Dell PowerVault DL2000 - Manual (Page 15)

Reboot the PowerVault DL2 x 00 and log on to resume the PowerVault DL Backup to Disk Appliance Configuration Wizard.
Configuring SNMP Settings
Simple Network Management Protocol (SNMP) is a network protocol used to manage TCP/IP networks. In Windows, the
SNMP service, known as the SNMP agent, provides status information about an SNMP host. You can add the appliance
to an SNMP community. In addition, you can add the name of other SNMP host(s) or an SNMP management system.
A community name acts as a password shared by one or more SNMP hosts. When adding additional host(s), the system
can accept either host names or an IP address.
An SNMP alert or SNMP trap is an event notification message sent by the SNMP trap service running on an SNMP host.
The SNMP trap is sent to other SNMP hosts or to an SNMP management system, which are known as trap destinations.
If SNMP alerts are required, one or more community names must be specified.
• Community name — The name of the community used by the trap destination. The SNMP agent can only send
SNMP trap messages to SNMP hosts that use a known community name.
• Trap Destination — Lists trap destinations, which are SNMP management systems that receive SNMP trap
messages from any SNMP host in the selected community.
Disk Configuration Settings
Disk Subsystem States
The appliance operates in one of the following configurations:
• Standard — In this state, the backup application automatically configures available disk drives in the
PowerVault DL2 x 00 system and optional storage enclosures and uses them for backup storage. You can set the
disk configuration policy to automatically configure the available disks by selecting either of the automatic
settings. See Disk Configuration Policies .
• Advanced — In this state, automatic disk configuration is disabled and the disk configuration policy
automatically switches to Manual. In this state, you must manually configure disk storage to be used by the
backup application.
The appliance determines the disk subsystem state by inspecting the storage subsystem. You cannot set the disk
subsystem state. The appliance disk subsystem state is standard if you use the predefined configurations for the DL2
x 00
system and any attached storage enclosures as shown in the following sections. If the predefined configurations are not
used, the disk subsystem state is advanced. Disk groups must include a drive in each of the indicated system and
storage enclosure slots except in the case when a failed drive has been temporarily removed for replacement.
Automatic disk configuration does not begin on a given disk group until every slot in the disk group is occupied by a disk.
The optional hot spares, if present, must reside in the indicated slot.
PowerVault DL2000 Disk Configurations
The PowerVault DL2000 supports SATA drives only. The operating system resides on a RAID 1 (mirrored) virtual disk
using slots 0 and 1. Slots 2 through 5 are not available for automatic configuration but can be manually configured (if
required).
