SBB Configuration
Part of the initial configuration procedure for the subsystem involves
configuring the disk drives so that the array controllers know the device
type, physical location, and logical location. This information is the basis
for the array controller transferring data blocks to specific disks to create
storage sets. Once the configuration process is complete, the system cannot
function properly unless all the disks remain in the same physical and
logical location.
The enclosure automatically notifies the array controller of the removal of a
device. This ensures that the array controller can implement the following
actions.
