Explanation
An error was detected while attempting to open
the input data set or while processing continuation diskettes of the
multivolume input data set on the device. A continuation diskette
is any diskette in a multivolume file except the first one. The sequence
error is a result of one of the following conditions:
- The continuation volume in the drive unit does not contain a HDR1
label describing the data set being processed. This condition may
arise because diskettes with incorrect VOL1 or HDR1 labels have been
flushed.
- The volume sequence number in the HDR1 label describing the first
extent of the data set was one. The volume sequence number in the
HDR1 label describing the extent now in the drive unit is a value
other than one greater than the previous volume sequence number.
- The volume sequence number in the HDR1 label describing the first
extent of the data set was non-blank and was not 1.
- While opening a data set, a volume sequence number of other than
blank or one was found in the HDR1 label.
- While opening a data set, a multivolume indicator of L was found
in a HDR1 label with a blank volume sequence number.
In the message text:
- ddd
- The device indicated.
- dsid
- The multivolume input data set.
System action
Wait for operator response and continue processing.
Operator response
Provide the correct diskettes in the correct
order, without any intervening diskettes, and enter REPLY xx, ‘R’
to retry and continue reading the multivolume file. If unable to provide
the correct diskettes in the correct order, enter REPLY xx, ‘C’ to
cancel processing of the data set.
Programmer response
Ensure that the diskettes for the multivolume
file are contiguous and in the correct order before submitting the
job.
