IEA000I   dev,err,cm,stat,sens, {dcbctfd|opxxterm|cylntrck} [ser],jjj[,hh.mm.ss] --or-- dev,err,cm,stat - MESSAGE EXIT UNAVAILABLE - [exitname]

Two consecutive commas or a field containing blanks or asterisks in the message text indicates that a field could not be determined or is contained on the next or previous line of the message. If the sense data to be inserted in the sens field of the message text exceeds 6 bytes, the sens field and the optional field that follows (dcbctfd or opxxterm or cylntrck) do not appear on the first line. Consecutive commas appear instead. The system then issues a second line that includes the device number of the device, the sense data, and, optionally, dcbctfd, opxxterm, or cylntrck. In other words, if the sense data exceeds six bytes, the message has this format:

IEA000I  dev,err,cm,stat,,,[ser],jjj
         [,hh.mm.ss]
IEA000I  dev,,,sens {,dcbctfd|,opxxterm|
         ,cylntrck}

In the message text:

dev

Device number of the device or line address of the telecommunication device, in hexadecimal. If the error is a channel program check (CPC) or channel protection check (PRC), this field is zeros; the error was not caused by a hardware error on the device, but was caused by the program issuing the I/O.

err

Description of the error based on status and sense information:

• DSN - data streaming is not operational.
• RST - the I/O Restart routine was entered by Alternate CPU Recovery, the Channel Check Handler, or the Missing Interrupt Handler.
• UEX - unit exception.

cm

Command code, in hexadecimal, of the channel command word (CCW) being executed when the error occurred. If the channel command word cannot be found, this field appears as **.

stat

Status portion, in hexadecimal, of the channel status word (CSW).

sens

These bytes, in hexadecimal, describe a unit check type error condition. These two bytes appear if a unit check condition is indicated in the stat field. The number of sense bytes depends on the device type. For devices which give more than six sense bytes, this field continues on the second line of the message. For DASD devices, this field contains the 8 sense bytes for program errors or 24 sense bytes for equipment and data checks.

The message on the system console reflects the sense-byte information from the last entry for direct access devices; the sense-byte information located in the logrec data set data reflects the data from the initial error condition.

debctfd

Record count, in hexadecimal, not including label records. This field appears only for magnetic tape and indicates the count of the record preceding the error record.

cylntrck

Address, in hexadecimal, of the cylinder (cyln), and the track (trck) where the error occurred. When an error occurs while trying to obtain this data, the last seek address is substituted. This field appears only for certain disk and drum direct access device errors.

ser

Serial number of the volume on which the error occurred. This field appears only for magnetic tapes or direct access devices.

jjj

Job name. If the error is a channel program check (CPC) or channel protection check (PRC), this field indicates the program in error.

hh.mm.ss

Time that the message was received in hours, minutes, and seconds.
