This wizard is displayed when you assign a replication operation to a Hitachi Block Device node on a data flow.
All replication and snapshot S-VOLs must be created using free LDEV IDs that are mapped to the meta_resource group, and have virtual LDEV IDs matching their corresponding physical LDEV IDs.
For fully provisioned snapshots and all replications, this applies to the operation that creates that snapshot or replication.
For floating device snapshots and snapshots mounted using cascade mode, this applies to the mount or restore operation.
For fully provisioned snapshots mounted using cascade mode, this applies both to the operation that creates that snapshot and to the mount or restore operation.
If an operation tries to create one or more LDEVs, that operation will fail if there are not enough free LDEV IDs that meet the above conditions.
- The classifications that are applicable to Hitachi Block Replication operations are File Path, Application, Hypervisor and Hitachi Block LDEV.
- Protector does not support any Hitachi Block storage LDEV with more than one partition or volume.
- If Protector is subsequently uninstalled, the existing replications and mounted volumes are left in place.
Once the operation properties have been configured and the data flow has been activated, the properties cannot be changed. Reactivating rules for the active data flow with edited properties will not change them.
To change the operation properties, the existing data flow must first be deactivated then reactivated with the new properties. Deactivating the data flow will tear down the current replication.
- The actions that are performed by hardware orchestration as it executes a block backup policy are captured by the Log Manager. Detailed logs and their attachments can be exported as a text file. (See Export Logs Dialog for more information.)
- Details of the hardware resources (LDEVs) used for a particular replication can be found in the Hitachi Block Device Details.
| Control | Description |
|---|---|
| Configure new replication | Creates a new replication defined by the user defined parameters. The Configure New Replication page of the wizard is displayed next. |
| Adopt existing replication | Adopts the replication defined by the user defined parameters from the matching pre-existing one on the hardware. The Adopt Existing Replication page of the wizard is displayed next. |
| Cancel | Discards all changes and reverts to the previous page. |
| Previous | Takes the user to the previous screen in the wizard. |
| Next | Takes the user to the next screen in the wizard. |
| Control | Description |
|---|---|
| Replication Type | Select the type of replication to create:
|
| Cancel | Discards all changes and reverts to the previous page. |
| Previous | Takes the user to the previous screen in the wizard. |
| Next | Takes the user to the next screen in the wizard. |
| Control | Description |
|---|---|
| Replication Type | Select the type of replication to adopt:
|
| Mirror Unit | Identify the mirror unit number of the replication to be adopted. Adoption requires at least one existing pair on the selected mirror unit. Note: If the mirror unit of an active replication is changed after initial data flow activation then:
|
| Copy Pace | Determines how quickly the storage array will be told to copy data for the adopted replication. The array’s default is Slow (3), Protector defaults to Medium (8). |
| Cancel | Discards all changes and reverts to the previous page. |
| Previous | Takes the user to the previous screen in the wizard. |
| Next | Takes the user to the next screen in the wizard. |
Shows a summary of the replication configuration specified by the user. All other parameters defining the replication are obtained from the hardware when the data flow is activated and triggered.
