You can verify whether CIFS is running by using the cifs sessions command. If CIFS is not
running, a message is displayed, as shown in Example 16-7.

CIFS not running. Use "cifs restart" to restart
Use "cifs prefdc" to set preferred DCs
Use "cifs testdc" to test WINS and DCs

Halting the N series
You can use the command line or FilerView interface to stop the N series. You can use the
halt command on the CLI to perform a graceful shutdown. The -t option causes the system
to stop after the number of minutes that you specify (for example, halt -t 5 ). The halt
command stops all services and shuts down the system gracefully to the Common Firmware
Environment (CFE) prompt.
File system changes are written to disk, and the nonvolatile random access memory
(NVRAM) content is vacated.
Use the serial console because the IP connection is lost after halting the N series, as shown
in Example 16-8.

Booting the N series
As described in 16.2.1, “Starting the IBM System Storage N series storage system” on
page 217, the IBM System Storage N series storage systems automatically boots Data
ONTAP from a PC Compact Flash card. This card is included with the most current Data
ONTAP release. The Compact Flash card contains sufficient space for an upgrade kernel.
Use the
download
command to copy a boot kernel to the Compact Flash card.
The CFE prompt provides the following boot options:
򐂰 boot_ontap
Boots the current version of Data ONTAP from the Compact Flash card.
򐂰 boot_primary
Boots the current version of Data ONTAP from the Compact Flash card as the primary
kernel (the same kernel as boot_ontap).
򐂰 boot_backup
Boots the backup version of Data ONTAP from the Compact Flash card. The backup
release is created during the first software upgrade to preserve the kernel that is included
with the system. It provides a known good release from which you can boot the system if it
fails to automatically boot the primary image.
