We bought a server about a year ago, it has given nothing but trouble. The raid was configured badly , 4 disk array RAID 10. Now the I/O on the disks is slow and due to a lack or ram , they are constantly paging to the point the server will become not responsive and needs rebooted every 2 to 3 days. So to start with I am looking at putting in new 15,000 RPM disks rather than 7,200. I want to reload the OS on the new disks. Now for my question. I am not experienced with server os's so I want to number the current disks and set them aside. Remove the RAID controller and sit it aside. So if I cannot get the new disks loaded and configured, I can put the old parts back and boot the server for Monday business. Will the LSI raid controller hold the configuration if pulled and replaced as I described?
