NOTE:
For configurations where the same storage system is connected from hosts at different
sites, the same volume might have different device numbers. Therefore, you cannot create a disk
configuration definition file on a site to transfer to the other sites for use. For this reason, perform
a local scan for P-VOLs and S-VOLs at each site, and then create a disk configuration definition
file.
Acquiring volume information (preparations)
To acquire device configuration information about the volumes on the storage systems, perform
the following scans:
•
Local scan
•
NG Scan on a local or remote site
•
Remote scan
CAUTION:
Do not perform a local scan on a storage system on which a remote scan was
performed. Likewise, do not perform a remote scan on a storage system on which a local scan
was performed.
Performing a local scan to acquire volume information
Perform a local scan at the primary site to acquire volume information about a storage system and
automatically create a disk configuration definition file. Perform the local scan from the ISPF panel
or by using YKBTSCAN (local scan) in batch.
To acquire volume information at the secondary site, perform a local scan at that site (using the
same file prefix you used for the local scan at the primary site), transfer the resulting disk
configuration definition file to the primary site and store the information in the disk configuration
definition file on the primary site.
For background information about the file prefix, see
“Setting a prefix for configuration files”
.
To see the procedures for initiating these operations from the ISPF panels, see
.
To see the procedures for using YKBTSCAN, see the HP Business Continuity Manager Reference
Guide.
HP recommends using YKBTSCAN to perform a local scan after you change a device address
(DEVN or VOLSER) that is stored on the host because YKBTSCAN updates the disk configuration
definition file with the latest information. After you change the device address (DEVN or VOLSER),
if you perform a local scan from the ISPF panel, copy pairs might not operate normally. To prevent
this, delete the existing disk configuration definition file, and then perform a local scan in the entire
range (including existing volumes).
NOTE:
In the operation in which the disk configuration definition file is periodically updated,
use YKBTSCAN if you want to perform a local scan in batch.
NOTE:
When performing a scan, Business Continuity Manager automatically determines the
model of the storage system and returns the information.

Performing an NG Scan (on a Non-Gen'ed Volume) to acquire device configuration
information
Perform an NG scan from the ISPF panel to acquire device configuration information about Non
Gen'ed volumes.
