Hi Hari,

Ok, basically the same applies here as to your other post: if this is a production system then please open a Prio Very High Support message.

Although this forum is frequented by many experienced users and even MaxDB Developers it's not as tightly monitored as the Support messages are.

Concerning the problem: is the LOG Volume really available at that path (/sapdb/BW7/saplog/DISKL001) ? Is it perhabs locked by a different process (fuser ... ).

Have you tried to restart the server and then the db? Does the error still occur after that?

Best regards,

Lars

Hi Lars,

Thanks for the answer. My error occured because when restoring db i failed to restore the LOGvolume back up. I did this and restarted. Now my db is working fine..

Thanks again..

regards,

Hari
