| This information was obtained from the H390-MVS files section on Yahoo. Wait State Codes Wait state codes are found in the 12 low-order bits of the PSW when the PSW wait bit (bit 14) is set to one. The PSW format is: yyyy yyyy xxxx xzzz yyyy yyyy This is the left half of the program status word. This half has two forms: 070s0000 If the wait state code (zzz in the right half of the PSW) is 000, no tasks are ready in the system. Otherwise, an error condition, indicated by zzz has occurred. 000s0000 System wait state caused by an error condition. In each of the above forms, s represents bits 12-15 (CMWP bits). xxxx xzzz This is the right half of the program status word. The wait state code, zzz, indicates the error condition. Wait state codes are described briefly in the following table. For complete explanations and problem determination procedures, refer to OS/VS Message Library: VS2 System Codes. Code Explanation ---- ---------------------------------------------------------------------------------- 001 IPL: "Not Operational" is the status of the volume containing the nucleus being loaded. 002 IPL: an I/O operation was not initiated; CSW was stored; channel was not busy. 003 IPL: An I/O operation was not initated because a "not operational" response was received from a SIO instruction; CSW was not stored; channel was not busy. 004 IPL: An I/O operation was not initiated; CSW was not stored; channel was not busy after execution of a Test I/O instruction. 005 IPL: A unit check caused an I/O interruption; the address of the CCW is placed in location x'4C'; the first four unit-check sense bytes are placed in location x'54'. 006 IPL: A interface control check, or channel control check, or channel data check, or program check, or channel chaining check occurred. 007 NIP: A console was not available. 00A NIP: A catalog entry for the SYS1.LINKLIB dataset was not found on or not retrievable from the system catalog. 00B The master scheduler terminated abnormally during initialization; a dump was taken to the SYS1.DUMPxx dataset. 00C IPL: An active nucleus member is not edited in the scatter format; the nucleus cannot be loaded. 00D The master scheduler terminated abnormally during initialization; no dump was taken. 00E IPL: The SYS1.NUCLEUS dataset or active member, IEANUC0x, of SYS1.NUCLEUS is not found on the IPL volume; the system nucleus cannot be located. 00F IPL: An IPLed volume does not contain the IPL text. 013 NIP: An error occurred from which recovery was not possible. 014 Recursive translation exceptions occurred due to incorrect initialization, or overlaying of the master address space segment tables or common page tables occurred. 017 IPL: A unit check occcurred following a sucessfully started I/O operation. 018 IPL: The nucleus is too big for the machine size; the space available for relocation dictionary records was exceeded. 019 IPL: An unexpected program interrupt occurred. 01A An attempt was made to execute multiprocesing modules that were not included in the nucleus when the system was generated. 01B The error condition specified on the SLIP command has been met and the system is placed in a "wait state", as requested. 01C Supervisor control suffered a double recursive abnormal termination in supervisor control super FRR. 021 NIP: An I/O error occurred on the main console following an EXCP operation. 022 A page fault occurred for a duplexed page but primary and secondary devices are either in a quiesced or "not ready" state. 024 The system termination facility failed to receive the expected interruption while attempting to write record to the SYS1.LOGREC dataset. 026 Either a power interruption occurred or the operator replied "REST" to message ICFTIM21. 027 A power interruption occurred, or the operator replied "REST" to the message ICFTIM21, or the operator replied "STOP" to on eof the power warning initialization messages. 029 The time-of-day clock is in error. 02A The hardware could not signal the other processor because the other processor did not appear to exist. 02B The hardware could not signal the other processor, because the other processor has experienced a similar problem and was the first processor to enter the 02A wait state. 02D NIP: An unconditional mount was issued requesting a Mass Storage System device (3850), which is not supported during NIP. 02E ASM can no longer access a required page dataet due to an unusual number of permanent I/O errors. 02F A direct access device containing a page dataset is unavailable for an I/O operation. 030 NIP: An unanticipated request for abnormal task termination (ABEND) has occurred. 031 NIP: The ipl volume resides on a unit for which there is no UCB. 032 NIP: A required module is not found in the SYS1.NUCLEUS dataset by BLDL. 033 NIP: An I/O error occurred during BLDL's processing of a required module. 034 The operating system is incompatible with the procesor.
