This object is a user-assigned value used to assign individual
modules to a High-Availability Upgrade Group. All slots
within an upgrade group will be upgraded simultaneously.
The purpose of assigning multiple slots to the same upgrade
group is to reduce the overall time it takes to perform an
HA upgrade.
By default, each module is assigned to its own upgrade
group, with GroupId equal to the module's HAU Slot. Although
this default configuration is completely valid, it may not
be optimal for situations where a timely HA upgrade is
desirable.
The network architecture, specifically LAGs, must be taken
into consideration when assigning slots to an upgrade group.
LAGs which span multiple modules should not have all of their
modules placed into the same upgrade group, as this would
defeat the LAG's inherent redundancy.
IMPORTANT:
If a LAG is to remain available during a High-Availability
Upgrade, then it must comprised of multiple single-port links
which reside on separate modules. Furthermore, at least two
of those modules must reside in separate upgrade groups.
