Configuring FC I/O Blade
Channel Zoning
3
When FC I/O blades are installed in the library, administrative users can
configure channel zoning for selected I/O blades. Channel zoning, also
called port zoning, configures access to an entire FC 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 ports 1 and 2 and initiator ports 3–6 on an FC I/O blade.
Details on configuring channel zoning include:
• By default, all target FC ports (ports 1 and 2) on an FC I/O blade have
access to all initiator ports (ports 3–6).
• Changing channel zoning setting will cause the affected FC I/O blade
to reboot.
• If host port failover is enabled on the FC I/O blade, channel zoning
must be configured so that all target FC ports have access to all
initiator ports. For information on host port failover, see
Configuring
FC Host Port Failover
on page 113.
• The
Setup - Blade Channel Zoning
screen on the web client lists all FC
I/O blades found in the library. FC I/O blades are listed by the
following: location in the library, WWNN, and status. The
corresponding
Channel Zoning Select Blade
screen on the operator
panel lists the location in the library and state. You can select the I/O
blade you want to configure for channel zoning and proceed to the
next screen.
Note:
Channel zoning acts upon the FC tape drive LUNs seen
through the initiator ports on the I/O blade. Channel zoning
does not affect medium changer LUNs (partitions). If you
want to map hosts to medium changer LUNs though an FC
I/O blade, you must use the FC I/O blade’s FC host mapping
feature. For information on FC host mapping, see
Managing
FC Hosts and Host Mapping
on page 106.
Note:
If both channel zoning and host mapping are enabled, the
channel zoning settings supersede any host LUN mapping on
the I/O blade.
