You receive the following errors when an IAM dataset is being extended:
IEC614I extend Failed - RC 216
IEC032I E37-08 from IFG0554P
DFHDS0001 Abend 0B0 / AKEB occurs in DFHDSDS3 at offset x'0B02'.
The IAM dataset was not an DFSMS Extended Format Data set and exceeded 65,535 tracks (4369 cylinders). IAM datasets had been limited to 65,535 tracks per volume unless they were using DFSMS Extended Format.
Resolving the problem
Use IAM V8.1 from Innovation Data Processing, and IBM's support for Large Format Sequential Data sets which was added in z/OS V1.7 and enables you to create a data set beyond the size limit of 65535 tracks. Apply IAM fix P800308 if using an earlier release of IAM to address the abend 0B0.
