FlashCopy Manager messages
All FlashCopy® Manager messages follow a consistent naming convention whereby each message starts with a five character prefix of IWNAF and IWNRF.
A typical sequence of messages generated by the status job in data set hlq.FCMGR.groupqual.CURRENT.JOBS(Q@STATUS) is as follows.
IWNAF020I 308 DEVICES ARE IN THE 01 STATE - FC ACTIVE
IWNAF021I 308 DEVICES ARE IN THE 01 STATE - NO BCPY P MODE
IWNAF015I COMPLETED PROCESSING FOR 308 DEVICES
A typical sequence of messages generated by the Establish step in the job found in data set hlq.FCMGR.groupqual.CURRENT.JOBS(B$FREEZE) is as follows.
IWNAF010I PROCESSING RECORDS FOR 308 DEVICES
IWNAF600I FRZ DELAY = 1.146 seconds
IWNAF601I I/O DELAY = 1.203 seconds
IWNAF015I COMPLETED PROCESSING FOR 308 DEVICES
Message numbers below 010 identify problems with the input data to the FlashCopy program being run.
The message numbers IWNAF010I and IWNAF015I bracket the FlashCopy operation. IWNAF010I marks the starting point for functions that passed input data validity checking. IWNAF015I marks the ending point of operations against the FlashCopy volumes; the device count in the message will identify the number of devices in the input data set.
- Insufficient region size specified on the job or run statement.
- An internal program logic error.

FLASHCOPY ESTABLISH - FLASHCOPY ALREADY ACTIVE OR NO RESOURCES
Explanation
A FlashCopy Establish request detected that a specified device is in a FlashCopy relationship, or the internal storage subsystem processing detected insufficient resources to complete the Establish of the FlashCopy relationship. This message might be issued if one or both of the specified devices specified in a FlashCopy Version 2 Establish request are in an active FlashCopy Version 1 relationship.
System Action
The program stops.
User Response
The possible causes of this error are as follows: (a) one or both of the devices specified in a FlashCopy Version 2 Establish request is in an active FlashCopy Version 1 relationship, or (b) that another FlashCopy Establish for one or both of the specified devices completed just before this FlashCopy Establish was requested. Use the FCQUERY request to determine the status of the requested devices. If the devices are not in a FlashCopy relationship, this FlashCopy Establish request may be retried later, when storage subsystem resources may be available.

A FlashCopy Establish request failed for a source track because the maximum number of FlashCopy relationships has been reached for one or more tracks contained within the extents that are specified on the request.
System Action
The program stops.
User Response
Use the FlashCopy query request to determine the status of the source device that is specified on the FlashCopy Establish request. Refer to z/OS DFSMS Advanced Copy Services for examples of FlashCopy query output. The FlashCopy query output does not provide information on a track basis, but you might be able to make this determination based on the extents you specified on the Establish request. If the request continues to fail, contact IBM Support.
IWNAF752I
FC TARGET RELATIONSHIP DETECTED ON SOURCE nnnn, SX= ppxxcccc
Explanation
One or more of the tracks on the specified FlashCopy source device is a target track of some other FlashCopy relationship. nnnn is the device number of the source device that contains the unexpected target track. The SX= string provides information on the FlashCopy source device for the relationship that has target tracks on device nnnn. pp is identifies the LSS that contains the source device and xx identifies the device within LSS pp. The cccc data contain the flag bytes that describe the relationship. The flag bytes are provided to assist IBM service and support.
System Action
The program stops.
User Response

User Response
Use the FlashCopy query request to determine the status of the target device specified on the FlashCopy Establish request. Refer to z/OS DFSMS Advanced Copy Services for examples of FlashCopy query output. The FlashCopy query output does not provide information on a track basis, but you may be able to make this determination based on the extents specified upon the Establish request. This message can be also received if an Establish request is completed by the storage subsystem after the missing interrupt handler processing has been initiated. Resubmit the request. If the failure persists, contact IBM Support.
IWNAF766I
FLASHCOPY ESTABLISH TARGET TRACK IS AN ACTIVE SOURCE TRACK
Explanation
A FlashCopy Establish request failed because one or more target tracks contained within the extents specified was found to already be a source track in a FlashCopy relationship.
System Action

User Response
Use the FlashCopy query request to determine the status of the target device that is specified on the FlashCopy Establish request. Refer to z/OS DFSMS Advanced Copy Services for examples of FlashCopy query output. The FlashCopy query output does not provide information on a track basis, but one might be able to make this determination based on the extents you specified on the Establish request. Resubmit the request. If the failure persists, contact IBM Support.

- MSG FRMT = _, MSG NMBR = F, REAS: 60
- The target device for a FlashCopy request is in a path group status. This implies the device is online to a host system (not necessarily to the host issuing this FlashCopy request). Ensure that the target device is offline to all systems, or specify the ONLINTGT(YES) parameter.
- MSG FRMT = _, MSG NMBR = F, REAS: 82
- The subsystem has insufficient resources or too many FlashCopy relationships to complete this FlashCopy request. Resubmit the request when the condition is corrected or the constraint is relieved.
- MSG FRMT = _, MSG NMBR = F, REAS: 84
- The FlashCopy request specified devices that are not in the same logical storage subsystem, or the devices are not the same size and format.
IWNAF799I
AOM DETECTED I/O ERROR, MSG FRMT = f, MSG NMBR= n, REAS: rsn
Explanation
The asynchronous operations manager (AOM) detected an error while handling an I/O request from FlashCopy processing. The message format f, the message number n, and the reason rsn are taken from the sense bytes obtained after the error.
System Action
The program stops.

If the user specifies the device as a 4-digit entity, the (device) subchannel will default to 0.
