IEF196I IOS078I 0921,78,XCFAS, I/O TIMEOUT INTERVAL HAS BEEN EXCEEDED

We are getting the above message sporadically on our TEST LPAR. I have searched IBMLINK and had EMC check out the control unit and DASD. Might anyone know why we are getting this error on the master console: IEF196I IOS078I 0921,78,XCFAS, I/O TIMEOUT INTERVAL HAS BEEN EXCEEDED IOS078I 0921,78
