Do I need to wipe harddrives in RAID array before combining with new HDs to make new array?
I currently have a RAID-5 array connected externally to a HP Proliant DL380 via built-in SmartArray 5i. I am looking to add a new RAID controller to this machine and want to install a new OS as well. I will take the 4 HDs currently with data, and add them to the internal hard drive space, in addition to adding 2 new HDs.
Do I need to wipe these 4 HDs prior to installing the OS? Or will setting it up with a new arraycard (or of course during the WIndows install) automatically wipe it since it's 6 disks now instead of the 4?
