Dell Solutions Enabler 10.0.0 TimeFinder/Clone CLI User Guide

Description

Data begins copying in the background when the clone session is activated and a full copy will become available to the host. While background copying, the state of the device pair is CopyInProgress. When the operation completes, the state goes to Copied. However, once the session is activated, the data is available immediately to the target host.

Examples

To create a clone copy session between source device and target device in group ProdDB, enter:

symclone -g ProdDB create

Rules and restrictions

The following rules and restrictions apply to a clone copy:

• The target device is made Not Ready to its host and placed on hold status for clone copy session activity. This prevents other control operations from using the device.
• The device pair state transitions from CreateInProgress to Created when complete.
• The clone copy does not become accessible to its host until the copy session is activated. Activate a TimeFinder clone copy session contains greater detail.
• A device pair cannot be verified that it is in the CreateInProgress state. After the copy session completes, issue a symclone verify -created command to verify that the clone pair is successfully created.
• If a copy session is created and not activated, it can be terminated. However, the data on the target device should be considered invalid.
