Adding SATA hard disk to T440
Greetings!
I am adding 16TB x 1 SATA HDD hot-plug hard disk to add more storage in our Dell PowerEdge T440 Server, that currently has RAID-1 (446GB x 2 SATA SSD) and RAID-5 (3725GB x 4 SATA HDD). The added new HDD is in the current state Ready (not Online).
Question: What is the best way to add this additional hard disk? Can I add this to the existing RAID-5? Or, will it be better to create a new Virtual Disk? I am okay either way and I really appreciated any guidance.
Thanks a lot for your help!

Hello ebk528,
It is always recommended you verify the status of your backup before doing any changes on the array(s).
You could create a single drive RAID 0 to get the full capacity.
You could also do Online Capacity Expansion (OCE) to add it to the RAID5. It will not use the entire 16TB. It will only use up to the smallest drive capacity in the RAID5. So that would mean it would use up to 3725GB of the 16TB drive. The rest is unusable.
If you do the OCE, make sure you beginning and ending RAID level is RAID 5.

Thank you very much Charles R. I really appreciated your help.
If you don't mind, can you please send me link or guidelines how to create virtual disk from single drive with RAID-0?
Thank you!

Thank you very much Charles-R and Young-E. I successfully add the new 16TB hot-plug hard disk using RAID-0.
Cheers!
