Shutting down the node in a stand-alone system
For a node that is not configured with a high-availability (HA) partner, you must
perform a clean shutdown (ensuring that all data has been written to disk) and
disconnect the power supplies.
Procedure
1.
Enter the following command from the system console:
If your system is configured in...
Then issue this command...
7-Mode
halt
Cluster-Mode
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 NVRAM. The
NVRAM adapter has a red LED that blinks if there is unwritten data in the
NVRAM. If this LED is flashing red after you enter the
halt local
command,
reboot your system and try halting it again.
