-902: I/O error 

Explanation:

During the processing of an SQL statement a read or write operation had to be performed on the data devspace or log devspace. This operation could not be executed successfully. The following reasons are possible:

  1. A SHUTDOWN was performed in the meantime.
  2. A disk is defective.

User Action:

In some cases, the error message contains an additional description of the error which must be interpreted according to the operating system being used.

  1. Use the datatbase administration tool to start the database.
  2. Once the disk error has been corrected, the serverdb must be restored (add backup copies and log information).
