3.3.1.2 AIX Configuration

During boot time, the configuration manager of AIX configures all the device drivers needed to have the SSA disks available for usage. The configuration manager can’t do this configuration if the SSA Subsystem is not properly connected or if the SSA Software is not installed. If the SSA Software is not already installed, the configuration manager will tell you the missing filesets. You can either install the missing filesets with smit, or call the configuration manager with the -i flag.

The configuration manager configures the following devices:

•SSA Adapter Router

•SSA Adapter

•SSA Disks

Adapter Router

The adapter Router (ssar) is only a conceptual configuration aid and is always in a “Defined” state. It cannot be made “Available.” You can list the ssar with the following command:

#lsdev -C grep ssar
