SQL Services are not coming online

  • Hi All,

    To day we have faced one issue that master database got corrupted. so that we rebuild the database and restore the master database. after that services are not coming up and when i checked sql error log found the below error:

    SQL Server detected a logical consistency-based I/O error: invalid protection option. It occurred during a read of page (1:312) in database ID 2 at offset 0x00000000270000 in file 'H:\SQLTEMP\MSSQL\TEMPDB\tempdb.mdf'. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.

    Please advise

  • stop the sql server service and delete the tempdb files and then restart the instance

  • I tried with all posibilities and unable to bring the services online. Finally i replaced Model Mdf and Ldf files from Template databases and started services now the services are running fine.
