Explanation
The state of the PPRC pair has changed. In the
message text:
- dev
- The device number of the currently online PPRC pair.
Typically, this is the primary device of the PPRC, but if a Hyperswap
has occurred, it is the former PPRC secondary device. In some rare
cases, the IEA494I message is presented on both the primary and secondary
PPRC devices.
- volser
- The volume serial number of the primary device of a PPRC pair. Note that when a failure is received by an alias device
or an offline device, the volser is not available, so the message
text will not have the volser.
- state
- The new state of the PPRC pair is one of the following:
- SUSPENDING
- The control unit is in the process of suspending the PPRC pair.
This text appears only when the device is in the extended long busy
state, and EXTENDED LONG BUSY STATE will appear at the end
of the message.
- SUSPENDED
- The PPRC pair has changed from PENDING or FULL DUPLEX state
to SUSPENDED state. If the device in the extended long busy
state, the message will have the optional text EXTENDED LONG BUSY
STATE appended at the end.
- TERMINATED
- The PPRC pair has terminated from the PENDING, FULL DUPLEX,
or SUSPENDED state.
- PAIR PENDING
- A PPRC copy operation is starting. This might be initial or from
a previous suspended state.
- PAIR FULL DUPLEX
- A PPRC copy operation has completed and the primary and secondary
devices are synchronized.
- PPRC PAIR DUPLEX PENDING FC
- A PPRC pair is DUPLEX PENDING due to a FC which specified
a PPRC primary volume as a FLASHCOPY (FC) target.
- PPRC PAIR SUSPENDED FC
- A PPRC pair is SUSPENDED because of a FC that specified
a PPRC primary volume as a FLASHCOPY (FC) target and preserve mirror
required, and an error was encountered during the request.
- ssid
- The ssid of the primary device of the PPRC
pair.
- ca
- The two-byte channel connection address of the primary device
of the PPRC pair.
- ssid2
- The ssid of the secondary device of the PPRC pair. This identifies the
relationship that has changed. It is shown only if multi-target is supported and enabled.
- optional-text
- Is one or more of the following:
- EXTENDED LONG BUSY STATE.
- CONTINUATION OF IEA494I SNS=sense
In the
message text:
- sense
- Sense data.
- sense
- The 32 characters of sense data reported by the device.
xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx
Note: The optional text is present
only if the PPRC control unit microcode is at the correct level and
the Vital Product Data bit has been set at the control unit panel,
requesting activation of extended long busy mode. The duration of
this extended long busy is also set at the control unit panel, with
a default value of approximately two minutes. Contact your hardware
support group if assistance is required to set the bit and duration.
This message is broadcast to all subsystems where the device is attached and online.
Some systems may receive more than one variation of the SUSPENDED state message during a suspending
event.
System action
If no action is taken by the operator or automation
program , at the end of the EXTENDED LONG BUSY period, processing
will continue in suspended duplex state
Note: See
message IEA491E (IEA491E) for additional information
related to this message. Message IEA494I is detected and issued by
only one of the systems where the device is attached.
Operator response
This message is intended for use by automation
programs that monitor operator messages. Actions can be attempted
by the operator, but an automation program is recommended.
