7.3.6 Adding and removing server names (addserver/delserver)

You can use the addserver command to add an additional server name on a system, in order

to enable the clients to access the server with the newly added name.

You can use the delserver command to delete a server name that was added with the

addserver command. This disables the clients to establish a new connection to the server

using this server name.

Usually these commands are used in high availability configurations.

Syntax:

addserver <computername>

delserver <computername>

Example:

One of two servers (lion and tiger) fails (e.g. tiger). The system administrator enters the

following command on the lion system:

/var/opt/lanman/etc/addserver tiger

The connected clients have to re-establish the connection to the r esources to be used.

While the clients establish the connection under the name tiger, they use resources on the

lion server.

After the failed server is operational again, the command for deleting the alternative name

must be entered on the second server:

/var/opt/lanman/etc/delserver tiger

Exi sting connections to the server lion which were set up using the name tiger are

not terminated when the name is deleted.

Advanced Server for UNIX can then be started on the failed server and the clients ca n use

the resources on the tiger server again.

This example takes no note of any actions that may be necessary to ensure the

availability of resources and user data.
