039

Explanation

The system could not mount a direct access volume because the mount request conflicted with another volume. One of the following occurred:
  • Both volumes were required by the system.
  • Both volumes had the same volume serial.
  • The volume to be mounted required a different device type than that containing the online volume.
  • The system could not find a proper device on which to mount the volume.

System action

The system enters wait state X'039'.

System programmer response

If any IGGNxxx messages are issued with this wait state code, perform the system programmer response for these messages. Otherwise, change the volume where one of the two data sets resides. Update the catalogue to contain the volume of the moved data set.
