Shutting down the node in a stand-alone system
For a node that is in a stand-alone configuration, you must perform a clean
shutdown to ensure that all data has been written to disk and disconnect the
power supplies.
Procedure
1.
Enter the following commands from the system console:
If your system is configured in...
Then issue this command...
7-Mode
halt
Clustered Data ONTAP
halt local
After you issue the command, wait until the system stops at the LOADER
prompt.
Attention:
You must perform a clean system shutdown before replacing
system components to avoid losing unwritten data in the nonvolatile memory
(NVMEM). The NVMEM LED is located on the controller module to the right
of the network ports, marked with a battery symbol. If the NVMEM LED is
flashing, there is content in the NVMEM that has not been saved to disk. You
need to reboot the controller module and proceed from the beginning of this
procedure. If repeated attempts to cleanly shut down the controller module fail,
be aware that you might lose any data that was not saved to disk.
