NOTE: If PPRC Support = No is selected on the RCU Option window, the host generates the system
console message that includes the SIM instead of the IEA494I or IEA491E message.
IEA494I Message
Whenever a TC390 pair status changes, with the exception of the TC390A 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). The XP128/XP1024/XP10000/XP12000
reports SCI for both online and offline devices, but the host system does not generate console messages for
offline devices. Therefore, the IEA494I message is never generated with a TC390 R-VOL device address.
The following figure shows an example of an IEA494I message.
• The XP128/XP1024/XP10000/XP12000 MCU reports SCI for all TC390A pairs whose status has
changed, regardless of the Group/Volume option of the suspend or delete pair operation (if the status
change was user-requested).
• The XP128/XP1024/XP10000/XP12000 MCU reports SCI for all TC390 M-VOLs (synchronous only)
that are in the SCP state due to the CGROUP/FREEZE command. As shown in the following figure, this
IEA494I message indicates the extended long busy state.
• The XP128/XP1024/XP10000/XP12000 MCU reports SCI for all TC390 M-VOLs (synchronous only)
that are suspended due to the CGROUP/RUN command. This IEA494I message indicates the extended
long busy state.
• When the FREEZE option is enabled, the XP128/XP1024/XP10000/XP12000 MCU reports SCI for a
TC390 pair that is suspended due to a failure. When the host supports GDPS, this IEA494I message
with extended long busy triggers the CGROUP (FREEZE/RUN) command.
Output Example: IEA494I Message with Extended Long Busy State
IEA491E Message
When a TC390 pair is suspended due to a failure, the XP128/XP1024/XP10000/XP12000 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). The following figure shows an
example of an IEA491E message.
NOTE: 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.
Output Example: IEA491E Message
XP128/XP1024/XP10000/XP12000 Response Characteristics to Failure
Conditions
The XP128/XP1024/XP10000/XP12000 supports the CGROUP command in the GDPS environment by
performing PPRC-compatible actions and returning PPRC-compatible messages to failure conditions. The
following figure shows the failure conditions and the following table describes the response characteristics
of the XP128/XP1024/XP10000/XP12000 to these failure conditions.
