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.

LUN The LUN for that device is normally 0.

Device The unique ID for that device. For an array this is the

lowest ID among the drives that make up the array.
