Hi kumar,

You have to format the lun Please run below command & make partition to new lun.

fdisk /dev/sdb

16) On the server, create the Linux file system on the new partition.
> mkfs -t ext4 /dev/sdb1
mke2fs 1.43-WIP (20-Jun-2013)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
327680 inodes, 1310464 blocks
65523 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=1342177280
40 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736

Allocating group tables: done
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

17) Verify the partition.
> blkid /dev/sdb1
/dev/sdb1: UUID=”1a6e2a56-924f-4e3b-b281-ded3a3141ab4″ TYPE=”ext4″

18) Create the mount point and manually mount the directory.
> mkdir /newiscsilun
> mount /dev/sdb1 /newiscsilun
> df -h | grep newiscsilun
Filesystem Size  Used Avail Use% Mounted on
/dev/sdb1  4.8G  10M  4.6G   1% /newiscsilun

19) Add the new mount point to /etc/fstab.
> vi /etc/fstab
/dev/sdb1 /newiscsilun ext4 _netdev 0 0
> wq!

Note: the _netdev option is important so that it doesn’t try mounting the target before the network is available.
