Managing clusters
The changes that you make on the first cluster member that you log on to are propagated to all other
cluster members, letting them appear as one security gateway, with the same users, network entities,
rules, and all other properties.
After you have completed your changes to the cluster, verify that the changes were propagated to all
cluster members.
In this section, you can find information for:

Changing the cluster account password
When you create a cluster, a cluster account is automatically added to the cluster configuration for
strictly internal cluster management. This account is an administrator account with a randomly
generated 16-character password. As you add each cluster member, this account is propagated to each
additional cluster member. Although this is an administrator account, it is only for internal cluster
management; you should never log on using this account.
If you change the cluster password, you must log on to each cluster member and make the same
change. All cluster passwords must match.
Note: Only change the cluster account password when higher security requirements are needed.
