Hi Experts,
I tried moving one of our user DB using 1.mode database offline..moved files run alter database modify files and made database online..it didnt took old .ldf file instead created a new file in old path. 2.detach\attach method. It threw error and failed to attach. then successfully added the file using sp_attach_single_file_db but the problem is my old 21gb ldf file is not using now.
How can i move the ldf file successfully attach the old ldf file

If you attached just the data file and had SQL rebuild the log, that old log file is now useless.

Oh dear, you too have fallen fowl of moving database files under SQL Server. Keep an eye out for my SSC article coming soon on how to carry out this process successfully

If the DB was brought online and a new log file created, the old one is completely useless and cannot be used.
Correct your alter database statements (I guess you didn't specify move for the log file), take the DB offline, move the new log file there (the old one will be useless) and bring the DB online.

Well, if you really can't wait for my guide to be published perform the following;
- get details of the current paths\filenames using this query
select name, physical_name from sys.master_files where database_id = DB_ID('yourDB')
- For each file you wish to move build a MODIFY FILE command. For the log file for instance use
ALTER DATABASE [yourDB] MODIFY FILE(name=yourDB_Log, physical_name = 'new drive:\ new path\ new path\yourdb_data.ldf')
- issue the ALTER DATABASE statement
- take the database offline
- copy the file to the new location
- bring the database online
- delete the original file from the original location

Thanks Perry,
So first we have to run the ALTER database MODIFY FILE and then only we have to take database offline right?

That's the order i prefer to do it in. Set the paths and confirm that sql server has updated the system catalogs, you will receive a meesage indicating that the new paths have been accepted and will be used next time the database restarts

Did everything on that order by failed.
SQL error log is showing this. FileMgr::StartLogFiles: Operating system error 2(The system cannot find the file specified.)
