Halting the filer

Command to use

Use the halt command to perform an orderly shutdown by flushing file system updates to disk and cleaning the NVRAM.

Reasons to use the halt command

The filer stores requests it receives in nonvolatile random-access memory (NVRAM). For the following reasons, you should always execute the halt command before turning the filer off:

The halt command flushes all data from memory 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 terminated and changes made to open files since the last save are lost.

Caution
Never interrupt CIFS service by halting the filer without giving advance warning to CIFS users.

Note
Clients using Windows 95 or Windows for Workgroups can display the CIFS shutdown messages only when the clients' WinPopup program is configured to receive messages. The capability to display messages from the filer is built into Windows NT.
