Business Copy operations
Business Copy system configuration (page 135) illustrates a Business Copy configuration. The
Business Copy commands also support the functionality that links the system operation for the
purpose of volume backup among UNIX servers managed by the operating system. For detailed
information about the operational requirements and specifications for Business Copy, see the HP
XP P9000 Business Copy User Guide for your storage system.
Following is a list of sample Business Copy functions that can be executed using RAID Manager
commands:
•
Pair creation: Creates a new volume pair. Volume pairs can be created in units of volumes
or groups.
•
Pair splitting: Splits a volume pair and allows read and write access to the secondary volume.
•
Pair resynchronization: Resynchronizes a split volume pair based on the primary volume. The
primary volume remains accessible during resynchronization.
•
Pair resynchronization with restore option: Resynchronizes a split pair based on the secondary
volume (reverse resync). The primary volume is not accessible during resync with restore option.
•
Event waiting: Used for waiting for the completion of a volume pair creation or
resynchronization to check the pair status.
•
Pair status display and configuration confirmation: Displays the pair status and configuration
of the volume pairs; this can also be used for checking the completion of a pair creation or
pair resynchronization.
