remains in minimal mode.

Rebuilding the kernel module for a different kernel version You need the source package of the version of the tools and driver that you are running on your system. For this white paper, we used version 2.3.10 as the base version. Build the kernel package by running the following command:

rpmbuild --rebuild iomemory-vsl-2.3.10.110-1.0.src.rpm

To identify the latest version of the service pack that you can use with an appliance, see Certified and Supported SAP HANA Hardware Directory.

Upgrades Before you perform an upgrade, it is recommended that you create a backup of the SAP HANA database and the operating system.

Stopping the database on scale-out systems The procedure varies depending on your setup. To stop the database on a scale-out system:

1. Shut down the SAP HANA database by running the following command:

sapcontrol –nr <InstanceId> -function StopSystem HDB 1000 500

2. Ensure that the database is stopped on all nodes by running either of the following commands:

ps faux|grep [h]db

ps faux|grep sapadm

If the OCFS2 is not defined as a cluster resource, then follow these steps:

1. Unmount the OCFS2 file system on all nodes by running the following command:

umount –a –t ocfs2

2. Ensure that the OCFS2 file system is not mounted if a process is still accessing it.

The output of the command grep ocfs2 /proc/mounts must be empty. If it is not, identify the process that is blocking the unmount by running the following command:

lsof /hana/shared

Kill that process and repeat step 3.

3. Stop the cluster on all nodes by running the following command:

/etc/init.d/openais stop

4. When the upgrade is complete, restart the nodes one after the other.

5. Verify that the OCFS2 volumes are mounted correctly and the database is available.

Cluster maintenance mode Before you perform an upgrade, it is recommended that you place the cluster into maintenance mode or shut it down.

You can place the cluster into maintenance mode by running the following command:

crm configure property maintenance-mode=true

White Paper

You can disable the mode later by running the following command:

crm configure property maintenance-mode=false

You can disable the cluster service before an upgrade by running the following command:

chkconfig openais off

After a successful update, you can enable the cluster by running the following command:

chkconfig openais on

Postupgrade activities After you perform an upgrade, verify that all recommended operating system settings have been implemented.

If an SAP HANA Hardware Configuration Check Tool (HWCCT) is used for validation, ensure that you download the latest patches from SAP Note 2161344: HWCCT patch note.

For information about updating SAP HANA/ operating system versions to a later version, see the Linux Operating System with SAP HANA Reference Guide.

See the SUSE Linux Enterprise Server Upgrade Guide to consolidate the available upgrade path, as shown in the following figure from the SUSE Linux Enterprise Server website:
