this association, so you do not want it to change. The issue of SCSI ID assignment is addressed by
persistent binding.
Persistent binding is an HBA function that allows a subset of discovered targets to be bound between a
server and device. Implemented by a worldwide node name (WWNN) or worldwide port name (WWPN),
persistent binding causes a tape drive's WWNN to be bound to a specific SCSI target ID. After a
configuration is set, it survives restarts and any hardware configuration changes because the information
is preserved. If a drive must be replaced, the new drive assumes the WWNN of the old drive because the
WWNN for the drive is location-dependent within the library. Because the WWNN does not change,
persistent binding does not need changing, thus preventing a potential outage.
