linux - How can I add a single SAS drive to a Perc H700 on Dell R310 server WITHOUT loosing the data on it?

On a Dell R310 server with Perc H700 RAID controller.

I have 1 virtual disk configured as Raid 1 but with only 1 physical SAS disk attached and the other missing. This virtual disk has been configured with fresh CentOS 6.9 and boots normally.

I now have another physical SAS disk containing some recovered data. Can I create a second virtual disk again containing only 1 disk WITHOUT loosing the data on it and then simply mount it in the OS? I am afraid it will initalize and erase the disk if I do that. How can this be accomplished? We don't have other options for reading the SAS drive. I am not able to find any guides relating to this scenario.

Reading the manual it seems I should be able to create a VD and then NOT initialize it. Would this make it accessible to the OS (f.ex. like would it allow linux to create a /dev/sdX device)?
