Creating an instance (bastion stone server, active system, standby system)

Create an instance to be used in this environment. The creation process is the same for the bastion server (also used as a client), active nodes, and standby nodes, but some of the configuration values are different. Be careful to enter the appropriate values for the target instance.

1. Select ≡ > Compute > Instances.
   

2. Select sios20-c in the Compartment and click Create Instance.
   

3. Enter the following values in the form that appears and click Create.

*1 : An availability domain is one or more data centers located within a region. Since OCI still has many regions with a single availability domain, AD 1 is selected for both cluster nodes in this section. If multiple availability domains become available, specifying different availability domains for the active and standby nodes will increase availability.
*2 : A fault domain is a grouping of hardware and infrastructure, of which there are three within an availability domain. Instances can be distributed so that they do not reside on the same physical hardware within a single availability domain. To increase availability, specify different fault domains for active and standby systems.
*3 : Please select the OS version that your LifeKeeper deployment will support. For OS versions supported by LifeKeeper, please refer to each version’s support matrix (http://docs.us.sios.com/).
*4 : Specify a Shape for which the OS specified in Image can use. Depending on your tenancy, you may need to increase your service limits.

Editing/Creating VNICs

Make the following changes and additions to the VNICs used in both sios20-node1 and sios20-node2 cluster nodes.

• Change primary VNIC configuration
• Create a new secondary VNIC

The procedure is described using sios20-node1 as an example. After completing the change/addition of VNIC to sios20-node1, the same process should be performed for sios20-node2.

Change primary VNIC configuration

1. Select sios20-c under the Compartment and select sios20-node1 (or sios20-node2) in the list.
   

2. On the sios20-node1 (or sios20-node2) details page, click [︙] on the right side of the record under Attached VNICs > vnicyyyyyyMMddHHmmss (Primary VNIC) and select Edit VNIC. (yyyyyyMMddHHmmss is probably the creation time of the VNIC.)
   

3. Change and save the following configuration values. (Parameters for sios20-node2 are also listed)

Create a new secondary VNIC

1. On the sios20-node1 (or sios20-node2) details page, click Attached VNICs > Create VNIC.
   

2. Create two secondary VNICs, one for sios20-node1 and one for sios20-node2, by entering the following values in the form that appears.
