mdadm is a popular Linux tool to manage RAID arrays. RHEL provides a usage guide.

After creating a RAID array, or to find an existing array that may or may not be mounted, use commands like:

mdadm --detail /dev/md/Volume0_0

Note the individual RAID disk /dev/sd*, which can be further examined like:

mdadm --examine /dev/sda /dev/sdb

Also examine all available devices with:

fdisk --list

To mount the RAID, use commands like:

mkdir /mnt/raid
# arbitrary location you want to mount RAID device at

mount /dev/md/Volume0_0p1 /mnt/raid

There might be extra devices under /dev/md that can’t be mounted, but one of them should be the desired RAID.
