In performing a swap, the volume that had been on the "FROM" device was not put on dev. This message appears only for tape swaps.
The system continues operation.
Remove the volume on the device with device number dev and replace it with the correct volume serial, label type (AL, NL, NSL, or SL), and sequence number (nnn). This message can be repeated as many as five times if a wrong volume is consistently mounted, then IGF509D is issued allowing you to reply ‘NO’ to the swap request or select another device.
