Case study: multi-SAN configuration
The recommendation for multi-SAN configurations is to install a single central. Domains can be
defined to display only subsets of the managed servers.

7.2.3. Prerequisites
Although backward compatibility is kept, it is recommended that all the AIX components of ASM be
at the same software level. If older components are already installed, it is mandatory to upgrade the
central server software for configurations where Windows NT servers are involved and to upgrade the
AIX local host agents for configurations where DAS4500 disk subsystems are added. As new software
versions usually include problem fixing, upgrading to the latest software is generally recommended
(note that upgrading does not modify the LUN access control).
For SAN configurations where the [e-mail]! V1 product is already used on Windows-NT servers, the
[e-mail]! configuration file of these servers only needs to be edited to modify the name of the central
server and the "[e-mail]! scheduler" NT service to be restarted for these platforms to be taken into
account by ASM. This does not modify the LUN access control configuration for these servers.
WebSM is a pre-requisite for the GUI.
AIX 4.3.2 and Java 1.1.6 are the minimum levels required for all the SAN Manager components on
AIX (GUI, central server and local host agent).
