Setting up and dismantling a Secure Global Desktop array

You set up and dismantle an array of Secure Global Desktop servers:

• by using Array Manager; or
• by using the tarantella array command.

Note After making a change to the structure of an array, it is advisable to wait until Secure Global Desktop has copied the changes to all array members before making any further changes. The changes have been copied when the tarantella status command returns the same result for each array member.

Changing the structure of an array will have an effect on the certificates used for secure intra-array communication.

Adding a server to an array

In Array Manager, you add a Secure Global Desktop server to an array by clicking New Secondary and then typing the server's DNS name.

From the command line, you use the tarantella array join command.

If the server you add has been load balancing application servers using Advanced Load Management, we recommend that you do a warm restart (tarantella restart --warm) of the new server after it has joined the array. If the array to which the new server is joined is using Advanced Load Management, we recommend you do a warm restart of the whole array after the new server has joined.

Removing a server from an array

In Array Manager, you remove a Secure Global Desktop server from an array by right-clicking it in the tree and then clicking Detach Server.

From the command line, you use the tarantella array detach command.

To remove the primary server from an array, first make another server the primary server and then remove the old primary server.

When you remove a server from an array, it loses its license keys.

Changing the primary server in an array

In Array Manager, you change the primary server in the array by right-clicking the server you want to become the primary server and then clicking Make Primary.

From the command line, you use the tarantella array make_primary command.

Note The previous primary server becomes a secondary server.
