Dell PowerVault DL2000 - Manual (Page 9)

About the DL Appliance configuration states and
configuration policies
The DL Appliance operates in one of two configuration states: standard or
advanced. Backup Exec automatically determines the configuration state by
checking the type, size, and configuration of the physical disks within the storage
enclosure. You select the configuration policy, which tells Backup Exec how to
manage newly-discovered physical disks.
The following table describes the configuration states:
Table 1-2 DL Appliance configuration states
Description Configuration state
Each storage enclosure that is attached to the DL Appliance
consists of logically-connected physical disks. Slots 1 through
7 contain a set of physical disks that are logically connected
to form one disk group. Slots 8 through 15 optionally contain
an additional set of physical disks that are logically connected
to form a second disk group. Slot 0 is used to reserve a physical
disk that is used as a hot spare for storage array fault tolerance
purposes.
When the DL Appliance is in the standard configuration state,
you can use one of two automatic configuration policies to
create virtual disks.
The policies include the following:
■ Automatic with confirmation
■ Automatic without confirmation
Table 1-3 describes the DL Appliance configuration policies.
Standard configuration
A DL Appliance that is configured in any manner that is not
standard.
With the DL Appliance in the advanced configuration state,
you can select only a manual configuration policy. This means
that all virtual disks must be manually created. You can use
the Dell™ OpenManage™ Server Administrator to manually
create virtual disks.
