I am getting these errors on my dedicated server because of which database goes into recovery mode.
I have seen the following error in SQL server error log file:
2018-01-20 05:32:19.83 spid7s LogWriter: Operating system error 1117(The request could not be performed because of an I/O device error.) encountered. 2018-01-20 05:32:19.83 spid7s Write error during log flush. 2018-01-20 05:32:19.84 spid284 The client was unable to reuse a session with SPID 284, which had been reset for connection pooling. The failure ID is 46. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message. 2018-01-20 05:32:19.84 spid335 Database newtrack was shutdown due to error 9001 in routine 'XdesRMFull::Commit'. Restart for non-snapshot databases will be attempted after all connections to the database are aborted. 2018-01-20 05:35:03.35 spid22s Recovery completed for database aa(database ID 7) in 151 second(s) (analysis 18856 ms, redo 115386 ms, undo 2023 ms.) This is an informational message only. No user action is required.
At the same time following errors are generated in event viewer:
