RAID expansion on Smart-1 5150

Hello,

We have several Smart-1 5150 appliances (in fact just DELL servers) that are already in production. I see that 3 disks for some reason are not recognized by RAID. 6 disks is a default configuration and we bought 3 more. I believe, that they were not added to RAID initially and now we decided to add 3 more disks to have 12x4TB setup.

Question: during RAID expansion will the data be retained or we have to consider backing it up? These devices are  log servers and it is crucial to keep all the logs.
