DYNAMIC ALLOCATION FAILED FOR device_address CODE = return_code REASON = reason_code

Explanation

VTAM® issues this message in response to a VARY ACT command for a channel-attached major node.

device_address is the hexadecimal address of the link station that failed.

return_code is the return code received from dynamic allocation SVC 99 and indicates the contents of Register 15.

reason_code is the reason code in the parameter list and provides information about the cause of the failure.

System action

VTAM deactivates the link station device_address.

Operator response

  • Verify that device_address is correct. Then, attempt to activate the link station again.
  • If the command continues to fail, save the system log for problem determination.

System programmer response

Use the output provided and the explanation of return_code and reason_code to assist you in correcting the problem.

See the z/OS MVS Programming: Authorized Assembler Services Guide for a description of return_code and reason_code.
  • If REASON = 0214, this indicates that the unit is not available because the device is already allocated.
  • If REASON = 0238, this indicates that space is not available in the task input/output table (TIOT). Increase the size of the TIOT table.

If you cannot determine the reason for the failure, contact the IBM® Software Support Center.
