Introduces Volume Shadowing
for OpenVMS and describes how it provides high data availability.
|
Configuring Your System for High Data Availability
|
Illustrates various shadow
set configurations.
|
Preparing to Use Volume Shadowing
|
Describes how to set up
a volume shadowing environment, including information about setting
shadowing system parameters, booting a system that uses a system disk
in a shadow set, and booting satellite nodes from a shadowed system
disk.
|
Creating and Managing Shadow Sets Using DCL Commands
|
Describes how to use DCL
commands to create, mount, dismount, and dissolve shadow sets. The
chapter also describes how to use the SHOW DEVICES command, the

Ensuring Shadow Set Consistency
|
Describes how the copy and
merge operations maintain data consistency and availability during
changes in shadow set membership.
|
Using Minicopy for Backing Up Data (Alpha)

|
Describes how to perform
system management tasks on shadow sets, including performing backup
and upgrade operations, performing shadowing operations in OpenVMS
Cluster systems, and handling crash dumps on the shadow set.
