Dear Members, Good Morning. We are having an issue in recent days in SQL Server 2005 while fetching data from drive. We are encountering the following Issue from Database Servers and the Error is logged like : Message SQL Server has encountered 7 occurrence(s) of I/O requests taking longer than 15 seconds to complete on file [XXXX.mdf] in database [YY] (6). The OS file handle is 0x000007CC. The offset of the latest long I/O is: 0x000006c6648000 . To resolve the issue we are moving the Data files from one drive to another drive and after that we are formatting the SAN Drive. Can someone help me how to resolve this issue. Regards,Thulasi.
