At a high level, deploying the Dell Red Hat Pacemaker solution consists of the following tasks:
Note: Adjust the IP addresses and security identifiers (SIDs) that are provided in this chapter for your environment. The values that are provided represent the minimum values required.
Dell SAP engineering used two networks in their test configuration:
The following table shows the hostnames that are used:
IP address | Hostname | Use |
10.14.20.10 | hana-ha | Cluster address of the SAP HANA cluster |
10.14.20.11 | hana01 | Host address of the first SAP HANA server |
10.14.20.12 | hana02 | Host address of the second SAP HANA server |
10.14.20.19 | nwascs-ha | Cluster address of the ASCS instance |
10.14.20.20 | nwers-ha | Cluster address of the ERS instance |
10.14.20.21 | nwacs01 | Host address of the first ASCS/ERS server |
10.14.20.22 | nwacs02 | Host address of the second ASCS/ERS server |
10.14.20.31 | nwwrk01 | Host address of the first application server |
10.14.20.32 | nwwrk02 | Host address of the second application server |
Important: The SID for the SAP HANA database must be different from the application layer SID; otherwise, the configuration fails on a later step. See SAP Note 2770989: Please choose a different SID for the SAP HANA database instance.
The following table shows the SIDs for the SAP NetWeaver instances that must be unique for the system to function properly:
SID | System number | Component |
TH0 | 00 | SAP HANA database |
TR1 | 00 | ASCS instance |
TR1 | 10 | ERS instance |
TR1 | 21 | Primary Application Servers |
TR1 | 22 | Additional application server |
Assign the shared disks for the servers that are running a cluster stack, as shown in the following table:
Function | Size | First host | Second host |
ASCS installation | >10 GB | nwacs01 | nwacs02 |
ERS installation | >10 GB | nwacs01 | nwacs02 |
Three shared file systems are required between all servers, as shown in the following table. An NFS server is strongly recommended.
Path | Size | Note |
/sapmnt | >10 GB | Required |
/usr/sap/TR1/SYS | >10 GB | Required (except on the hana01 or hana02 nodes) |
/sapinst | >50 GB | Optional for installation media |
The user IDs and group IDs shown in the following tables must be the same on all hosts. Review the user IDs and group IDs on all hosts in your SAP landscape before starting the deployment.
Username | ID | Role |
tr1adm | 1001 | SAP system administrator |
th0adm | 1002 | SAP HANA database administrator |
sapadm | 1003 | SAP system administrator |
Group name | ID | Notes |
sapinst | 1001 | N/A |
sapsys | 1002 | If this name is different between the hosts, the installation will fail. |
