Storage Manager
Logical Device Address
Every device and array is assigned a logical device address by Storage
Manager. This is the address used by the host operating system to access
the device or array. Logical device addresses appear in parentheses under
the logical device and LSU icons on the Logical Configuration View
window.
The logical device address is composed of four fields (HBA, Bus, Device,
LUN) and are assigned to devices as follows:
HBA (Host Bus Adapter)
The controller to which the device is attached. PCI bus slots are scanned
from lowest to highest looking for DPT controllers. As DPT controllers are
found they are assigned numbers incrementally, starting with 0.
Bus
The controller bus to which the device is attached. SmartRAID V
controllers can have up to three buses.
