HP StorageWorks P9000 Replication Manager Software 7.1 CLI User Guide (TB584-96026, May 2011)

Dictionary map files consists of the follow three types of map files and a backup
catalog:
- Application map file
- Core map file
- Copy group map file
- Backup catalog
disk group With VxVM, one or more logical devices can be grouped as individual units.
Disk groups can consist of one or more volumes, regardless of the content of the
logical volumes that comprise the disk group.
In a Veritas Volume Manager for Windows environment, a configured disk group
is recognized as one or more disk sets, and is handled as a minimum unit when
backing up or restoring data.
disk set For Application Agent in a dynamic disk configuration, a disk set is a group
consisting of one or more dynamic disks and one or more logical volumes
allocated to the dynamic disks.
dynamic disk The dynamic disk functionality is used to create a disk group by using VxVM.
Note, however, that the physical disks that make up a disk group or disk set are
sometimes called dynamic disks. You can join multiple dynamic disks to create
a logical volume (dynamic volume) or split a dynamic disk into multiple logical
volumes.
dynamic volume A logical volume created by joining or splitting one or more dynamic disks and
then assigning them.
Exchange
database
A generic name for storage groups and information stores.
failover The action of automatically switching to a backup system when an error occurs
in a system that has been duplicated (that is, multiple instances of the system
were made) using cluster software.
freezing a
database
DBMS temporarily stops I/O operations for the disk on which the database is
stored. Transactions from applications are controlled by DBMS until the database
is thawed.
If a database is frozen when a paired volume is synchronized, the primary and
secondary volumes will be identical. Backing up the database in this state will
ensure that its integrity is maintained during backup processing.
Hitachi Protection
Manager
The predecessor product of Application Agent.
Information Store A database that is used in Exchange Server. There are two types of Information
Stores: Mailbox Stores and Public Folder Stores. Mailbox Stores hold received
email messages, attached files, folders, and documents. Public Folder Stores
hold information, such as messages and documents, that can be shared by
multiple users.
metadata Data consisting of information about other data: such as the configuration and
attributes of a file system.
pair volume A pair of physical volumes that are mirror-controlled by RAID Manager and the
volume replication functions.
