Displaying FMS mode
Use the ficonCupShow fmsmode command to display the enabled or disabled state of FMS mode
for the switch.
Enabling FMS mode
Before enabling FMS mode, you must enable attributes for high-integrity fabrics and HIF mode. For
more information, refer to
Meeting high-integrity fabric requirements on page 33.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter ficonCupSet fmsmode enable.
3. Enter the ficonCupShow fmsmode command to verify that FMS mode is enabled.
Disabling FMS mode
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter ficonCupSet fmsmode disable.
3. Enter the ficonCupShow fmsmode command to verify that FMS mode is disabled.
Resetting FMS mode
Resetting FMS mode provides a method to fix unresponsive CUP conditions and other run-time errors.
CAUTION
Use this procedure only under direction from technical support personnel. Indiscriminate use
can disrupt CCW processing and create errors at the host.
Entering the ficonCupSet fmsmode reset command does not change any configuration states, but
accomplishes the following:
• Resets the Linux mutexes (SMCB, CFG, Asy CCW)
• Resets the CUP logical path allegiance to neutral
• Clears pending sense data
• Clears pending CUE accept-status state
• Clears pending CUE-Owed
The following example illustrates use of this command:
switch:admin>ficoncupset fmsmode reset
FMS_001(I) - FMSMODE RESET completed - FMSMODE(Enabled)
Conditions prior to reset:
All CUP states nominal, no conditions reset
FMS mode and FICON OxFE or OxFF ports
OxFE and OxFF addresses are assigned to the CUP and cannot be associated with any physical port
with FMS mode enabled. Therefore, note the following when using FMS mode:
