Halting and rebooting the filer

The filer stores requests it receives in nonvolatile random-access memory (NVRAM). The use of NVRAM

The halt and reboot commands perform an orderly shutdown. During an orderly shutdown, the contents of NVRAM are flushed to disk.

To halt the filer, enter the following command:

halt

The filer displays the following prompt:

ok

Complete the following step to boot the filer.


Step	Action
1	Ensure that the `ok` prompt is displayed on the console.
2	Enter the following command: boot

You can halt and reboot the filer in a single operation by entering the following command:

reboot

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 following 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 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.

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 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.

For more information about cifs terminate, refer to "Stopping and restarting CIFS sessions."
