05E

Explanation

An I/O error occurred while the system attempted to read the master catalog self-describing records.

The wait state can be caused by one of the following:
  • The VVDS entry for the master catalog is damaged.
  • The master catalog name, volume serial or both in the SYSCATxx member of SYS1.NUCLEUS is incorrect.
  • A hardware error was detected.
  • A catalog was moved to a different volume serial and the SYSCATxx member was not updated.
  • The SYSCAT entry of LOADxx produced an incorrect master catalog name.
The first ten records in the master catalog data set describe the master catalog itself. They are the catalog entry for the master catalog.

System action

The system enters a non-restartable wait state.

Operator response

ReIPL the system and report this wait state code to the system programmer.

System programmer response

Do the following:
  • Check the the master catalog name and volume serial in the SYSCATxx member of the SYS1.NUCLEUS. If the name or volume serial is incorrect, correct it and have the operator reIPL the system.
  • If the master catalog name is correct, look for a problem with the VVDS entry for the master catalog.
  • If neither the master catalog name nor the VVDS entry for the master catalog are in error, this is probably a hardware error. Contact hardware support, providing one of the following:
    • Run the IEBPTCH utility to print the cataloged procedure.
    • Issue the access method services LISTCAT command to list catalog entries and information about objects defined in the catalog.

The master catalog must either be recreated or restored to the proper volume after the damage to that volume is corrected.
