HP P9000 Business Continuity Manager User Guide

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
Performing a local scan to acquire volume information
Perform a local scan at the primary site to acquire information about a storage system and
automatically create a disk configuration definition file. Initiate the local scan by either executing
the YKSCAN command or by initiating it from the ISPF panel.
To acquire storage system 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”
(page 102).
To see the procedures for initiating these operations from the ISPF panels, see “Acquiring volume
information” (page 430).
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
This section describes how to prepare for an NG scan to acquire device configuration information
of local Non Gen'ed volumes.
Preparing the hardware (NG Scan)
Table 26 (page 106) lists the prerequisite hardware and Table 27 (page 107) lists the storage system
settings for executing an NG scan.
