Managing switches
In McDATA Fabric mode, the McDATA 4Gb SAN Switch will display the domain IDs the same as other
M-series directors and edge switches no matter which management utility is used. The valid domain ID
range is 1—31 for McDATA Fabric mode.
Prior to changing from McDATA Fabric mode to Standard mode, it is recommended that the switch be
isolated from the fabric (take switch offline) before making the configuration changes and all domain IDs in
the fabric should be noted to avoid conflicts. Once isolated, using CLI or McDATA Web Server, change
interop mode to Standard, and change the domain ID to a unique ID within the valid range of 97—127
for standard mode. It is then recommended that the Domain ID be locked to prevent conflict within the
fabric. When all changes have been made and the switch has been brought back online, it should then be
added into the fabric.
NOTE:
Locking the domain ID prevents the principal switch from assigning a domain ID when the switch
is added to the fabric. In a fabric where the principal switch is an M-series director or edge switch, this is
not an issue. In a fabric where the McDATA 4Gb SAN Switch may be the principal switch, changing from
McDATA Fabric mode to Standard mode without configuring the valid ID range and locking it, may result
in the switch domain ID being converted to a number not within the valid range.
lists the corresponding domain ID values for each interop mode: Standard mode and McDATA
Fabric mode.
Fabric Device Management Interface
Fabric Device Management Interface (FDMI) provides a means to gather and display device information
from the fabric, and allows FDMI capable devices to register certain information with the fabric, if FDMI is
enabled. McDATA Web Server will report any and all FDMI information reported by the entry switch, if
FDMI is enabled on the entry switch. To view FDMI data, FDMI must be enabled on the entry switch and on
all other switches in the fabric which are to report FDMI data.
FDMI is comprised of the fabric-to-device interface and the application-to-fabric interface. The
fabric-to-device interface enables a device’s management information to be registered. The
application-to-fabric interface provides the framework by which an application obtains device information
from the fabric. Use the FDMI HBA Entry Limit field on the Switch Properties dialog to configure the
maximum number of HBAs that can be registered with a switch. If the number of HBAs exceeds the
maximum number, the FDMI information for those HBAs can not be registered.
