severity code

String of characters used to describe an event. The severity code indicates the relative impact the

event could have on network operations and the priority a network manager should place on

investigating the event. The following are common severity codes.

Fatal Critical Major

Minor Warning Information

Other Unknown

Each event is assigned a severity code and Management Appliance users can filter event

notifications to include only specified severity codes. See “Configuring User Properties for

Notification,” on page 68 for more information.

SMTP Server (for Management Appliance)

The outgoing mail server used by the Storage Management Appliance to send e-mail notification

to a standard e-mail address or an e-mail pager address. See “Setting Up the SMTP Server,” on

page 35 for more information.

SNMP Trap

Message or unsolicited response from an SNMP agent indicating the occurrence of a particular

event. The MIB module for each agent defines the trap messages the device can generate. The

Storage Management Appliance learns of an event when it receives a trap message from an SNMP

agent. The Management Appliance can decode SNMP traps from supported devices and generate

detailed notification messages or simply forward SNMP traps to another host. The Management

Appliance can generate SNMP traps that can be decoded by other devices using the Management

Appliance MIB module. See “Setting Up Notifications,” on page 71 for more information.

SNMP trap forwarding

A type of Storage Management Appliance notification that relays the SNMP trap message

received from a SAN component to any number of hosts. Each host is called a trap recipient and

must be identified by host name and IP address. See “Defining Network Settings,” on page 36 for

more information.

Storage Area Network (SAN)

A high-speed network that interconnects different kinds of storage elements with data servers on

behalf of a larger network of users, typically using Fibre Channel technology.

storage element

A storage system connected to a Storage Area Network (SAN) that is administered as a single unit.

A storage element usually has a single controller or controller pair operating to assure continuity of

service. A network administrator can use an element manager application to manage several

storage elements of the same type.
