IEA306I dev,chp,I/O ERROR,cm, stat,[sens],[ser]
Explanation
The nucleus initialization program (NIP) issued an I/O request to a device on a channel path. The I/O request included a command that resulted in an unsuccessful I/O completion.
- dev
- The device number
- chp
- The channel path identifier
- cm
- The I/O command that resulted in an unsuccessful I/O completion, if known; otherwise, this field is set to asterisks.
- stat
- The channel status word (CSW) status bytes
- sens
- The first two bytes of sense data
The sense data appears only for errors involving a unit check status.
- ser
- The volume serial number of a direct access storage device (DASD)
involved
The volume serial number appears only for DASD.
System action
If the I/O request is critical to the system initialization process, the system issues message IEA304W and enters a disabled wait state. Otherwise, processing continues.
If the device is a console, the system also issues message IEA193I, which indicates the CONSOLxx member that defines the console where the error occurred.
Operator response
This is probably a hardware error. If the system issues message IEA304W, see the operator response for that message and the associated wait state.
If the system does not issue message IEA304A, restart the system and then contact hardware support. Provide the message text.
