Explanation
A program issued a request to read a volume label
on a device. The I/O request included a command that caused an unsuccessful
I/O completion.
In the message text:
- dev
- The device number.
- chp
- The channel path identifier (CHPID)
- cmd
- The I/O command that caused the error.
- stat
- The subchannel status word (SCSW) status bytes.
- text
- A variable length text string that is one of the following:
- SENSE FOLLOWS
- This text appears for unit check errors in which the resulting
sense data could be successfully read. If this text is displayed,
the sense data is also displayed.
- sense-data
- Shows up to 32 bytes of the resulting sense data in the second
line.
- INVALID SENSE DATA
- This text appears for unit check errors in which an I/O error
also occurred while trying to read the resulting sense data.
Note: If
this situation occurs, no second line of message IEA307I is displayed.
- NO SENSE DATA
- This text appears for non-unit check errors. Since the error
was not a unit check, then no sense data exists.
Note: If this situation
occurs, no second line of message IEA307I is displayed.
