M204.2149  I​/​O error on TAPE5 dataset​,​ application of index updates aborted

An unrecoverable I/O error has occurred reading the TAPE5 data set during Z command processing. No further application of index updates is possible, and the file will be marked physically inconsistent.

File manager response: Refer to CCAAUDIT or the console log for more specific messages related to the error. Before the Z command can be rerun, the file must be returned to the state it was in prior to execution of the failed Z command, and the I/O error must be corrected or circumvented.

A RESTORE or a ROLL BACK can be used to return the file to its state prior to the Z command. The I/O error might be corrected by copying the TAPE5 data set to another device, but a safer course of action will usually be to recreate the data set by rerunning the sort which produced it.
