At this point it is not necessary to reboot the machine until the configuration changes

have been made to the sd.conf and the lpfc.conf or lpfs.conf files.

5 Solaris Persistent Binding

Matching addresses with their associated devices requires that each Fibre Channel

director port be "bound" to a target number regardless of changes in the physical

locations of the Fibre Channel fabric. The Symmetrix fabric implementation uses a

method called "persistent binding," which is a map of target, driver instance, and

Symmetrix port. The Emulex HBA driver also implements the capability to bind

the devices by individual LUN (Symmetrix device).

Without a persistent binding mechanism, the host cannot maintain persistent logical

routing of the communication from a device address (/dev/rdsk/cNtNdNsN) across the

fabric to a Symmetrix volume. If the physical configuration of the switch is changed

(for example, the cable is swapped or the host is rebooted), the logical route becomes

inconsistent, causing possible data corruption if the user application is modifying data

through inconsistent logical routing of the communication from the driver entry point

(device address) to a volume in a Symmetrix across the fabric.
