snmp contact ’jdoe@abc.com 555-555-1212’

filer. You can include the persons full name, but an email address and a tele-

receiving an automatic email message.

the recipient of all SNMP traps from the filer.

appropriate, to any trap hosts that were previously registered using the
snmp

The Dell custom MIB provides detailed information about many aspects of filer opera-
tion. You must use Dell custom MIB 1.1.2 or higher. It contains objects that help you
manage multivolume features.
Where to get the MIB: You can obtain the custom MIB from the Data ONTAP 5.3 CD.
To locate the MIB on the CD, read the
contents.txt
file.
Installing the MIB: Install the MIB file on your network management workstation
according to the installation procedure for your workstation, so that your workstation
can obtain information from the filer about the objects that are part of the MIB.
Using deprecated single-volume objects:
Single-volume objects
are
deprecated
,
but you can use them for single-volume systems as before. If you are using a single-
volume filer, you do not need to make changes to use the new MIB.
Finding multivolume objects: The descriptions of the deprecated single-volume
objects contain the names of the corresponding new
multivolume objects
. For
multivolume objects, use the new objects rather than the deprecated ones.
