IEA482I ser WAITING FOR CONTROL UNIT - dev, REASON CODE=(nn) SENSE=sense
Explanation
I/O was attempted to a DASD device whose control unit is in a long-busy condition. This busy condition might last for several minutes; the additional messages may describe the reason code for the long-busy condition and the appropriate Operator Response. Under normal recovery most of the reason codes listed below should only last for a short period of time. If a long-busy condition has recovered then no message is issued.
- ser
- Volume serial number.
- dev
- DASD device number.
- nn
- Reason Codes and additional message text are:
- Code
- Additional Message Text
- 00
- NO REASON CODE DEFINED
No further information is provided by the hardware.
- 01
- EMERGENCY DESTAGE IN PROGRESS
A possible hardware problem has occurred requiring an emergency destage of the data. Contact hardware support for further assistance.
- 02
- DIAGNOSTIC REINITIALIZATION
The control unit is performing a recovery function.
- 07
- COMMIT ORDER WAS RECEIVED
The control unit is currently committing all writes in cache to the drive(s).
- 0C
- CONCURRENT COPY SIDEFILE EXCEEDING LIMITS
The control unit is transferring data from cache to the hardware because the storage cache thresholds have been exceeded.
- 0D
- XRC SIDEFILE EXCEEDING LIMITS
The control unit is transferring data from cache to the hardware because the storage cache thresholds have been exceeded.
- 0E
- PPRC QUIESCE ORDER ISSUED TO THE DEVICE
The control unit is busy until the PPRC Pair has been terminated.
- 0F
- RESERVE ISSUED TO XRC UTILITY DEVICE
A reserve is issued to a XRC utility device. XRC will not allow the reserve to be done until the XRC volume establishes a new utility device. If there is only one utility device, XRC will not allow the reserve CCW to be processed.
- 10
- PINNED CACHE MEMORY EXCEEDING MAXIMUM ALLOWED
Pinned data is data that can not be destaged to the real device. IDCAMS LISTDATA PIN can be issued to determine the pinned tracks. Contact your hardware support center.
- 11
- PPRC SIDEFILE SIZE EXCEEDING LIMITS
The control unit is transferring data from cache to the hardware because the storage cache thresholds have been exceeded.
- 12
- PPRC SECONDARY SIGNALED PENDING TO PRIMARY
State change pending has been issued by a PPRC secondary to the PPRC primary.
- 13
- PPRC DEVICE IN PROCESS OF GOING SUSPENDED
An operator has issued a command to suspend a PPRC pair or hardware is suspending the pair because of a hardware problem.
- 14
- PPRC DEVICE IN EXTENDED LONG BUSY STATE
The hardware is currently long-busy and will remain in that state until hardware clears the condition causing the long-busy. This message is issued every 2 minutes or the control unit time interval set by the customer.
- 15
- PPRC DEVICE IN PROCESS OF TERMINATION
- 16
- UNFENCE IN PROGRESS
Hardware is in the process of clearing a fenced condition on the LSS.
- 17
- WAITING FOR CONTROL UNIT RESOURCES
- 18
- DESTAGE OR DISCARD IN PROGRESS FOR FLASHCOPY VOLUME
The control unit is either destaging or discarding data that is downlevel.
- 19
- DEVICE ERROR RECOVERY IN PROGRESS
While the device is recovering, the device is long-busy. Contact your hardware support center to determine device error.
- 1A
- PPRC DEVICE LONG BUSY DUE TO FREEZE
A freeze of the PPRC pairs has been issued by the operator.

- NEW OR INVALID REASON CODE
Either hardware has created a new message code or the message code is invalid. Contact the hardware support center to determine the meaning of this message code.
- sense
- The 32 characters of sense data reported by the device.
xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx
System action
The MIH Exit will periodically retry the queued I/O to the device until the control unit accepts the request. Message IEA482I is displayed for each retry of the I/O request by the MIH Exit while the busy condition exists.
Operator response
Respond according to the reason code provided in the message. Certain conditions have occurred because of XRC, Flash Copy, and Concurrent Copy. If the messages persist contact your hardware support center and follow your installation recovery processes.
