SAP HANA high availability policy parameters

Enter the name of your SA MP domain.

Provide the name of an existing SA MP domain. The SA MP domain will host the SAP resources that will be configured with this template.

Enter the nodes where you want to automate SAP HANA.

These nodes must be listed by the SA MP command lsrpnode for the specified domain. You can use either the long or the short name for a node. An SA MP SAP HANA resource will be created for each of the specified nodes. The first node in list will be used as primary instance node. The node name is also used for the remoteHost parameter within the hdbnsutil command to enable System Replication for the secondary node.

List of values, value type for each value:

Hostname or IP version 4 address

Select the IP version used in the SAP environment.

Depending on the IP version, either a NetMask for IPv4 or a NetPrefix for IPv6 has to be specified.

IPv4

IPv6

This parameter will be ignored unless all following conditions are fulfilled:

Parameter # 3 has the value "IPv4"

Specify the IPv4 address that will be used as tiebreaker.

This IPv4 address is used to resolve cluster quorum in case of a cluster split.

Value type: IP version 4 address

This parameter will be ignored unless all following conditions are fulfilled:

Parameter # 3 has the value "IPv4"

Specify the virtual IPv4 address that clients will use to connect to SAP HANA.

This virtual IPv4 address is used to reach SAP HANA, independent of the system it is currently running on.

This parameter will be ignored unless all following conditions are fulfilled:

Parameter # 3 has the value "IPv6"

Specify the virtual IPv6 address that clients will use to connect to SAP HANA.

This virtual IPv6 address is used to reach SAP HANA, independent of the system it is currently running on.

Value type: IP version 6 address

This parameter will be ignored unless all following conditions are fulfilled:

Parameter # 3 has the value "IPv4"

Specify the netmask for the SAP HANA virtual IP address.

Enter the netmask for the subnet of the SAP HANA virtual IP address. An example for a netmask is "255.255.255.0".

This parameter will be ignored unless all following conditions are fulfilled:

Parameter # 3 has the value "IPv6"

Enter the NetPrefix for the SAP HANA virtual IP address. An example for a NetPrefix is 80.

Value type: Numeric Minimum value: 0, maximum value: 128

Enter the network interface for the SAP HANA IP address.(remaining part of description is harvested from running system)

The available network interface specifies to which network interfaces the SAP HANA virtual IP address can be bound, for AIX an example is en0, for Linux, an example is eth0. The same network interface name needs to be available on all nodes where the SAP HANA will be automated.

The SAP system ID consists of 3 characters and is configured during the SAP installation.

Specify your SAP instance owner user name.

The default SAP instance owner user's name is composed of the SAP SID (in lower case) and the suffix adm.

Enter your desired prefix for all SAP HANA resources.

This prefix will be used as a prefix for all SA MP resources that cover SAP HANA, for example SAP_HDB. For later operational tasks, the prefix can be used to start and stop resources with the same prefix with one single command. You may consider to encode the SAP solution name, e.g. PI, ECC or SCM, which would result in a prefix like PI_HDB.

Value type: String

This instance name identifies the SAP HANA instance on all cluster nodes. A sample instance name is HDB00.

Specify all site names of your SAP HANA nodes. (remaining part of description is harvested from running system)

The site names are used to enable System Replication for the SAP HANA instance. Use the same order as for the list of nodes. A sample site name is dcsite1.

List of values, value type for each value: String

Select the log replication mode for SAP HANA System Replication.

The SAP HANA log replication mode specifies how to send log information to the secondary instance. The modes synchronous (sync), synchronous in memory (syncmem) or asynchronous (async) can be set.
