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
