SNMP
SNMP, Simple Network Management Protocol, is the Internet's standard for remote monitoring and
management of hosts, routers and other nodes and devices on a network. Storage Mirroring provides
an SNMP sub-agent that monitors Storage Mirroring and can be managed from an SNMP Management
Console.
Storage Mirroring installs two components to work with SNMP.

The sub-agent is a program that installs and runs on the same machine as Storage Mirroring and
gathers statistics, data, and traps. The sub-agent forwards the information to the SNMP agent,
which relays the information to the manager. The Storage Mirroring SNMP sub-agent is included
in the Storage Mirroring installation program.

A Storage Mirroring .mib file is placed on the administrator’s machine so that the management
console can interpret the data sent from the sub-agent. The Storage Mirroring .mib file is dt.mib
and meets SNMP standards.
Configuring SNMP
The Storage Mirroring .mib file will need to be loaded into your SNMP Management Console.
Depending on the type of console you are using, this process might include compiling the .mib file.
Reference your SNMP Management Console documentation for additional information.
SNMP statistics
The following tables identify the Storage Mirroring statistics provided through SNMP.
NOTE: SNMP must be installed on a server before Storage Mirroring in order for the Storage
Mirroring SNMP components to be installed. If SNMP is installed on a server after Storage
Mirroring is installed, run a repair install to install the SNMP components.
