CQUERY Output Example: M-VOL/Volume/Format
The following example shows the output of the CQUERY command issued to a TC390 R-VOL whose M-VOL
has been suspended by the CGROUP/RUN command. The pair status and path status at the RCU are not
changed.
CQUERY Output Example: R-VOL/Volume/Format
IEA494I and IEA491E Console Messages
When a TC390 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 window, 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 disk array and not
SIMs from the disk array. Therefore, SIMs reported by the disk array 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).
