The Perc6/i controller can support you doing that all without having to power down the server, as long as the drives are hot swap. You can pull a drive and see the array go degraded, and then reboot under the single drive and then after reboot insert the pulled drive and watch it rebuild to optimal.
Hi, I have 2 Dell Poweredge R610 servers and I'd like to do some testing.Both servers have 2 x 150GB  Dell Perc 6i SCSI disks configured in RAID 1. As part of my test plan, I want to: 1. power down server and pull out a single disk2. power server back on and  see if it boots OK with a single disk3. after 10 minutes power server off and put the disk back in4. power server back on and allow RAID 1 to rebuild mirror Would this work? Bearing in mind both servers are to be production servers, The only thing I'm a littke worried about is that disk failures are most likely to occur during a RAID re-build. I'd hate to be in a situation where the servers are killed all together. Please advise if this is a fairly safe approach to take. Thanks
