432 FICON fabrics
This serialization prevents interference from local switch commands when a host-based management
program is being used to administer the switch.
NOTE: You cannot use the portCfgPersistentEnable and portCfgPersistentDisable commands to
persistently enable and disable ports when FICON Management Server mode is on. See the procedure
”Persistently enabling and disabling ports” on page 435 for instructions.
Changing fmsmode from disabled to enabled triggers the following events:
• Access to switch parameters is serialized.
• The active CUP configuration data is established as follows:
• Port and switch names are not read from the IPL; they remain as previously set.
• Port Block and Unblock values are not read from the IPL; they remain as previously set with the
portEnable and portDisable commands.
• PDCM values are read from the IPL; the default is Allow All.
• Advanced Zoning, if used, continues to be in force. If there are any differences in restrictions set up with
Advanced Zoning and PDCM, the most restrictive rules are automatically applied.
• RSCNs are sent to devices if PDCM results in changes to connectivity between a set of ports.
Changing fmsmode from enabled to disabled triggers the following events:
• A device reset is performed on the control device.
• PDCM is no longer enforced.
• RSCNs might be generated to some devices if PDCM removal results in changes to connectivity
between a set of ports.
• If a given port was set to Block or Unblock, that port remains disabled or enabled.
• Serialized access to switch parameters ceases.
To enable fmsmode:
1. Connect to the switch and log in as admin.
2. Issue the command ficoncupset fmsmode enable.
To disable fmsmode:
1. Connect to the switch and log in as admin.
2. Issue the commandficoncupset fmsmode disable.
FMSmode and FICON CUP
When a CUP license is installed, the transition from fmsmode disabled to fmsmode enabled triggers
notification to the host systems that the CUP feature is available. Without this notification, the host systems
never know that the CUP feature is available and, consequently, never try to communicate with it.
If you install a CUP license on a switch that already has fmsmode enabled, you must disable fmsmode first
and reenable it after the license is installed so the host systems get the notification that CUP is enabled.
