Adding a spare drive to and existing RAID 5 on DL 380 G7

Hi,

We have a DL 380 G7 server with 5 drives configured as RAID 5. It is running VMware hypervisor esxi 6. Is it possible to add a sixth drive to the system to use as a hot spare without affecting the current configuration? If possible without bringing down the server.

Thanks in advance.
