Hi All,

Our IBM customer has recently migrated from A9000R to FlashSystem 9500.

Previously, they relied heavily on the volcopy feature for DR test preparation, using a Source → Target workflow.

Is there an equivalent way to achieve this using the newer snapshot functionality?
Any suggested workaround to replicate the same behaviour with current snapshot options?

Regards,
Shanker

Hi,

you can read IBM Redbooks publication "Ensuring Business Continuity: A Practical Guide to Policy-Based Replication and Policy-Based High Availability for IBM Storage Virtualize Systems". Chapter 2 contains details on how to recover and test your data on the target site.

The migration from A9000R to FlashSystem 9500 changes the replication and copy workflow because volcopy was specific to A9000/A9000R, while FlashSystem uses snapshot-based and replication-based mechanisms. 

FlashSystem does not have volcopy, but you can replicate the concept using:

FlashCopy (local copy)

This is the closest equivalent. It creates a point-in-time copy of a source volume to a target volume.

You can choose:

1. Snapshot mode (space-efficient, uses copy-on-write).
2. Full copy mode (background copy to make the target independent).
