Use this procedure to destroy or delete a trunk. You destroy a trunk when you cease
needing it or want to use the interfaces for other purposes than a trunk. After you
complete this procedure, the interfaces in the trunk act individually rather than as links
in a trunk.

Data ONTAP 5.3 provides database file protection through the nvfail option of the
vol options command. The nvfail option enables a filer to detect NVRAM incon-
sistencies at boot time. Use it to warn database administrators of NVRAM problems
that could compromise database validity. If the filer finds any problems, database
instances hang or shut down, and the filer sends error messages to the console to
alert you to check the state of the database.

You can provide additional protection to specific database files by adding them to an
optional file you create called /etc/nvfail_rename. When you enable nvfail and
the filer detects NVRAM errors at boot up, the filer renames any database files speci-
fied in the nvfail_rename file by appending .nvfail to the original file name.
When the filer renames a database file, the database cannot restart automatically.
This gives you the opportunity to examine the file for inconsistencies before you
remove the .nvfail extension and make the file accessible again.

When you enable nvfail, the following process shown in Table 4-8 takes place
during boot-up.
