IEA491E message
When a Continuous Access Synchronous Z pair is suspended due to a failure, the MCU reports
SCI as well as unit check status and sense bytes with F/M = FB. In response to the F/M=FB sense
bytes, the IEA491E system console message is generated (if supported by the host).
shows an example of an IEA491E message.
If the host supports GDPS and the FREEZE option is enabled, the IEA494I system console message
with extended long busy (which was generated in response to the SCI) triggers the CGROUP
(FREEZE/RUN) command.

P9500 response characteristics to failure conditions
The P9500 supports the CGROUP command in the GDPS environment by performing PPRC
compatible actions and returning PPRC compatible messages to failure conditions.
shows the failure conditions, and
describes the response characteristics
of the P9500 to these failure conditions.
The PPRC Support=Yes option must be selected on the RCU option dialog box. If not, the host
processor generates the system console message that includes the SIM instead of the IEA494I or
IEA491E message.
