/dev/sda1  /dev/sdb   /dev/sdd  /dev/sdf  /dev/sdh

Create partitions on the available hard disks.

# fdisk /dev/sdb

# mkdir /u01
# mkdir /u02
# mkdir /u03

Write information about where to mount partitions when the operating system boots.

# cp /etc/fstab /etc/fstab.bkp.$(date +%Y-%m-%d)
# echo "/dev/sdb1 /u01 ext4 defaults 1 2" >> /etc/fstab
# echo "/dev/sdc1 /u02 ext4 defaults 1 2" >> /etc/fstab
# echo "/dev/sdd1 /u03 ext4 defaults 1 2" >> /etc/fstab

# mount /u01
# mount /u02
# mount /u03
