• If mode 484 is ON, the status of path as using the Fibre Channel interface will be displayed. If mode
484 is OFF, ESCON will be indicated for the path status.
• If the former type subsystem or the subsystem of XP12000/XP10000 microcode version 50-05-XX-XX or
earlier is connected, mode 484 must be OFF.
Output Example: CQUERY
CGROUP (FREEZE/RUN) support
The TC390 feature supports the CGROUP (FREEZE/RUN) TSO command for PPRC, which is also used in
IBM’s Geographically Dispersed Parallel Sysplex (GDPS) environment. The CGROUP TSO command is
used to control I/O operations for TC390 Synchronous pairs on a specific MCU-RCU pair. The CGROUP
command is supported for the XP12000/XP10000 (and other XP disk arrays) functioning as TC390 MCUs.
The XP disk arrays provides all required host reporting for CGROUP operations (for example, IEA494I with
extended long busy (ELB) state), which is a key component of GDPS operations. For disaster recovery
implementations, you must use the XP12000/XP10000 at both sites because the RCUs will become MCUs
in the event of a disaster.
