Error description

• An I/O operation may report the following error into the server
  activity log (note the "CC=204" completion code):
  
  
  ANR8300E I/O error on library LIBRARY (OP=00006C02, CC=204,
  KEY=06, ASC=28, ASCQ=00, SENSE=
  70.00.06.00.00.00.00.0A.00.00.00.00.28.00.00.00.00.00.00-
  .00.00., Description=Recovered from an I/O error; for
  your information only). Refer to the
  IBM Spectrum Protect documentation on I/O error
  code descriptions.
  
  
  Despite the above, the operation will end successfully.
  
  
  
  
  Customer/L2 Diagnostics:
  When the failed I/O operation is fully recovered, the driver
  sets the compCode code as value as
  204. This compCode tells the server that the device driver
  recovered I/O error. Therefore the I/O
  is successful. However, the driver sets this compCode as 204,
  but sets a non-zero value to rc. It
  means the device operation had errors. This rc value causes the
  server fails the I/O operation. The
  correct rc value should be set 0 in this case.
  
  The DD trace will look like as follow:
