Configuring a Unique IP Address per Site (UIPS) in Maestro Dual Site

In a Maestro Dual Site deployment:

  • A heavy load on the Active Site can prevent you from creating a network connection to the SMO and working with management tasks.

  • It can be necessary to have a direct access to the Standby Site to troubleshoot a problem, such as a Security Group Member in the DOWN state.

    You cannot use the SMO to connect to the Standby Site.

You can assign a unique IP address to each Standby Site to help resolve these issues.

This adds an alias IP address to the management interface that is assigned to the Security Group.

When there is a high load on the SMO, connect to the Standby Site using the unique IP address you assigned to the Standby Site.

The Security Group Members on the Standby Site are always in the state "UP" and available to run Gaia gClish commands.

Notes:

  • The UIPS feature is disabled by default in Maestro.

  • The UIPS feature does not support IPv6 addresses (Known Limitation MBS-9128).

  • The UIPS feature in Maestro supports only the management interface that is assigned to a Security Group.

  • Only one Security Group Member runs the "UIPS" task (similar to the "SMO" task).

    In the CLI output, this task appears as "UIPC" (the former name of this feature is "Unique IP Address per Chassis").

Description

Use the "set cluster configuration unique-ip ..." command in Gaia gClish to assign a unique IP address to a Standby Site.

Important - After you assign a unique IPv4 address to a Standby Site, you must make sure the Access Control policy of the Security Group allows the connection to the alias IP address.

Syntax

show cluster configuration unique-ip site-id <ID of Standby Site> interface <Name of Mgmt Interface>

set cluster configuration unique-ip <ID of Standby Site> interface <Name of Mgmt Interface> ipv4-address <IPv4 Address> mask-length <Length of Subnet Mask>

set cluster configuration unique-ip <ID of Standby Site> apply_unique_config

delete cluster configuration unique-ip site-id <ID of Standby Site> interface <Name of Mgmt Interface>

Parameters

Parameter

Description

<ID of Standby Site>

Specifies the ID of the Standby Site.

Valid values:

  • 1 - Site #1

  • 2 - Site #2

  • all - All Sites

<Name of Mgmt Interface>

Specifies the name of the Management Interface that is assigned to the Security Group.

For example, eth1-Mgmt1.

<IPv4 Address>

Specifies the alias IPv4 address on the same network as one of the Security Group Members' interfaces.

<Length of Subnet Mask>

Specifies the length of the IPv4 subnet mask.

Example 1 - Adding a UIPS

[Expert@HostName-ch0x-0x:0]# gclish
[Global] HostName-ch01-01 > set cluster configuration unique-ip 1 interface eth1-Mgmt4 ipv4-addess 172.16.6.186 mask-length 24>
1_01:
Adding Alias address 172.16.6.186 of eth1-Mgmt4
1_02:
Adding Alias address 172.16.6.186 of eth1-Mgmt4
2_01:
2_02:
Alias IP was added successfully to Site 1
Alias IP address should be added to the policy rulebase in SmartDashBoard
[Global] HostName-ch01-01 >

Example 2 - Deleting a UIPS

[Expert@HostName-ch0x-0x:0]# gclish
[Global] HostName-ch01-01 > delete cluster configuration unique-ip site-id 1 interface eth1-Mgmt4
1_01:
Deleting Alias IP 172.16.6.186 of eth1-Mgmt4
1_02:
Deleting Alias IP 172.16.6.186 of eth1-Mgmt4
2_01:
2_02:
Alias IP of Site 1 was deleted successfully
Alias IP address should be removed from the policy rulebase in SmartDashBoard
[Global] HostName-ch01-01 >
