An I/O error was detected on a read from the TMC.

Verify that the TMC was formatted using TMSFORMT. Verify that the TMC was allocated with DCB=(RECFM=FB,LRECL=340, BLKSIZE=n*340,DSORG=PSU). If the disk on which the TMC is located has been compressed or the data set has been moved, execute TMSINIT and run TMSCOPY to back up the TMC. Specifying DSORG=PSU on the TMC prevents it from being relocated in a DASD defragmentation orion operation.
