Smart Array P440ar add a second raid

[alexkg2]

hi everyone,
installed:
server: ProLiant DL360 Gen9
controller: Smart Array P440ar
Firmware Version 3.56

4 HDD raid 10
Model EG0600JETKA
Media Type HDD
Capacity 558 GB

The server has esxi 6 installed
I need to expand the space on the esxi storage

our store sells disks
HDD HPE/1.2TB SAS 12G Mission Critical 10K SFF BC 3-year Warranty Multi Vendor HDD

P28586-B21  part number

I plan to buy two disks

question:
1) can we install them in our server, make another raid 1 from 1.2 TB HDD?
2) will the esxi storage see this new raid 1
