When we are running a job which writes to a tape abended with below system and return code:
CEE3195W The SNAP dump file could not be opened.
CEE3250C The system or user abend S637 R=0000002C was issued.
From entry point READ_CHIS_CON1 at statement 1752 at compile unit offset at address 0EC53F82.
Abend code explaination: S637 : The error occurred at an end-of-volume for a data set on magnetic tape or an end-of-volume during concatenation. This system completion code is accompanied by message IEC026I. Refer to the explanation of message IEC026I for complete information about the task that was ended and for an explanation of the return code (rc in the message text) in register 15.
Explanation: The error occurred during end-of-volume for a data set on magnetic tape or an end-of-volume during concatenation.
In the message text:
rc - Associates this message with system completion code 637 and with the return code.
jjj - The job name.
sss - The step name.
ddname[-#] - DDname (followed by a concatenation number if it is part of a concatenation and not the first DD statement in the concatenation).
dev - The device number.
ser - The volume serial number.
mod - The name of the module in which the error occurred.
dsname - The data set name.
Return Code Explaination: 2C - An I/O error occurred while rewinding a magnetic tape volume prior to verifying the volume label.
The operations who are responsible for this told us that tape was expired and they got SMS to extend the tape expiration. I did not undertsand what that meant. But when the jobs ran again, they abended with the same error. This job processes huge volume of records and put them on tape. Also, its not that this job is abending as soon as we are running it...it processed some 47 lakh records beofre it abended with above system and return code. Can oneone explain what needs to be done to resolve this. Maybe someone with storage group can help me out with this.
