Operational Reboot Commands
The following commands enable you to reboot the entire QFabric system, various Node
devices, or the QFabric system infrastructure:
• request system reboot all
This command reboots the Director group, fabric control Routing Engines, fabric
manager Routing Engine, Interconnect devices, and network and server Node groups.
• request system reboot director-group
This command reboots the Director group and the default partition, which is where
you access the QFabric system CLI.
• request system reboot fabric
This command reboots the fabric control Routing Engines and the Interconnect devices.
• request system reboot node-group
This command reboots a server Node group or a network node group.

Understanding Nonstop Software Upgrade for QFabric Systems
Supported Platforms
QFabric System
The framework that underlies a nonstop software upgrade in a QFabric system enables
you to upgrade the system in a step-by-step manner and minimize the impact to the
continuous operation of the system. This topic explains how a nonstop software upgrade
works in a QFabric system, the steps that are involved, and the procedures that you need
to implement to experience the benefits of this style of software upgrade.
Nonstop software upgrade enables some QFabric system components to continue
operating while similar components in the system are being upgraded. In general, the
QFabric system upgrades redundant components in stages so that some components
remain operational and continue forwarding traffic while their equivalent counterparts
upgrade to a new version of software.
TIP: Use the following guidelines to decide when to implement a nonstop
software upgrade:
•
If you need to upgrade all components of the system in the shortest amount
of time (approximately one hour) and you do not need to retain the
forwarding resiliency of the data plane, issue the
request system software
add component all command to perform a standard software upgrade. All
components of the QFabric system upgrade simultaneously and
expediently, but this type of upgrade does not provide resiliency or
switchover capabilities.
