CHAP properties
(Auto-Snapshot Manager) An ASM configuration option that enab
les you to specify CHAP credentials for VSS or
VDS access to groups and for computer access to Smart Copies for importing.
checksum verification
The process of verifying the integrity of Microsoft Exchange Smart Copies. Yo
u use the Windows eseutil.exe, a
database maintenance utility.
cloning
The process of creating a new copy of an object such a
s a volume. The new object is the same type and has the
same contents as the original. Contrast with a thin clone.
collection
(Auto-Snapshot Manager) Related groups of volumes or applica
tion components. These objects are represented by
nodes in the ASM Console Tree under the Collections master node. Create collections of related volumes that you
copy frequently. This ensures that ASM creates all the relevant Smart Copies simultaneously in one set. Create,
modify, or delete a collection, create a Smart Copy Set for the collection, or configure a schedule for the collection.
command generation
(Auto-Snapshot Manager) The
process of using the ASM GUI to generate an ASMCLI command.
console pane
(Auto-Snapshot Manager) The section of the ASM GUI that contains the console tree. This pane contains a
co
llapsing, branched structure of related groups of clickable objects on which you can perform many different
operations. See console tree.
console tree
(Auto-Snapshot Manager) A hierarchical structure of branch
ed nodes representing objects on which ASM can
perform operations. Nodes represent objects such as applications, volumes, and collections. The ASM console tree
consists of related groups of objects (nodes) organized in a branching tree structure. Depending on the status of a
node, you are presented with a menu of actions in the Actions Pane. See console pane.
control module
(hardware) The processor and interface component in a PS Series
array. A control module contains the PS Series
firmware in flash memory and provides temporary power continuity for data stored in cache memory. It has
multiple network interfaces and an optional serial port. An array can contain two hot-swappable, dual redundant
controllers. The active control module serves I/O, while the secondary control module mirrors data in its cache.
cooling module
(hardware) Hot-swappable hardware component, optionall
y integrated with a power supply, that provides cooling
to a PS Series array. Arrays are shipped with redundant cooling modules. An array can continue to operate if one
cooling module fails.
custom snapshot collection
(Auto-Snapshot Manager) One or more snapshots created at
the same time through a multi-volume snapshot
operation.
defer verification
(Auto-Snapshot Manager) When creating a replica, this operat
ion causes ASM to defer Checksum Verification and
Soft Recovery to a later time. Invoke the procedure manually or create a schedule at some future time.
delegated space
(Group Manager) Space on a group set aside to s
tore received replicas for a partner.
demote
(Group Manager) Convert a volume in a replication configuration
into a replica set.
