Note: Refreshed Thin Image must be used with a Batch mover on the data flow.
The replication is created as a single, differential, in-system snapshot using Thin Image. The snapshot is refreshed on each batch resync rather than creating a new snapshot for each resync.

When an RTI data flow is deactivated, the refreshed snapshot is deleted.

Figure. Replicate Configuration Wizard - Refreshed Snapshot (Thin Image) - Configure Pool etc.
Control Description
Snapshot Pool Specifies the target storage pool from one of the following options to which replication LDEVs are allocated.
  • Match Source Pool – Allocates the snapshot in the same pool as the source volumes.
  • User Selected – Select a Thin Image Pool or a Dynamic Provisioning Pool.
Note: Thin Image Advanced Snapshots which are RoW snapshots will match source pool.
Provides a list of available pools giving name and available space.
Note: All replication types have pool except Asynchronous Remote Failover (Universal Replicator).
Note: Thin Image and Dynamic Provisioning Pools must be created using Storage Navigator prior to selecting the Target Storage/Pool in Protector.
Cascade Mode

The snapshot can be cascaded. This allows Protector to mount either the original snapshot or a duplicate of the original. Mounting a duplicate enables modifications to be made without affecting the original snapshot.

Refer to About cascaded Thin Image and Thin Image Advanced snapshots for further guidance on configuring and mounting cascade mode snapshots.
Use Consistency Group All P-VOLs in a replication are, by default, placed in the same consistency group to ensure consistency of data across all volumes. This option allows this behavior to be disabled.

Figure. Replicate Configuration Wizard - Configure Resource Group
Control Description
Configure Resource Group Specifies the resource group to be used for S-VOLs, in order to support snapshots and replications from VSM volumes (adding volumes to a VSM is performed by adding the volumes to the correct resource group).
Note: If there are existing S-VOLs, then the resource group used by those will be selected. If the existing S-VOLs are in multiple resource groups or in a resource group that contradicts the user selection, then the operation will fail with an error. This setting should not be modified for existing replications.
  • Automatically Selected - Allows Protector to automatically select a resource group in the following order of priority:
    1. If there are existing S-VOLs, then the resource group used by those will be selected.
    2. The resource group used by the P-VOLs, if the replication is in-system and the P-VOLs are all in one resource group.
    3. Resource group 0.
    Note: If existing S-VOLs are in multiple resource groups, then the operation will fail with an error.
  • User Selected - The user specifies the Resource Group.

Figure. Replicate Configuration Wizard - Refreshed Snapshot (Thin Image) - Naming Options
Control Description
Secondary Logical Device Name Specifies how S-VOLs will be named:
  • Match Origin - The S-VOL will be given the same name as that used for the origin P-VOL (i.e. the left-most volume in the data flow).
  • Custom - The S-VOL will be named using the naming rule provided. The naming rule can consist of literal strings and/or one or more substitution variables listed. Click Display variables which can be used for the secondary LDEVs' name to view the available substitution variables:
    • %ORIGIN_SERIAL% - S/N of leftmost array in data flow. E.g. output string: 210613
    • %ORIGIN_LDEV_ID% - ID of leftmost LDEV in data flow. E.g. output string: 00:3A:98
    • %ORIGIN_LDEV_NAME% - name of leftmost LDEV in data flow.
    • %PRIMARY_SERIAL% - S/N of primary array in this operation. E.g. output string: 442302
    • %PRIMARY_LDEV_ID% - ID of primary LDEV in this operation. E.g. output string: 00:4C:EB
    • %PRIMARY_LDEV_NAME% - name of primary LDEV in this operation.
    • %SECONDARY_SERIAL% - S/N of secondary array in this operation. E.g. output string: 356323
    • %SECONDARY_LDEV_ID% - ID of secondary LDEV in this operation. E.g. output string: 01:F4:35
    • %CREATION_DATE% - date secondary LDEV was created by this operation. E.g. output string: 20180427
    • %CREATION_TIME% - time secondary LDEV was created by this operation. 1130

Control Description
Snapshot Group Name Specifies how the snapshot group will be named.
  • Automatically Generated - The snapshot group name is generated by Protector based on the rules context ID and policy name.
  • Custom - The snapshot group is named using the string provided (limited to 28 characters). An '@' separator followed by a unique ID is then automatically appended to this name. The unique ID is composed of 3 base 36 characters and is required to enable Protector to manage the groups.
