RAID Migration on HP Smart Array 6402/128 Controllers card

[shermaine_1]

Hi, There,
We are running MS SQL database on HP Proliant G4 380 With RAID 1 Configuration. Currently we have 2 set of RAID 1, One for OS drive and another for Database drive. The 2 HDD for database drive are 15K SCSI UTRA320.
However we are still facing Disk I/O performance issue, so we plan to migrate to RAID 1O configuration which in turn will have 4 HDD to support the database read and Write.
I was told that there is a way of RAID migration from RAID 1 to RAID 10 with my database continue on line and without any harm, but myself do hv any idea on this, and I need carry out this activity on production server directly, I will be very apprecitated if any one can give some information on this.

Best regards
Shermaine
