At my client site:
One of his disk went down on a raid 4, the raid reconstruct the disk or what ever its supose to do when a disk goes down.(i dont know that much hardware)

Now when i start the database, i have :
ORA-01122: database file 1 failed verification check
ORA-01110: data file 1: 'C:\ORACLE\ORADATA\ORCL\SYSTEM01.DBF'
ORA-01207: file is more recent than controlfile - old controlfile

If i check the dates of my 2 control files, they seem fine, but oracle dont see it that way, anyways, now i have to recover from backup. Il be ok in 1 hour. But the real problem is the following.

One of the major reason to have a raid configuration, is that if a disk goes down, the raid reconstruct the failed disk and life goes on right?
But then its does something to my oracle files and when i try to startup the database, its says my files are srewed.

If someone has links or info on how to configure raid so it wont mess my oracle files, please dont hesitate.
