Installation guide

Configuration
Manual No. 771961 4-63
• Multi-TID—All ports are active. This topology is supported on all
Fibre products with ISP2200 hardware (FFx, MFF, etc.), and Firmware
v6.0 or above. This topology provides transparent failover/failback and
should not be used in conjunction with an alternate path driver.
(Required for FFx controllers!)
Topologies may be changed with some side effects:
• When changing from inactive port to master/slave, mapping logical
drives associated with controller 1 port 1 will be reassigned to
controller 0 port 1.
• When changing from master/slave to inactive port, port mapping
associated with controller 0 port 1 will be reassigned to controller 1
port 1.
• When changing from master/slave or inactive port to multi-TID or
MultiPort, the inactive ports will be enabled and all port mapping will
remain unchanged.
• When changing from multi-TID or multiPort to master/slave or
inactive, all mapping on the inactive ports will be lost.
Selecting the Port
Selection of the active port being configured is determined by the topology
selected. Inactive ports for the given topology are disabled and not available
for selection. The host to logical drive list and logical drive to LUN list are
displayed for the selected port.
Logical Drive to LUN Mapping
Logical Drive to LUN Mapping associates a logical drive defined in the
configuration with a LUN. The main list control displays the logical drive
(LD#, RAID level, and size), and LUN assignment. If no LUN is associated
with the logical drive, the LUN field is blank.
When a logical drive is selected, the LUN Selection field and the Enable All
Hosts check box become active. If a LUN assignment exists for the logical
drive, it is displayed in the LUN Selection field. If no assignment exists for
the logical drive, “None” is displayed. The LUN assignment drop-down box
displays all valid LUNs that may be assigned to the selected logical drive.
