MSIR.0228 Invalid input page sequence number: (expseq), expected: (gotseq)

This message sets the batch and online return codes to a minimum of 20. It indicates that Fast/Backup read an incorrect page from the restore dataset when doing a restore. This can be caused by trying to restore a file from a dump dataset that was not correctly closed, for example the dump program abended. The restore must be re-run from a properly closed dump dataset.
