Storage Manager The complete logical device address is composed of the following fields: HBA Bus Device LUN The controller to which the device is attached. PCI bus slots are scanned from lowest to highest looking for Adaptec controllers. As Adaptec controllers are found, they are assigned numbers incrementally, starting with 0. Channel number of the channel to which the device is attached. The unique ID for that device. For an array this is the lowest ID among the drives that make up the array. The LUN for that device is normally 0. Array groups are automatically assigned an address that corresponds to the lowest logical device address used by a device in that array group. When an array group has been created, its logical device address does not change if the drive with the lowest ID is replaced by a hot spare. When a hot spare replacement occurs, the failed drive automatically becomes the new hot spare. If you choose not to use that drive as a hot spare, Storage Manager prompts you to select an unused logical device address for that drive. Example If the lowest member device address for an array is HBA:0 Bus:1 ID:12 LUN:0, the LSU address is HBA:0 Bus:1 ID:12 LUN:0. 3-11

Storage Manager
The complete logical device address is composed of the following
fields:
Array groups are automatically assigned an address that
corresponds to the lowest logical device address used by a device
in that array group.
When an array group has been created, its logical device address
does not change if the drive with the lowest ID is replaced by a hot
spare. When a hot spare replacement occurs, the failed drive
automatically becomes the new hot spare. If you choose not to use
that drive as a hot spare, Storage Manager prompts you to select an
unused logical device address for that drive.
Example
If the lowest member device address for an array is HBA:0 Bus:1
ID:12 LUN:0, the LSU address is HBA:0 Bus:1 ID:12 LUN:0.
HBA
The controller to which the device is attached. PCI bus slots
are scanned from lowest to highest looking for Adaptec
controllers. As Adaptec controllers are found, they are
assigned numbers incrementally, starting with 0.
Bus
Channel number of the channel to which the device is
attached.
Device
The unique ID for that device. For an array this is the
lowest ID among the drives that make up the array.
LUN
The LUN
for that device is normally 0.
