Introduction
UCS system has lots of components in it, i.e Blade server, Rack server, Fabric Extender,
Fabric Interconnect. All these are managed by the UCS manager. This document provides
the steps to gracefully shutdown and power up the UCS system.
Problem DescriptionIn an event when you need to shutdown the entire system for some activity follow the steps
mentioned below to gracefully shut the UCS system. It is recommended to backup the UCS
configuration before doing this activity as mentioned here. This document is applicable to
all hardware and software version of UCS. Note that the information in this document was
created from the devices in a specific lab environment. If your network is live, make sure that
you understand the potential impact of any command.
Solution
Follow the steps to gracefully shutdown UCS system:

Procedure to Gracefully Shutdown and Powerup UCS system

a) Graceful shutdown of servers: To shutdown the OS running in the server, UCSM sends
ACPI signal to the server OS. The OS generally responds by gracefully shutting down;
however this may not happen in certain cases. It is advisable to manually check if the OS
has shutdown. Disassociating service profile from the servers will also shutdown the severs;
however this is not advisable and is not graceful.
b) Disable management services: This step is optional and is intended only to
lower the admin burden because of UCS system going down. Disable services like
Smart call Home to stop UCS system from sending logs and information.
c) Decomission and Remove power to Chassis:Decomissoning is required only in case
if you need to change the chassis. In other cases you can directly remove the power tochassis. This is done to stop the power to blade/rack server and Fabric Extender. There is
nothing to be configured or saved from chassis end point.
d) Remove power to Secondary FI: This step is optional and is required only if you have
two FI in failover. Removing power first from secondary FI prevents the system from doing
failover, which is unnecessary here.
e) Remove power to Primary FI: As the last step remove the power to the primary FI. Note
that there is no graceful shutdown method in case of FI, since it is not required.
The UCS system is now properly down and you can proceed with the maintenance activity.
To bring the system back up follow the above steps in reverse order; i.e starting from the FI
and going up to the servers.
The UCS system should reboot without any issue. However after rebooting if you find that
the configuration is corrupt, follow the method to restore the configuration as described
here. If after rebooting the UCS system gets stuck in boot prompt then follow the method to
recover it as described here.
