Native Ficon Configuration On A Zseries Or S/390 Host; Ficon Mixed Channel Configuration - HP XP20000/XP24000 Operation Manual

Figure 21 FICON mixed channel configuration
.
In the example, one FICON bridge was removed from the configuration. The FICON channel that
was connected to that bridge is reconnected to the new FICON director using the storage unit FICON
adapter. The channel-path group was changed to include the new FICON path. The channel-path
group is now a mixed ESCON and FICON path group. I/O operations continue to the storage unit
across this mixed path group. Access to the storage unit devices is not interrupted because all the
actions are non-disruptive.
NOTE:
This configuration is supported for migration only.
Do not use this configuration for an extended period.
Migrate from a mixed channel-path group configuration to an all FICON channel-path group
configuration.

two FICON directors through a channel-path group to two FICON adapters. Note that the second
bridge has been removed and a FICON director has been added. The channel-path group has only
the FICON paths.
