NOTE
You enable the fabric-wide consistency policy on the fabric once the switch joins the fabric.
NOTE
If FMS mode is enabled before upgrading to v7.3.0, IDID, SCC_Policy, and SCC:S will be
validated and the firmware attempt failed if either are incorrect. If validation is successful, HIF
mode will automatically enable when the firmware installs.
If a FICON channel tries to connect to a fabric switch without these features configured, the channel
segments from the fabric.
Once these features are configured, you must enable the switch in High-Integrity Fabric (HIF) mode
using the Fabric OS configure command. This verifies the required features are set and locks the
configuration to ensure connection with the FICON channel. Once the HIF mode is set, you cannot
change the IDID, fabric-wide consistency policy, and SCC policy without disabling HIF mode.
Following are considerations for using HIF mode:
•
You must enable HIF mode to enable FMS mode.
•
Before a Fabric OS downgrade, you must disable HIF mode. Note that this operation is not
recommended for FICON and should only be used when downgrading firmware. You will receive
a warning to this effect if FMS mode is enabled. If HIF is disabled, any new channel initialization
would fail as the Query Security Attribute (QSA) reply from the switch to the channel will fail. The
existing channel will continue to operate, however.
•
Before a Fabric OS upgrade, be sure the switch has appropriate IDID, fabric-wide consistency
policy, SCC policy settings are enabled so that HIF mode can enable when the firmware installs.
The following instructions are provided in this section to configure a switch as part of a high-integrity
fabric:

Enabling the insistent domain ID
To enable the insistent domain ID, complete the following steps for each switch in the fabric.
