High Availability (HA)
Feature Description
8.1.2
HA Parameters
The role of the LoadMaster can be changed by setting the HA Mode. If the
HA Mode
is set
to
HA
(First) Mode
or
HA (Second) Mode
, a prompt will appear reminding to add a shared IP. Changing
the HA Mode will require a reboot, so after the details are set, click the
Reboot
button provided.
Once the LoadMaster has rebooted, the
HA Parameters
menu option will be available in the
System Configuration >
Miscellaneous Options
section provided the role is not
Non HA Mode
.
Configuring both units in the same
HA Mode
, i.e.
HA (First Mode)
and
HA (First) Mode
, will
result in severe operational problems as; not only will both units be master, both units will try to
use the same IP address.
When logging in to the HA cluster, use the shared IP address to view and set the full functionality
of the pair, apart from passwords and licensing. Logging in to the direct IP address of either one
of the devices displays different menu options (see menus below). Logging into one of the
LoadMasters directly is usually reserved for maintenance.
