Purpose of this guide The purpose of this guide is to provide an introduction for customers who are new to the IBM Cloud environment and would prefer a quick start format versus more detailed documentation. Two sample configurations help you through the ordering process to the start of the SAP installation. The first configuration sample is the smallest one possible a single node 32 GB RAM server. The second is an advanced configuration of two nodes, a 32 GB RAM server and a 256 GB RAM server with an external storage configuration. The disk layout might vary if you do not choose the same options in the examples. The sample layouts may not be your preferred layout; the purpose is to show you two possibilities if you are not experienced with the Linux operating system. Note that you can find an example of how to attach external storage to your provisioned server under Provisioning external storage to your server. IBM has unified their SoftLayer, IBM Bluemix, and IBM Cloud offering solutions, making the SoftLayer and Bluemix infrastructures synonymic for the IBM Cloud IaaS offering. See https://www.ibm.com/blogs/bluemix/2017/10/bluemix-is-now-ibm-cloud/ for more information. 4 Copyright IBM Corp. 2017. All rights reserved. without prior written permission of IBM.

Preparing your server for the SAP installation (32 GB) A public IP is being used for remote access, which means you can connect to your server through an ssh client (for example, putty on Microsoft Windows). Use the public IP address displayed in the Device List for your device. The root password for your server is also displayed; be sure to click the Show Password checkbox to see it. Figure 10 Device List - find password Partitioning and file systems For the single-node example, a server with one logical disk (on RAID1) was ordered. There is one mirrored disk appearing in the operating system (OS) with one large root filesystem equal to the total size of disk (with some space used for /boot). The following is just one possible approach for a layout. For production use, you may want to follow the sizing information for your system as other layouts may better cater to your needs or SAP requirements. Below, the three directories required for the SAP installation; /usr/sap, /sapmnt and /db2 have been created: [root@e2e1270 ~]# mkdir /sapmnt [root@e2e1270 ~]# mkdir /usr/sap [root@e2e1270 ~]# mkdir /db2 In regard to storage, the server is now prepared for further installation steps. Refer to RPM package prerequisites to continue with your SAP installation. The information within it will help make graphical access to your server easier. 12 Copyright IBM Corp. 2017.

Preparing your server for the SAP installation (256 GB) A public IP is being used for remote access, which means you can connect to your servers through an ssh client (for example, putty on Windows). Use the public IP addresses that are displayed in the Device List for your device. The root passwords for your servers are also displayed; be sure to click the Show Password checkbox to see them. Figure 19. Device List - find password Partitioning and file systems For the three-tier example, a 256 GB server (database server) with one logical disk (on RAID10) was ordered, as well as a 32 GB server (application server) with one logical disk (on RAID 1). Both servers come with one large root filesystem equal to the total size of disk (with some space used for /boot). For the 32 GB server, follow the steps 1 to 10 in Preparing your server for the SAP installation (32 GB); then continue with steps 11 to 14, but replacing /db2 with /usr/sap /sapmnt and /usr/sap/trans will be created and the network file system (NFS) exported from the database server, which will also keep the Advanced Business Application Programming (ABAP) SAP Central Service (ASCS) instance. The following is just one possible approach for a layout. For production use, you may want to follow the sizing information for your system as other layouts may better cater to your needs or SAP requirements, or you might want to use quotas. The required directories for installing the SAP software will need to be created /sapmnt, /usr/sap and /db2 using the following commands: [root@ e2e2690 ~]# mkdir /sapmnt [root@ e2e2690 ~]# mkdir /usr/sap [root@ e2e2690 ~]# mkdir /db2 The server is now prepared for further installation steps in regard to storage. See Network and NFS considerations for three-tier setup for a description of the network layout and specific steps for the SAP installation. Copyright IBM Corp. 2017. All rights reserved. 19 without the prior written permission of IBM.

Network and NFS considerations for three-tier setup If you are planning to install a three-tier setup, you need to prepare the network setup accordingly. For the sample setup, a 256 GB database server (named e2e2690) and a 32 GB application server (named e2e1270) were deployed. The database server will also host the ASCS instance. Adding the IPs on the private network to your /etc/hosts will help with upcoming steps and make sure that SAP internal network traffic will go through the right network. Figure 20. Sample of three-tier set up 1. Log in to the machines and find their private network configuration. [root@e2e2690 ~]# ifconfig bond0 bond0 Link encap:ethernet HWaddr 0C:C4:7A:66:2D:A8 inet addr:10.17.139.35 Bcast:10.17.139.63 Mask:255.255.255.192 inet6 addr: fe80::ec4:7aff:fe66:2da8/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:128080 errors:0 dropped:0 overruns:0 frame:0 TX packets:25491 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:19137850 (18.2 MiB) TX bytes:3426015 (3.2 MiB) [root@e2e2690 ~]# ifconfig bond1 bond1 Link encap:ethernet HWaddr 0C:C4:7A:66:2D:A9 inet addr:208.43.211.118 Bcast:208.43.211.127 Mask:255.255.255.224 inet6 addr: fe80::ec4:7aff:fe66:2da9/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:289610 errors:0 dropped:0 overruns:0 frame:0 TX packets:109371 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:31216160 (29.7 MiB) TX bytes:18591947 (17.7 MiB) 20 Copyright IBM Corp. 2017. All rights reserved. without prior written permission of IBM.

In this example, 10.17.139.35 is the private IP of the database server; it is from one of the IP ranges from RFC 1597. You can determine the IP of the application server, too, and add both IPs to both servers /etc/hosts. [root@e2e2690 ~]# cat /etc/hosts 127.0.0.1 localhost.localdomain localhost 208.43.211.118 e2e2690.saptest.com e2e2690 10.17.139.35 e2e2690-priv 10.17.139.46 e2e1270-priv On e2e1270 add the two last lines, too. 2. Install NFS software nfs-utils on both servers. [root@e2e2690a ~]# yum install nfs-utils Make sure you start and register the rpcbind and NFS service on the database server. [root@e2e2690 ~]# service rpcbind start [root@e2e2690 ~]# chkconfig nfs on [root@e2e2690 ~]# service nfs start 3. Use NFS to export /sapmnt and /usr/sap/trans from the database server to the application server by adding the required entry to /etc/exports of the database server. /sapmnt/c10 /usr/sap/trans 10.17.139.46(rw,no_root_squash,sync,no_subtree_check) 10.17.139.46(rw,no_root_squash,sync,no_subtree_check) The sample value C10 needs to be replaced with the SAP System ID for your SAP system. You must create the directory before you export it. Run the following from the command line of the database server: [root@e2e2690 ~]# mkdir /sapmnt/c10 [root@e2e2690 ~]# mkdir -p /usr/sap/trans [root@e2e2690 ~]# exportfs -a 4. Mount the NFS share on the application server by adding the below entry to its /etc/fstab and mount it from the command-line. e2e2690-priv:/sapmnt/c10 /sapmnt/c10 nfs defaults 0 0 e2e2690-priv:/usr/sap/trans /usr/sap/trans nfs defaults 0 0 5. Create the target directories on the application server and mount them: [root@e2e1270 ~]# mkdir -p /sapmnt/c10 [root@e2e1270 ~]# mkdir /usr/sap/trans [root@e2e1270 ~]# mount /sapmnt/c10 [root@e2e1270 ~]# mount /usr/sap/trans Your servers are now prepared to host the components of a distributed SAP installation. See Provisioning external storage to your server for information on how to provision external storage for backup purposes to the database server. Further installation preparation will be performed in Installing your SAP landscape. Copyright IBM Corp. 2017. All rights reserved. 21 without the prior written permission of IBM.

Provisioning external storage to your server External storage can be added to your provisioned server(s) if you want to use it as a backup device or use a snapshot to quickly restore your database in a test environment. In the example, block storage will be used for both archiving log files of the database and online and offline backups for the database. The fastest block storage (4 IOPS per GB) was selected to help assure a minimum backup time. Slower block storage may be sufficient for your needs. External storage is ordered through the Customer Portal. 1. Open a browser window and log in to https://control.softlayer.com. 2. Click the Log in with IBMid button. 3. Enter your IBMid or email and click the Continue button. 4. Enter your Password and click the Sign in button. 5. Select Storage > Block Storage. Figure 21. Storage drop-down menu 6.

Figure 26. Authorizing your hosts for storage 12. Click the Submit button. 13. Check the status of your provisioned storage under Devices > (select your device) > Storage tab. 14. Note the Target Address and iscsi Qualified Name (IQN) for your server (iscsi initiator) as well as the username and password for authorization with the iscsi server. You will need that information in the following steps. Now you would follow the steps in Mounting Block Storage volumes on Linux under https://console.bluemix.net/docs/infrastructure/blockstorage/accessing_block_storage_linux. html#connecting-to-mpio-iscsi-luns-on-linux to make your storage accessible from your provisioned server.

In the sample deployment, the data retrieved from the Storage tab was Target IP: 10.2.62.78 IQN: iqn.2005-05.com.softlayer:sl01su276540-h896345 User: SL01SU276540-H896345 Password: EtJ79F4RA33dXm2q 1. Enter the following based on the retrieved information: [root@e2e2690 ~]# cat /etc/iscsi/initiatorname.iscsi InitiatorName=iqn.2005-05.com.softlayer:SL01SU276540-H896345 An existing entry might have to be replaced in /etc/iscsi/initiatorname.iscsi. 2. Add the following lines to the bottom of /etc/iscsi/iscsid.conf: [root@e2e2690 ~]# tail /etc/iscsi/iscsid.conf # it continue to respond to R2Ts. To enable this, uncomment this line # node.session.iscsi.fastabort = No node.session.auth.authmethod = CHAP node.session.auth.username = SL01SU276540-H896345 node.session.auth.password = EtJ79F4RA33dXm2q discovery.sendtargets.auth.authmethod = CHAP discovery.sendtargets.auth.username = SL01SU276540-H896345 discovery.sendtargets.auth.password = EtJ79F4RA33dXm2q 3. Replace the username and password values (in italics) with those that you noted during the last step of the previous section 4. Discover the iscsi target by entering the following: [root@e2e2690 ~]# iscsiadm -m discovery -t sendtargets -p "10.2.62.78" 10.2.62.78:3260,1031 iqn.1992-08.com.netapp:tor0101 10.2.62.87:3260,1032 iqn.1992-08.com.netapp:tor0101 5. Set the host to automatically log into the iscsi array [root@e2e2690 ~]# iscsiadm -m node -L automatic 6. Install and start the multipath daemon. [root@e2e2690 ~]# yum install device-mapper-multipath [root@e2e2690 ~]# chkconfig multipathd on [root@e2e2690 ~]# service multipathd start 26 Copyright IBM Corp. 2017. All rights reserved. without prior written permission of IBM.

After completing all the commands in Mounting Block Storage volumes on Linux, another LUN will appear in the multipath output. [root@e2e2690 ~]# multipath -ll 3600a098038303452543f464142755a42 dm-9 NETAPP,LUN C-Mode size=500g features='3 queue_if_no_path pg_init_retries 50' hwhandler='1 alua' wp=rw -+- policy='round-robin 0' prio=50 status=active `- 10:0:0:169 sde 8:64 active ready running `-+- policy='round-robin 0' prio=10 status=enabled `- 9:0:0:169 sdf 8:80 active ready running You can now use the multipath device as you would use any disk device. A device path will appear under /dev/mapper/3600a098038303452543f464142755a42. Take the sample, /etc/multipath.conf from Appendix A and create it accordingly on your server. Be aware that special characters or DOS-like carriage returns and line-feed entries wrongly transferred from the document might lead to unexpected behaviour. Make sure you have an ASCII Unix file after copying the contents. Adapt the multipath block from /etc/multipath.conf to create an alias of the path to access the device under /dev/mapper/mpath1. multipaths { multipath { wwid 3600a098038303452543f464142755a42 alias mpath1 } } 5. Restart multipathd; you can now create the /backup filesystem and mount on the block device. [root@e2e2690 ~]# service multipathd restart [root@e2e2690 ~]# mkfs.ext4 /dev/mapper/mpath1 [root@e2e2690 ~]# mkdir /backup [root@e2e2690 ~]# mount /dev/mapper/mpath1 /backup 6. Check the file systems on both servers; you should see output like the following: [root@e2e1270 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 879G 1,5G 833G 1% / tmpfs 16G 0 16G 0% /dev/shm /dev/sda1 248M 63M 173M 27% /boot /dev/sdb2 849G 201M 805G 1% /usr/sap db2690-priv:/usr/sap/trans db2690-priv:/sapmnt/c10 165G 59M 157G 1% /usr/sap/trans 165G 59M 157G 1% /sapmnt/c10 Copyright IBM Corp. 2017.

Installing your SAP landscape RPM package prerequisites An SAP installation requires certain prerequisites with regards to the packages installed on the OS and the OS daemons running. Please refer to the latest installation guides and support notes from SAP for an up-to-date list of these prerequisites. As of the writing of this guide, two additional packages were required for an SAP NetWeaver installation: compat-sap-c++: Achieves compatibility of the C++ runtime with the compilers used by SAP uuidd: Maintains OS support for the creation of UUIDs 1. Check if uuid daemon (uuidd) is installed. If it s not, install and start it. [root@e2e2690 ~]# rpm -qa grep uuidd [root@e2e2690 ~]# yum install uuidd [root@e2e2690 ~]# chkconfig uuidd on [root@e2e2690 ~]# service uuidd start 2. Follow SAP note 2195019 and install package compat-sap-c++ and create a specific soft-link, which is required by the SAP binaries. [root@e2e2690 ~]# yum install compat-sap-c++... [root@e2e2690 ~]# mkdir -p /usr/sap/lib [root@e2e2690 ~]# ln -s /opt/rh/sap/lib64/compat-sap-c++.so /usr/sap/lib/libstdc++.so.6 Download your SAP software Log in to the SAP Service Marketplace (https://support.sap.com/swdc) and download the required digital versatile discs (DVDs) to a local share drive and then transfer them to your provisioned server. Another option is to download the SAP Software Download Manager, install it on your target server and directly download the DVD images to the server. See http://service.sap.com for more information on the SAP Software Download Manager. Note that you will need an S-User ID and the Download Software authorization when downloading the DVDs from the SAP Service Marketplace. See https://websmp106.sapag.de/~sapidp/012002523100008495752016e/ if you need to request an S-User ID. Preparation for SAP s Software Provisioning Manager (SWPM) graphical user interface (GUI) Depending on your network bandwidth and latency, you may want to run the SAP SWPM GUI remotely in a virtual network computing (VNC session). Another option is to have the GUI running locally and connect to SWPM on the target machine. For the second option, please consult the SWPM documentation; the first option is demonstrated below. This option installs a VNC server, which might not be in line with hardening your operating system. You will want to make sure you are meeting your security measures.

1. Use the following command to install a VNC server, an X11 window manager and a console tool to run SWPM s GUI in a remote session. [root@e2e2690 ~]# yum install tigervnc-server... The command in step 1 will install several dependent packages on your server. Next, you will need an X11 window manager the smallest, lightest and oldest of which is twm; it is included in every Linux distribution. 2. Use the following command to install the window manager. [root@e2e2690 ~]# yum install twm 3. Install a terminal emulator (e.g., xterm): [root@e2e2690 ~]# yum install xterm 4. Start the VNC server from the command-line: [root@e2e2690 ~]# vncserver You will now require a VNC client program; there are multiple implementations available for all operating systems at no cost. Typically, you will need port 590X (where X is the number of the servers running, starting at 1) to be accessible from your client. If you connect to your server s public IP, you will see a screen similar to Figure 27. You might have to start an xterm from the background menu of twm. You can now start SWPM (sapinst) from the xterm. Figure 27. Connecting to the server s IP 30 Copyright IBM Corp. 2017. All rights reserved. without prior written permission of IBM.

Installing SAP software After downloading the installation media, follow the standard SAP installation procedure documented in the SAP installation guide for your SAP version and components, and the corresponding SAP notes. You can start SAP SWPM from the xterm, and execute the installation steps. Figure 28 shows the SAP SWPM for a standard installation. Figure 28. SAP SWPM Figure 29 provides the steps for a three-tier setup. Begin by selecting Distributed System and execute the first two steps in the list shown in Figure 29 on the database server. The third step can be executed on the application server(s). Make sure that you use the private addresses for the ASCS and the database hostnames during installation of the application servers. This will assure that network traffic between the application server and ASCS, or database, will path through the private network and not through the public network. Copyright IBM Corp. 2017.
