The data will be lost if you configure the SATA disks. I'm assuming (RAID 0/1/10, non-RAID capable) that you have a PERC H200 controller ... RAID 5 is NOT supported on the H200.
Hi, I have a problem which I have not idea how to deal with. We have Poweredge r610 that was bought with one SATA hard drive. This hard drive wasn't configured as virtual disk.  Later, an additional SATA disk was added, and not configured as virtual disk as well.I bought 4 SAS disks in order to configure them into RAID 5 and move the whole data from the SATA disks. I have connected to the OpenManage in order to configure the RAID5, and I can't do it , because it force me to configure only RAID 0\RAID1\RAID 10. I guess it's because of the 2 SATA drives. By the way, all the disks are in state "Ready". Is there anyway I can configure the SAS disks to RAID 5 without configuring the SATA drives? I am really afraid the data will be lost. Thanks!
