SSA Location Code Format
Location codes identify the locations of adapters and devices in the using system
and their attached subsystems and devices. These codes are displayed when the
diagnostic programs isolate a problem. For information about the location codes that
are used by the using system, see the operator guide for the using system.

The location code shows only the position of the SSA adapter in the using system
and the type of device that is attached. Use a service aid to find the location of the
device (disk drive module). For more information, see “SSA Service Aids” on
