IEA317A   SPECIFY UNIT FOR dataset ON volser [OR CANCEL]

Explanation

During system initialization, the system could not find a data set on a mounted volume. In the message text:
dataset
The name of the data set that the nucleus initialization program (NIP) could not find.
volser
The serial number of the volume where the data set should reside.
[OR CANCEL]
The operator may cancel a request to mount the volume.

System action

The system waits for the operator to reply. If the operator replies R 00,xxx, the system may issue messages IEA318I and IEA317A.

Operator response

Do the following:

  1. Enter the command REPLY 00,dev.
  2. Find the channel path identifier (CHPID) defined for the device using the I/O problem determination (IOPD) frame option A5.
  3. Check the CHPID availability for the current physical partition using the channel configuration (CHNCFA) frame.
  4. In logically partitioned (LPAR) mode, use the IOPD frame option A5 and the device number to determine if the device is supported and in which logical partition.
  5. Check if the control unit is powered and enabled to the interface. If the control unit interface path is switched through a 3814, check the switching unit settings.
  6. For 3380 device level selection (DLS) or device level selection extended (DLSE) devices, check if the device enable/disable switch is in the ENABLE position.
  7. If you replied to message IOS120D with the ‘CONT’ command, reIPL the system.
  8. Verify that the devices defined in the IODF are online.
