Note: You can perform all steps from the DS CLI.
Perform the following steps to create a remote FlashCopy operation:
1. Create paths between the source LSS and the target LSS. For example,
IBM.2107-1300861 and IBM.2107-1300871. You need to know which volumes are
available for use before you can issue the request to establish the path.
2. Create Metro Mirror volume pairs from the source LSS to the target LSS. For
example, volume 2200 (IBM.2107-1300861/0001) from LSS22 and volume 2A00
(IBM.2107-1300871/0001) from LSS22.
3. Enable a Remote FlashCopy operation at the target site using volume B as
the source volume and volume C as the target volume. Assume that the target
site network connection is lost. You can create the FlashCopy relationship from
volume B to volume C (both volumes at the target site). However, you cannot
use the DS Storage Manager for this step because connections to the target site
are lost. You must use the DS CLI for this step (see Processing Remote
FlashCopy [inband] transactions in the IBM System Storage DS8000
Command-Line Interface User's Guide for additional information.
