Appendix A. Mapping File Attributes
The following table describes the attributes in the mapping file that is used to fail over and fail back between the two sites in an active-passive disaster recovery solution.
| Mapping File Section | Description |
|---|---|
| Site details | These attributes map the Manager details in the primary and secondary site. For example: dr_sites_primary_url: https://manager1.example.redhat.com/ovirt-engine/api dr_sites_primary_username: admin@internal dr_sites_primary_ca_file: /etc/pki/ovirt-engine/ca.pem # Please fill in the following properties for the secondary site: dr_sites_secondary_url: https://manager2.example.redhat.com/ovirt-engine/api dr_sites_secondary_username: admin@internal dr_sites_secondary_ca_file: /etc/pki/ovirt-engine/ca.pem |
| Storage domain details | These attributes map the storage domain details between the primary and secondary site. For example: dr_import_storages: - dr_domain_type: nfs dr_primary_name: DATA dr_master_domain: True dr_wipe_after_delete: False dr_backup: False dr_critical_space_action_blocker: 5 dr_warning_low_space: 10 dr_primary_dc_name: Default dr_discard_after_delete: False dr_primary_path: /storage/data dr_primary_address: 10.64.100.xxx # Fill in the empty properties related to the secondary site dr_secondary_dc_name: Default dr_secondary_path: /storage/data2 dr_secondary_address:10.64.90.xxx dr_secondary_name: DATA |
| Cluster details | These attributes map the cluster names between the primary and secondary site. For example: dr_cluster_mappings:
- primary_name: cluster_prod
secondary_name: cluster_recovery
- primary_name: fc_cluster
secondary_name: recovery_fc_cluster
|
| Affinity group details | These attributes map the affinity groups that virtual machines belong to. For example: dr_affinity_group_mappings: - primary_name: affinity_prod secondary_name: affinity_recovery |
| Affinity label details | These attributes map the affinity labels that virtual machines belong to. For example: dr_affinity_label_mappings: - primary_name: affinity_label_prod secondary_name: affinity_label_recovery |
| Domain AAA details | The domain Authentication, Authorization and Accounting (AAA) attributes map authorization details between the primary and secondary site. For example: dr_domain_mappings: - primary_name: internal-authz secondary_name: recovery-authz - primary_name: external-authz secondary_name: recovery2-authz |
| Role details |
The Role attributes provide mapping for specific roles. For example, if a virtual machine is registered with a user with a dr_role_mappings: - primary_name: VmCreator Secondary_name: NewVmCreator |
| Network details | The network attributes map the vNIC details between the primary and secondary site. For example: dr_network_mappings: - primary_network_name: ovirtmgmt primary_profile_name: ovirtmgmt primary_profile_id: 0000000a-000a-000a-000a-000000000398 # Fill in the correlated vnic profile properties in the secondary site for profile 'ovirtmgmt' secondary_network_name: ovirtmgmt secondary_profile_name: ovirtmgmt secondary_profile_id: 0000000a-000a-000a-000a-000000000410 If you have multiple networks or multiple data centers then you must use an empty network mapping in the mapping file to ensure that all entities register on the target during failover. For example: dr_network_mappings: # No mapping should be here |
| External LUN disk details | The external LUN attributes allow virtual machines to be registered with the appropriate external LUN disk after failover and failback. For example: dr_lun_mappings: - primary_logical_unit_id: 460014069b2be431c0fd46c4bdce29b66 primary_logical_unit_alias: Fedora_Disk primary_wipe_after_delete: False primary_shareable: False primary_logical_unit_description: 2b66 primary_storage_type: iscsi primary_logical_unit_address: 10.35.xx.xxx primary_logical_unit_port: 3260 primary_logical_unit_portal: 1 primary_logical_unit_target: iqn.2017-12.com.prod.example:444 secondary_storage_type: iscsi secondary_wipe_after_delete: False secondary_shareable: False secondary_logical_unit_id: 460014069b2be431c0fd46c4bdce29b66 secondary_logical_unit_address: 10.35.x.xxx secondary_logical_unit_port: 3260 secondary_logical_unit_portal: 1 secondary_logical_unit_target: iqn.2017-12.com.recovery.example:444 |
