AVZ0500E IBM-assigned CSR table entry setup error, contains val, not product OPVN pointer
Explanation
During initialization, the product Vendor Vector Table entry contained an invalid value (val). The assigned fullword contains a value which does not address the product OPVN control block. The IBM-assigned, entry in the table is located at decimal offset 184, hexadecimal offset B8 of the vector table addressed by ECVTCTBL. The fullword value at that location contained a non-zero value that did NOT point to an already established product OPVN control block. The product cannot initialize without establishing the OPVN block pointer. The existing value in the vector table fullword is saved and overlaid with the product OPVN block address.
User response
Determine who/what is responsible for creating the invalid entry in the table, clear the word to x'00's, and restart the product. Caution should be used when deciding to clear the entry. Most likely, another ISV has inadvertently used this entry; clearing it to 0's could cause problems for some other product.
