This is where you call the maker of the RAID setup or the person who implemented since the procedure is "not standardized." Only the documentation to your RAID controller or the software that does the RAID can answer this one.
I can't count how many people set up RAID and then lose the documentation.
I have Windows 2003 server..
And have Raid 1 mirror going on...yet one of the drives seems to every now and then stop functioning. I turn it off and unplug and replug its power sata connector and then it resynch's with the other drive and everything is A ok...I'm thinking I may need to send that hard drive in for warranty replacement if it continues to do this.
What I'm wondering is...once I have this HD taken out..and get the replacement completely blank HD...how to i take the broken RAID 1 portion and reestablish RAID 1 with the replacement HD which will be the same size drive as the one that maybe being taken out.
