This section describes how to deploy the Dell SUSE Pacemaker solution.
Note: Adjust the IP addresses and SIDs that are provided in this chapter for your environment. The values that are provided represent the minimum that you will need.
Dell SAP engineering used two networks in their test configuration:
IP address | Hostname | Usage |
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 |
10.14.19.11 |
| Second network, first HANA server |
10.14.19.12 |
| Second network, second HANA server |
10.14.19.21 |
| Second network, first ASCS/ERS server |
10.14.19.22 |
| Second network, second ASCS/ERS server |
Important: The security identifier (SID) for the SAP HANA database must be different from the application layer; otherwise, the configuration will fail on a later step. See SAP Note 2770989: Please choose a different SID for the SAP HANA database instance
The system numbers for the SAP NetWeaver instances must be unique for the system to function properly.
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 following shared disks for the servers that are running a cluster stack:
Function | Size | First host | Second host |
SBD device1 cluster 1 | >7 MB | hana01 | hana02 |
SBD device2 cluster 1 | >7 MB | hana01 | hana02 |
SBD device1 cluster 2 | >7 MB | nwacs01 | nwacs02 |
SBD device2 cluster 2 | >7 MB | nwacs01 | nwacs02 |
ASCS installation | >10 GB | nwacs01 | nwacs02 |
ERS installation | >10 GB | nwacs01 | nwacs02 |
Three shared file systems are required between all servers. An NFS server is strongly recommended.
Path | Size | Note |
/sapmnt | >10 GB | Required |
/usr/sap/TR1/SYS | >10 GB | Required (except on Hana01/02) |
/sapinst | >50 GB | Optional for installation media |
The following user IDs and group IDs must be the same on all hosts. Review the user IDs and group IDs on all hosts in the landscape.
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 |
|
sapsys | 1002 | If this name is different between the hosts, the installation will fail. |
