Oracle Cloud Infrastructure and Software Requirements

Before installing and configuring the Oracle Cloud Infrastructure Recovery Kit (RK for OCI), be sure that your environment meets the following requirements.

Oracle Cloud Infrastructure Compute Instance

• Must be a bare metal instance or virtual machine instance provided by OCI.
• The Command Line Interface (CLI) 3.55.0 or later provided by OCI is available on the instance used as a cluster node.
• The Instance Metadata Service (IMDSv1) provided by OCI is available on the instance used as a cluster node.

Oracle Cloud Infrastructure Command Line Interface (CLI)

In order for the RK for OCI to operate OCI, configure the CLI and permissions so that the SYSTEM account of the cluster node can execute the following commands. Please refer to the OCI documentation for the CLI and permission settings.

oci network vnic assign-private-ip --vnic-id <vnicid> --ip-address <ip>
oci network vnic unassign-private-ip --vnic-id <vnicid> --ip-address <ip>
oci network private-ip list --vnic-id <vnicid>
oci network vnic get --vnic-id <vnicid>
oci network private-ip list --subnet-id <subnetid>

*Note: SIOS recommends adding the following parameters to %LKROOT%\Etc\default\LifeKeeper after configuring the OCI CLI by a regular user, as it is not common to configure the OCI CLI using the SYSTEM account.

OCI_CLI_CONFIG_FILE=<USER HOME>\.oci\config
OCI_CLI_SUPPRESS_FILE_PERMISSIONS_WARNING=True

<ip> is the IP address protected by LifeKeeper.
<vnicid> is the OCID of the virtual network interface card (VNIC) to which the IP address is assigned.
<subnetid> is the OCID of the subnet to which the VNIC is related.

IP address to use

• IP v4
• A virtual IP, i.e. the same IP Address that is shared in multiple nodes.
• The private IP address to be protected by the LifeKeeper RK for OCI must be an IP address that can be assigned to a VNIC.
  • It is the IP address in the subnet to which the VNIC to be assigned is related.
  • It is not an IP address reserved by OCI.
  • The number of secondary private IP addresses available for assigning has not been exceeded.
