Configuring Security Group High Availability in Maestro

Note - Do not confuse this section with Configuring Weights for Security Group Members in Maestro that is related to traffic distribution inside a Security Group.

Setting Security Group Weights (High Availability Factors)

Each hardware component in a Security Group Member has a quality weight factor, which sets its relative importance to overall Security Group health.

For example, ports are more important than other components and are typically assigned a higher weight value.

The Security Group Member grade is the sum of all component weight values.

In a Dual Site environment, the Security Group with the higher grade becomes Active and handles traffic.

The grade for each component is calculated based on this formula:

(Unit Weight) x (Number of components in the state "UP")

To see the weight of each component, run in Gaia gClish on a Security Group:

asg stat -v

Description

Use the "set cluster configuration high-availability factors" command to configure a hardware component's weight.

Syntax in Gaia gClish of the Security Group

set cluster configuration high-availability factors member <Security Group Factor>

set cluster configuration high-availability factor {other <Other Port Factor> | standard <Standard Port Factor> | mgmt <Management Port Factor> | bond <Bond Port Factor>}

Examples

[Global] HostName-ch01-01 > set cluster configuration high-availability factors sgm 100

[Global] HostName-ch01-01 > set cluster configuration high-availability factors port other 70

[Global] HostName-ch01-01 > set cluster configuration high-availability factors port standard 50

Setting the Quality Grade Differential

Description

Use the "set cluster configuration high-availability failover" command in Gaia gClish to configure the minimum quality grade differential that causes a failover.

Syntax in Gaia gClish of the Security Group

set cluster configuration high-availability failover <Trigger>

Parameters

Parameter

Description

<Trigger>

Minimum difference in the Security Group quality grade to trigger a failover.

Valid values: 1 - 1000.
