To add a failover group
1 To deploy standby nodes as backup, simply add multiple Network Security
nodes in the same location to form the failover group, considering the
following:
You can set up a failover group using both software and appliance
■
nodes interchangeably.
You can set up a failover group for either a master or a slave node.
■
Failover functions independently of master or slave status.
The active and standby node must both have the same physical and
■
logical configurations.
The active and standby node must monitor the same subnet.
■
The nodes must be installed in the same location.
■
Each node must have a dedicated physical connection for detection.
■
2 In the Network Security console, add or edit the active and standby objects
to the network topology tree, considering the following:
In Add or Edit 7100 Series Node, or Add or Edit Software Node, under
■
Failover Group Information, click Failover Group Member.
Enter a Failover Group Number between 1 and 100.
■
Each node within the failover group must have the same Failover
Group Numbers. Valid numbers range from 1 to 100. Do not use a
number over 100.
Click OK, and save the changes to the topology tree.
■
3 Set the following configuration parameters for each active and standby
node:
Setting Enable Watchdog Process
■
Setting Watchdog Process Stop Window
■
Setting Watchdog Process Maximum Resets
■
Setting Watchdog Process Restart Only
■
Setting Watchdog Process Email
■
4 Repeat these steps for each node in the failover group.
Note: SuperUsers can create watchdog groups; Administrators, StandardUsers,
and RestrictedUsers cannot. See
about permissions.
