Attach db failure cause log not primary

Hi Everybody,

I need URGENT help with this. Because of space problem my collegue create a second log file on another drive. I wanted to clean the thing, made a detach, renamed the ldf into old, but now it won't attach anymore, I get the following messages:

EXEC sp_attach_db @.dbname='TARIFINFO_GEN',
@.filename1 = 'F:\Data\TARIFINFO_GEN_Data.mdf'

Server: Msg 5171 F:\Data\TARIFINFO_GEN_log.ldf is not a primary database file
Server: Msg 1813 Device activation error the physical file name 'F:\Data\TARIFINFO_GEN_log.ldf' may be incorrect

Do someone know what to do or where to look for a solution. Many thanks in advance, Isabelle.Try sp_attach_single_file_db 'TARIFINFO_GEN',
'F:\Data\TARIFINFO_GEN_Data.mdf'

Also, in many instances to clean logs you should be able to run something like:

backup log TARIFINFO_GEN with truncate_only

and then a dbcc shrinkfile.

Instead of detaching and re-attaching.
