򐂰 netboot
Boots from a Data ONTAP version that is stored on a remote HTTP or TFTP server. The
netboot option enables you to boot an alternative kernel if the Compact Flash card
becomes damaged. You can upgrade the boot kernel for several devices from a single
server.
To enable
netboot
, you must configure networking for the IBM System Storage N series
storage system by using DHCP or static IP address. Place the boot image on a configured
server.
For more information about setting up netboot , see this website:
http://www.ibm.com/storage/support/nas/
You often boot the N series after you run the
halt
command with the
boot_ontap
or
bye
command. These commands end the CFE prompt and restart the N series, as shown in
Example 16-9.
