When the filer boots, it uses the boot diskette in its diskette drive, if there is one.
Otherwise, the filer boots from its hard disk.

You should always execute the halt command before turning the filer Off for the fol-
lowing reasons:
The halt command flushes all data from NVRAM to disk, eliminating a potential
point of failure.
The halt command avoids potential data loss on CIFS clients.
If a CIFS client is disconnected from the filer, the users applications are termi-
nated and changes made to open files since the last save are lost.

Before turning the filer Off, use the halt or cifs terminate command to
send a warning message to CIFS users. This method gives users an opportunity
to save files and exit applications within the time period that you specified before
the actual shutdown.
NOTE: Clients using Windows 9x or Windows for Workgroups can display the
CIFS shutdown messages only when the clients WinPopup program is config-
ured to receive messages. The capability to display messages from the filer is
built into Windows NT.
