THE SERVERS TAB

The Servers tab shows a table of all servers within the A.I.M. network.

Click the SERVERS tab to view the page.

For installations that require greater redundancy, it is possible to have two AIM servers

running on the same subnet. If the primary server fails then a secondary server with the

same database can take over until the primary unit recovers.

Each server entry will have one of four possible states within the Rôle column:

• Uncongured The server is a factory fresh device or has performed a full factory

reset. This does not yet have a proper role.

• Solo This is a server acting as a standalone A.I.M. All A.I.M. servers with rmware

below 3.0 will be in this state. If there is only going to be one A.I.M. on the subnet, this

is the Role that will be used.

• Primary The server is congured as a fully functional A.I.M. from which a back-up

server can be slaved.

• BackUp This server is congured to serve as a back up to the Primary.

Each server entry will also show one of six entries within the Status column:

• Active This server is functioning as an A.I.M. server and is administering ALIF devices.

Primary or Solo servers with this status are fully functional A.I.M. servers that will

accept network conguration changes. A backup server with this status is functioning

as an Active Primary. It will execute channel changes, but will not accept network

conguration changes.

• Standby This server is currently maintaining its database as a copy of the primary in

readiness to take over if necessary.

• Ofine This server should be maintaining a copy of the primary’s database, but is not

doing so.

• Initialising This is the initial status upon start up. This should not persist beyond the

initial start up procedure.

• Quiescent This is an inactive server on the network. It will not function without

remedial action from its system administration. A typical reason for this is the presence

of another server on the network blocking its congured role. i.e. two servers are

congured as a primary on the same subnet.

• Failed This server has suffered a serious internal failure.

Servers > Congure Server

When you click for a particular server, this page lists information about the unit and

allows several basic settings to be congured.

Rôle

Allows you to change the server’s function between primary and solo (see descriptions

left).

Device Name, Description and Location

These are useful identiers for the server unit and its exact location. These become even

more valuable as the number of servers within the system increases.
