Increase the disk first. I using VM Ware. 

Now let's check on server side. Login to the server and execute following commands. 

ls -l /dev/disk/by-path/ 

echo 1 > /sys/class/scsi_device/0\:0\:2\:0/device/rescan <<==  put the correct scsi id

lsblk
growpart -h
fdisk -l /dev/sdc

growpart /dev/sdc 1  <<== you may don't need this line. It depends on the environment.

lsblk
xfs_growfs /data
df -hl

Following steps are for the root Partition. 

echo 1 > /sys/class/scsi_device/0\:0\:0\:0/device/rescan
lsblk
growpart /dev/sda 2
lsblk

xfs_growfs /

Following steps are for extend the Multipath LUN. 

# Current size is 1.5 TB

fdisk -l

Disk /dev/mapper/ORACLE_FASTRECOVERYAREA: 1572.9 GB, 1572864000000 bytes, 3072000000 sectors

# Add another 1.5 TB to the LUN-ID and use the following command to detect the new space

rescan-scsi-bus.sh -a -w -s

service multipathd restart

# Now we can see the another 1.5 TB assign to the LUN-ID

fdisk -l

Disk /dev/mapper/ORACLE_FASTRECOVERYAREA: 3145.7 GB, 3145728000000 bytes, 6144000000 sectors

# Now we need to increase xfs File System. Currently looks like as follow 1.5 TB 

df -hl /fast_recovery_area

Filesystem                           Size  Used  Avail Use% Mounted on

/dev/mapper/ORACLE_FASTRECOVERYAREA  1.5T  981G  484G  67% /fast_recovery_area

# Using following command to increase the Filesystem 

xfs_growfs /fast_recovery_area

# Now we can see the file system is increased

df -hl /fast_recovery_area

Filesystem                           Size  Used  Avail Use% Mounted on

/dev/mapper/ORACLE_FASTRECOVERYAREA  2.9T  981G  2.0T  34% /fast_recovery_area
