Message
Our SQL server is logging following message. Most of these message are
logged by spid 2: (lazyWriter)
SQL Server has encountered 1 occurrence(s) of IO requests taking longer than
15 seconds to complete on file [I:\XXX_Data.MDF] in database [XXX] (17).
The OS file handle is 0x00000554. The offset of the latest long IO is:
0x000000175b8000
Any idea how can i get to the bottom of it.
Thanks

run DBCC CHECKDB command to see what is going on.

This message was introduced from SQL 2000 SP4. This denotes that I/O
processing of SQL Sever is slowed down. This normally comes if the disk
write speed is slow down.

I know that its a disk performance problem.. Ours is a RAID5 setup.
We have done the disk diagnostic, but it came up with no errors...
Another question is why LazyWriter process is logging it..

This is a diagnostic message, that indeed may indicate that things are
not really up to shape. But if it occurs only occasionally, I would not
take any action now more than to continue to monitori the situation.
