Error description

• OEM code overlays UCB volser (UCBVOLI) with Zeros (zero).
  See Z-page for OEM vendor and fix.  Resulting messages are:

  .
  The overlay is a four byte overlay of binary zeroes (the last
  two bytes of UCBVOLI plus UCBSTAB and UCBDMCT).  The original
  cause of the overlay is that someone wasn't using the proper
  initialization values when accessing the storage pointed to by
  TCTIOTBL.  Normally SMS will allow extra space for multi-volume
  requests by using DUMMYs, but in this case there wasn't enough
  space in the table to hold all the entries for each required
  device (because the OEM had invalidly added devices), and the
  table is spilled over into other storage -- an allocation
  control block called the GQUE.  Allocation picked up a bogus
  address from this control block and updated a UCB, which was
  not its intent.
  Additional Symptoms:  See also the NOTE in OW19266.
       MsgIEF457I display shows truncated VOLSER and VOLSTATE.
  E.g.:
          IEE457I 06.55.09 UNIT STATUS 502
          UNIT TYPE STATUS        VOLSER     VOLSTATE
          0D38 3390 O             HMW2           /RSDNT
  instead of:
          IEE457I 09.36.35 UNIT STATUS 735
          UNIT TYPE STATUS        VOLSER     VOLSTATE
          0D38 3390 O             HMW223     PRIV/RSDNT
  

Local fix

• See Scratch Pad for OEM name and fix information.
  Also, a Vary ONLINE of the drive with the incorrect volser
  should correct the situation.
