Chapter 2: Installation tasks
NOTE:
If the switch is attached to a fabric element, the switch and
element must be set to the same E_D_TOV value. If the values are not
identical, the E_Port connection to the element segments and the
switch cannot communicate with the fabric. In addition, the
E_D_TOV value must be less than the R_A_TOV value.
c. Select from the Switch Priority drop-down list to set the switch
priority. Available selections are Default, Principal, and Never
Principal. The default setting is Default.
This value designates the fabric’s principal switch. The
principal switch is assigned a priority of 1 and controls the
allocation and distribution of domain IDs for all fabric
elements (including itself).
Principal is the highest priority setting, Default is the next
highest, and Never Principal is the lowest priority setting. The
setting Never Principal means the switch is incapable of
becoming a principal switch. If all switches are set to Principal
or Default, the switch with the highest priority and the lowest
world wide name (WWN) becomes the principal switch.
At least one switch in a fabric must be set as Principal or
Default. If all switches are set to Never Principal, all interswitch
links (ISLs) segment.
d. Select from the Interop Mode drop-down list to set the switch
operating mode. This setting only affects the mode used to
manage the switch; it does not affect port operation. Available
selections are:
• McDATA Fabric 1.0 - Select this option if the switch is
fabric-attached only to other IBM directors or switches
operating in McDATA fabric mode.
• Open Fabric 1.0 - Select this option for managing
heterogeneous fabrics and if the switch is fabric-attached to
IBM directors or switches and open-fabric compliant
switches produced by other original equipment
manufacturers (OEMs).This is the default.
NOTE:
When Open Fabric 1.0 is selected, the default zone is disabled
and you have to activate the default zone or enable the active zone
set.
