Step 1B script

Creates all source VDISKs used in DR groups on this controller.

Step 1C script

Presents all source VDISKs (creates LUNS) that are used for DR groups to their
hosts. This step exists to assist in recovering from a DR failure in which a source
site was lost. LUNs can be presented in their original configuration by running the
correct step 1C script.

Step 2 script

Recreates all DR-specific configuration information for which this system is the
source. This involves the configuration's source DR_GROUPs and their members
only. Presentations of remote VDISKs are not restored by this command (see step
3).

This step provides flexibility when a site is completely lost. You must run step 1A,
step 1B, and step 1C on both source and destination systems before step 2 can be
run.

Note:

If no destination VDSIK is presented to a host, a blank script will be generated

for script 3.

Step 3 script

Presents remote VDISKs (creates LUNS) used for DR groups to their hosts.

You must run step 2 on both source and destination systems before step 3 can be
run.

Restoring configurations

To restore system configuration from captured scripts, you must run the following
scripts in the following order on each system that is part of the DR configuration.

Before running a captured configuration script, you need to modify an existing
script, run an additional script, or enter commands directly at the command line
setup, as in steps 1 and 2.
