IPLB00A7T POSSIBLE GEN ERROR - NO STORAGE AVAILABLE TO CARVE I/O TABLES

Last updated

Changed in 2021 (information only; no code change).

Explanation

There was insufficient storage available for the input/output (I/O) tables in IB08. IPLB resides in the area reserved for working storage. Working storage may have been generated too small or the processor being IPLed may have too little main storage for the z/TPF system being IPLed.

System action

The IPL ends.

User response

See your system programmer for more information. Verify the size of the processor being IPLed. If this is a High Performance Option (HPO) feature, verify the subsystem configuration. Each additional subsystem adds a large main storage requirement during IPL. This message implies a large mismatch between the available storage and the storage requirements.

If the z/TPF system being IPLed has the minimum main storage, 2 MB, then study the z/TPF system generation reports to determine the size of working storage reserved. Ensure that working storage is at least 521 K + (70 K for each subsystem generated). Verify the action of the memory in the processor being IPLed. A memory failure in the first 2 MB may produce this failure.
