AWS/Azure – Create LifeKeeper SAP Resources

*Note: This section applies to deployments on AWS and Microsoft Azure. For deployments on Google Cloud, follow the steps given in Google Cloud – Create LifeKeeper SAP Resources.

Create the ASCS Resource Hierarchy

1. In the LifeKeeper GUI, click the icon to open the Create Resource Wizard. Select the “SAP” Recovery Kit.

2. Enter the following values to create and extend a LifeKeeper resource (SAP-SPS_ASCS10) to protect the ASCS10 instance on node-a and node-b. Notice that the resource is being created on node-a and extended to node-b. Also note that the resulting resource should not be extended to node-c, the witness node. The icon indicates that the default option is chosen.

Field	Value
Create Resource Wizard
Switchback Type	intelligent
Server	node-a
SAP SID	SPS
SAP Instance for SPS	ASCS10
IP child resource	ip-sps-ascs
Automate dependent filesystem creation	no
Dependent filesystem resource	/usr/sap/SPS/ASCS10,nfs-/export/sapmnt/SPS
SAP Tag	SAP-SPS_ASCS10
Pre-Extend Wizard
Target Server	node-b
Switchback Type	intelligent
Template Priority	1
Target Priority	10
Extend gen/app Resource Hierarchy Wizard
Root Tag	SAP-SPS_ASCS10

Once the SAP-SPS_ASCS10 resource has been successfully created and extended to node-b, the LifeKeeper resource panel should look similar to the following.

3. Right-click on the SAP-SPS_ASCS10 resource and select Create Dependency… from the drop-down menu.

For Child Resource Tag, specify the nfs-/export/usr/sap/trans resource.

The resulting hierarchy will look similar to the following:

Create the ERS Resource Hierarchy

1. In the LifeKeeper GUI, click the icon to open the Create Resource Wizard. Select the “SAP” Recovery Kit.

2. Enter the following values to create and extend a LifeKeeper resource (SAP-SPS_ERS20) to protect the ERS20 instance on node-a and node-b. Notice that this resource is being created on node-b and extended to node-a. Also note that the resulting resource should not be extended to node-c, the witness node. The icon indicates that the default option is chosen.

Field	Value

Switchback Type	intelligent
Server	node-b
SAP SID	SPS
SAP Instance for SPS	ERS20
IP child resource	ip-sps-ers
Dependent filesystem resource	/usr/sap/SPS/ERS20
