Reason:
When the CA 1 system option LCHG is set to NO, CA 1 rejects a scratch tape that is mounted for output if its label type differs from the requested label type. For example, if a scratch tape previously created with standard labels is mounted to satisfy a request for an ANSI label tape, CA 1 does not allow the system to relabel the tape from SL to AL format. The volume is rejected with message IECTMS3O or IECTMS3E "dddd,vvvvv IS NOT SCRTCH (88)".
Action:
The CA 1 Health Check component issues this message. The component provides extensive detail on the problem and the suggested response. The following actions and responses are documented for this check:
System Action: Any scratch tape that requires dynamic label change is rejected for output and dismounted. Other mount requests are issued until a tape with matching label type is found. Unnecessary mounts and dismounts may delay tape jobs. If the request cannot be satisfied, tape jobs may fail. Rejected volumes in an Automated Tape Library may be put in error status and may require manual intervention.
Operator Response: Notify the systems programmer of this potential problem.
System Programmer Response: The system option LCHG is set to NO. To allow dynamic label editing, change this option to YES. To authorize specific users for specific label change actions, set the option to EXT. If you set this option to EXT, CA 1 calls the external security system with more information including from/to label type, tape volume serial number, and unit. Certain security resources must be defined to your security system and certain access rules must be created to control dynamic label change.
Problem Determination: To display the current values of all your options and other information about the CA 1 Tape Management system, use ISPF panels.
