An administrator may want to change a datastore setting configured within a VPG, such as a journal datastore, or a target datastore. This article explains the steps necessary to do so, so as to avoid any negative effects on replication.
Versions: 3.5 and greater
In order to change datastores configured within a VPG, consider
the points below:
- VM Recovery Datastore (‘Edit VPG’ screen, Replication tab, ‘advanced VM settings’ dialog)
- This value determines the datastore that will hold the recovery VM’s .vmx file, and the backing files of RDM recovery volumes.
- Should a cluster or a resource pool to be selected for a host, only datastores that are accessible by every ESX/ESXi host in the cluster or resource pool are displayed.
When specifying the recovery datastore for a virtual machine with a storage cluster, specify a specific datastore in the cluster.
- Datastore (‘Edit VPG’ screen, Replication tab)
- This value determines the target datastore used by default for VMs subsequently configured within the VPG and their volumes.
- Changing this value once VMs are already configured within a VPG will not affect the target datastore used for any of the already-protected VMs and their volumes.
- Recovery Volume Location (‘Edit VPG’ screen, Storage tab)
- This value determines the target datastore used for a specific volume configured within a protected VM.
- Changing this value for a VM already configured within a VPG, results in a storage vMotion for the relevant volume.
- Journal Datastore (‘Edit VPG’ screen, Replication tab, ‘Advanced Journal Settings’ dialog)
- This value determines the datastore used for journal data for each VM within the VPG
- The default value is the datastore used for recovery of each VM
