HP XP Racks - Manual (Page 204)

This subsection explains the definition procedure in Business Continuity Manager. A delta resync
configuration is defined in the following procedure.
1.
Create a disk configuration definition file.
Create a disk configuration definition file by performing a Local Scan at each site, and then
transfer the file to the other sites.
2. Perform setup at the primary site.
At the primary site, create the necessary path set definition file and route list definition file,
establish a logical path, and register a command device.
3. Perform setup at the local site.
At the local site, create the necessary path set definition file and route list definition file,
establish a logical path, and register a command device.
4. Specify settings at the remote site.
At the remote site, create the necessary path set definition file and route list definition file,
establish a logical path, and register a command device.
5. Create copy groups.
At the primary site, define copy groups and make copy pairs.

Creating a Disk Configuration Definition File
Scan the storage system to create a disk configuration definition file. Perform a scan that includes
the volumes to be defined in the copy group and the command device. In a delta resync
configuration, because operations might be necessary at each site, you need to perform a scan
from each host, instead of a Remote Scan, to acquire the correct information, such as the device
number (DEVN).
To perform a scan from each host in a delta resync configuration to create a disk configuration
definition file:
1.
Perform a Local Scan at the primary site from the primary host.
2. Perform a Local Scan at the local site from the local host.
3. Perform a Local Scan at the remote site from the remote host.
