Cisco Global Site Selector Administration Guide

OL-10410-01

Chapter 2      Managing the GSS from the CLI

Replacing GSS Devices in Your GSS Network

10.

Save your configuration changes to memory by entering the following 
command:

gssm1.example.com# 

copy running-config startup-config

11.

Configure the GSS device as the replacement primary GSSM in the GSS 
network by entering the following command:

gssm1.example.com# 

gss enable gssm-primary

Note

After entering the 

gssm primary-to-standby 

command, you should 

ensure that at least 1 minute passes before you enter the 

gssm 

standby-to-primary

 command in order to allow time for proper GSS 

device synchronization.

Configuration changes do not take effect immediately. It may take up to 10 
minutes before the other GSS devices in the network learn about the new 
primary GSSM.

12.

Determine if you have a full backup of the interim primary GSSM database 
that you can restore on the new primary GSSM as follows:

  •

If yes, restore the interim primary GSSM database. See the 

“Restoring a 

Primary GSSM Backup”

 section in 

Chapter 7, 

, 

Backing Up, Restoring, and 

Downgrading the GSSM Database

. You can now use the replacement primary 

GSSM in your GSS network.

  •

If no, determine if you have a backup of the original primary GSSM database 
as follows:

  –

If yes, restore the original primary GSSM database. See the 

“Restoring a 

Primary GSSM Backup”

 section in 

Chapter 7, 

, 

Backing Up, Restoring, 

and Downgrading the GSSM Database

. Verify the existing global server 

load-balancing configuration settings (DNS rules and keepalives) and 
modify the settings as described in the 

Cisco Global Server 

Load-Balancing Configuration Guide 

(GUI-based or CLI-based 

version)

. 

You can now use the replacement primary GSSM in your GSS 

network.

  –

If no, proceed to Step 13.

13.

If you do not have a backup of either the interim or original primary GSSM 
database, do the following:
