Как запустить MSSQL Server с поврежденной моделью db

Фактически это было исправлено некоторое время назад (еще в июле 2012 года) с помощью платного звонка в службу поддержки Microsoft.

Поскольку это получило так много просмотров, я решил добавить отредактированную версию нашего «электронного сообщения» о звонке в Microsoft.

===========================

From ERRORLOG we can see that SQL SERVER trying to bring model database online but since model database in recovery state hence we were unable to run database recovery.

We also know that whenever SQL SERVER start we recreate TEMPDB database by coping the content from model database.

Now since model database didn’t started hence TEMPDB startup also failed which is one of critical system database and this caused SQL SERVER service to failed


Solution:
=====================================
·         To fix this issue we started SQL SERVER EXE with following parameter from command prompt


SQLSERVR.EXE -c -T3608

·         Then after we detached model database using following T-SQL


sp_detach_db model

·         Then after we attach the model database using following T-SQL


================================
USE MASTER
GO
CREATE DATABASE MODEL
      ON (FILENAME = 'C:\PROGRAM FILES\MICROSOFT SQL SERVER\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\MODEL.MDF')
      FOR ATTACH ;
================================

·         After that SQL SERVER service came online successfully

Можете ли вы запустить службу sql, минуя автовосстановление?

net start mssqlserver /f /m /t3608

потом попробовать восстановить модель?

sqlcmd -e 
restore database 
model go
