Hi

We have Dell  Power Edge R420 where it’s configured with RAID 10,So we would like to RAID10,but seems we can’t expand the RAID10 with current controller PERC H710 Mini

Since we have installed 4 new disks ,So we plan to create new RAID ,But we seen 3 disks showing as Foreign  disk and one disk shows as Online

So just wanted to check that if I clear Operation Manager, will it cause any data loose with existing disk in RAID10.

Please find the attached document where I m trying to clear Foreign configuration, it’s giving some warning information, so just wanted to check with you correct method to clear Foreign configuration .
