IEA494I and IEA491E Console Messages
When a TrueCopy for Mainframe pair is suspended, whether user-requested or due to failure, the
MCU generates sense information to notify the host(s). If the PPRC ERP PTF is installed and PPRC
Support = Yes is selected on the RCU option dialog box, this notification results in an IEA494I
system console message as well as an IEA491E message. The IEA491E message indicates the
reason for suspension. The IEA494I and IEA491E messages are generated by the zSeries and
S/390 host based upon SSBs (sense bytes) from the storage system and not SIMs from the storage
system. Therefore, SIMs reported by the storage system to the host are not used by the GDPS
scripting.
The IEA494I message is recommended as a trigger for automation over the IEA491E message.
The IEA491E message is reported to only one host system, whereas the IEA494I message is reported
to all attached MVS hosts each time the M-VOL pair status changes. GDPS uses the IEA494I
message with extended long busy as a trigger for CGROUP (FREEZE/RUN).
If PPRC Support = No is selected on the RCU Option dialog box, the host generates the system
console message that includes the SIM instead of the IEA494I or IEA491E message.
IEA494I Message
Whenever a TrueCopy for Mainframe pair status changes, with the exception of the TrueCopy for
Mainframe Asynchronous transition states suspending and deleting, the MCU reports
state-change-interrupt (SCI) to all hosts. In response to the SCI, the IEA494I system console message
is generated (if supported by the host). HP disk array reports SCI for both online and offline devices,
but the host system does not generate console messages for offline devices. Therefore, the IEA494I
