Channel Zoning 4
Channel zoning, also called port zoning, is an optional feature that
configures access to an entire Fibre Channel and all the LUNs on that
channel for the exclusive use of a host or group of hosts on a single port.
Channel zoning enables you to control access between specific target
Fibre Channel (FC) ports and initiator channels on an I/O blade in your
library. If you make changes to the channel zoning settings, you must
reboot the I/O blade for the new settings to take effect.
If you change channel zoning after host
computers or applications have already
discovered devices, you must make sure that
device discovery occurs again. Device discovery
could occur automatically when you reboot the
library. Some host computers have plug and play
capability, which can discover devices
automatically. Host applications might discover
devices automatically.
