White Paper

Scope of this white paper


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 EMC 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/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/SuSE-release (up to SLES 11)

• cat /etc/os-release (SLES 12 and newer)

Example:

delhanar03:~ # cat /etc/SuSE-release Welcome to SLES for SAP Applications 11.3 (x86_64) - Kernel \r (\l)

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

• cat /etc/redhat-release (up to RHEL 6)

• cat /etc/os-release (RHEL 7 and newer)

Example:

delhanar03:~ # cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.5 (Maipo)

Current operating system version

Prerequisites


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 EMC has tested. Table 1. FusionIO software versions tested by Dell EMC

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

FusionIO driver version (only needed for R910 appliances)

https://dell-support.sandisk.com/

SAP HANA operating system revisions matrix


iomemory-vsl

fio-sysvinit

fio-firmware

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 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:

<SID>adm

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.

Upgrades


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

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

Post-upgrade 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.

Media download You can get an evaluation copy of an ISO image from the SUSE website.

Upgrade from SLES 11 SP1 to SP2 for SAP applications To upgrade from SLES 11 SP1 to SP2 for an SAP application, using Zypper:

1. To receive updates, ensure that the system is registered with SUSE.

2. Upgrade to the latest packages on SP1 by running the following command:

Upgrades


Recommended operating system settings for SAP HANA Determine if you must apply the settings that are described in the following links to your updated version of the operating system. You might also need to apply additional packages.

• SAP Note 2136965: SAP HANA DB: Recommended OS settings for RHEL 6.6

• SAP Note 2247020: SAP HANA DB: Recommended OS settings for RHEL 6.7

• SAP Note 2292690: SAP HANA DB: Recommended OS settings for RHEL 7

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

Clear version locks Before upgrading, determine if any version locks are set on the system by running the following command:

yum versionlock

If any package is displayed in red, clear that version lock.

For example:

[root@dellhana4 ~]# yum versionlock Loaded plugins: product-id, rhnplugin, security, subscription-manager, versionlock This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. This system is receiving updates from RHN Classic or RHN Satellite. kernel-2.6.32-431.29.2.el6.* kernel-firmware-2.6.32-431.29.2.el6.* kernel-headers-2.6.32-431.29.2.el6.* nss-softokn-freebl-3.14.3-12.el6_5.* nss-softokn-3.14.3-12.el6_5.* versionlock list done If any version locks these could be cleared by yum versionlock clear [root@dellhana4 ~]# yum versionlock clear Loaded plugins: product-id, rhnplugin, security, subscription-manager, versionlock This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. This system is receiving updates from RHN Classic or RHN Satellite. versionlock cleared Upgrade RHEL 6 for HANA series using Red Hat Satellite Server





Upgrades


White Paper

To get to the new release version, register the product with Red Hat and run the following command:

yum update

You can look up the current release information in /etc/redhat-release by running the following command:

cat /etc/redhat-release

To determine if you must apply any changes to the operating system settings, see Media download.

For more information, see the upstream documentation at the Red Hat Knowledgebase.

Upgrade RHEL 6.5 to RHEL 6.6 using media To mount a local RHEL 6.6 ISO or DVD and update to this version, follow the instructions in the Red Hat Knowledgebase.

Note: When you upgrade to RHEL 6.6 on NVMe-based R920 scale-up systems, the NVMe driver is removed. RHEL 6.6 provides its own NVMe driver.

1. Mount the RHEL 6.6 installation ISO to a directory such as /mnt.

2. Copy the media.repo file from the root of the mounted directory to /etc/yum.repos.d/ and set the permissions.

3. Edit the new repo file, changing the gpgcheck=0 setting to 1 and adding the following lines: enabled=1 baseurl=file:///mnt/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

4. Clear the related caches by running the following commands:

yum clean all

subscription-manager clean

5. Verify that you can get the packages list from the DVD repository and, if so, perform an update by running the following command:

yum -y update --disablerepo=* --enablerepo=<YOUR_REPO_NAME>

6. Update nss-softokn-freebl and glibc from the USB key.

reboot package-cleanup --oldkernels --count=1

7. Determine if you must apply any changes to the operating system settings.

For more information about changing operating system settings, see SAP Note 2136965: SAP HANA DB: Recommended OS settings for RHEL 6.6.





Upgrades


Upgrade RHEL 6.6 to RHEL 6.7 using EUS channel It is recommended that you subscribe the system to the EUS channel for long-term support of the RHEL 6 series. For a description of the process, see the Red Hat Knowledgebase.

Determine if any version locks are set as described in Recommended operating system settings for SAP HANA, and clear them before performing the upgrade.



Upgrade RHEL 6.7 to RHEL 7.2 using EUS channel The upgrade process that is described in the Red Hat Knowledgebase has been tested. Based on the pre-upgrade check, Red Hat does not advise upgrading these systems. For an upgrade to RHEL 7.x, request a reinstallation from a Dell EMC service partner.

The upgrade requires that the system be unregistered from the RHEL 6.7 EUS channel, registered to receive updates for RHEL 6.9, and then upgraded to that version.

Verify if any version locks are set as described in Recommended operating system settings for SAP HANA. If any version locks are set, clear them before the upgrade procedure.

If all errors and issues are fixed in advance, the system might be upgraded from RHEL 6.9 to RHEL 7.2.

Note: This procedure is only for experimental systems. It is neither supported nor recommended.

Upgrade RHEL 6.7 over RHEL 6.10 to RHEL 7.4 using EUS channel Red Hat offers an upgrade path from RHEL 6.7 over RHEL 6.10 to RHEL 7.4. The Red Hat Knowledgebase and the Product Enhancement Advisor describe this process. Based on the pre-upgrade check, Red Hat does not advise upgrading these systems. For an upgrade to RHEL 7.x, request reinstallation from a Dell EMC service partner.

Verify if any version locks are set as described in Recommended operating system settings for SAP HANA. If any version locks are set, clear them before the upgrade procedure.

Upgrade RHEL 7.4 to RHEL 7.5 (no E4S support) Other than the Red Hat documentation, there are no special considerations.

Upgrade RHEL 7.5 to RHEL 7.6 Other than the Red Hat documentation, there are no special considerations.

Note: Unlike RHEL 7.4, RHEL 7.5 has extended update service, which results in a shorter maintenance window. It is recommended to continue to use RHEL 7.4 and then upgrade to RHEL 7.6, which is the next EUS release, as soon as it is qualified for SAP HANA appliance workloads.
