Windows 10 Pro not showing my other HDDs.

Hi,

After a fresh Windows 10 Pro installation my other HDDs are not showing.

231GB LSI Logical Volume SCSI Disk Device (SAS(Serial Attached SCSI) ) (Windows 10) Raid 1
1863GB Western Digital WDC WD20EFRX-68EUZN0 ATA Device (SATA ) (only this drive showing)

In BIOS(latest updated few months back) all the drive showing accordingly.

I have installed all the drivers from hp for HP z820 workstation.

Any help would be appreciated.

Thanks.
