Moving to McDATA Open Fabric mode from earlier Fabric OS versions
To move from interopmode 1 under Fabric OS 5.3 to Open Fabric mode:
1. Enter the switchDisable command to disable the switch.
switch:admin> switchdisable
2. Enter the interopmode 0 command (native Brocade mode).
3. Upgrade to Fabric OS 6.0.
4. Enter the interopmode 3 command to configure the switch to Open Fabric mode.
5. After the automatic reboot, after the automatic reboot, the switch will be online, establish ISL
connection(s) to Open Fabric mode.
Enabling McDATA Open Fabric mode
When configuring McDATA Open Fabric mode, avoid Domain ID conflicts before fabric reconfiguration.
When configuring multiple switches, you should wait for a fabric reconfiguration after adding or removing
each switch. Every switch in the fabric must have a unique Domain ID.
To enable McDATA Open Fabric mode:
1. Verify that you have implemented all the Brocade prerequisites necessary to enable interopmode 3
on the fabric (see ”McDATA Open Fabric mode configuration restrictions” on page 489.)
2. Connect to the switch and log in as admin.
Ensure that the switch is disabled or offline.
3. Enter the switchDisable command to disable the switch.
switch:admin> switchdisable
4. Enter the configure command to set the Domain ID to a number in the range from 97 to 127;
otherwise, the interopmode command will default you to 97. For detailed instructions, see ”Working
with domain IDs” on page 16.
switch:admin> configure
Configure...
Fabric Parameters (yes, y, no, n): [no] y
Domain (1...127): [1] 97
5. Enter the interopmode 3 command to enable interoperability. This command resets a number of
parameters and enables McDATA Open Fabric mode.
switch:admin> interopmode 3
McDATA Open Fabric mode is enabled
The switch effective configuration will be lost.
The system will reboot to allow the change to take effect.
Do you want to continue? (yes, y, no, n): [no]y
The configuration is being saved - a system reboot will
cause the change to take effect.
Please disable switch before changing the interop mode.
The switch automatically reboots after changing the interoperability mode.
6. Repeat step 2 through step 5 on each Brocade switch in the fabric. For more information on the switch,
refer to the switch documentation.
7. After enabling McDATA Open Fabric mode on all switches, physically connect the legacy McDATA
switches to the Brocade fabric, one at a time.
