1.
The QFabric system downloads, validates, and installs the new software in all
Interconnect devices and fabric control Routing Engines (FC-0 and FC-1).
2.
One fabric control Routing Engine reboots and comes back online.
3.
The other fabric control Routing Engine reboots and comes back online.
4.
The first Interconnect device reboots, comes back online, and resumes the forwarding
of traffic.
5.
Subsequent Interconnect devices reboot one at a time, come back online, and return
to service.
NOTE:
•
If the software does not load properly on any one of the fabric
components, all components revert back to the original software version.
•
If one of the components in a fabric upgrade does not reboot successfully,
issue the
request system reboot fabric
command to reattempt the
rebooting process for this fabric component and activate the new
software.
•
Node group—The third and final step upgrades Node groups. You can choose to upgrade
a network Node group, a redundant server Node group, or individual server Node groups.
You can upgrade the Node groups one at a time or in groups (known as upgrade groups).
However, you must upgrade all Node groups in your QFabric system before you can
complete the nonstop software upgrade process. To perform the third step, issue the
request system software nonstop-upgrade node-group
command.
The key actions that occur during a network Node group upgrade are:
1.
The QFabric system copies the new software to each Node device one at a time.
2.
The QFabric system validates and then installs the new software in all Node devices
simultaneously.
3.
The system copies the software to the network Node group Routing Engines.
4.
The QFabric system validates and then installs the software in the network Node
group Routing Engines one at a time -- first the backup, then the master.
5.
The backup network Node group Routing Engine reboots and comes back online.
6.
The supporting Node devices reboot and come back online one at a time.
NOTE:
To reduce the total upgrade duration, configure an upgrade
group. All Node devices within the upgrade group reboot at the same
time.
7.
The master network Node group Routing Engine relinquishes mastership to the
backup, reboots, and comes back online.
The key actions that occur during a redundant server Node group upgrade are:
