Hi,
You can format and mount any disk which is attached a new disk to the server.
You can partition /dev/sdb disk with fdisk tool like below.
[root@deveci ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x786292ec.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

You can format partitioned disk ( ext4 type ) like below
[root@deveci-1 ~]# [root@deveci-1 ~]# mkfs -t ext4 /dev/sdb1 mke2fs 1.41.12 (17-May-2010) /dev/sdc is entire device, not just one partition! Proceed anyway? (y,n) y Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 65536 inodes, 262144 blocks 13107 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=268435456 8 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376 Writing inode tables: done Creating journal (8192 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 29 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. [root@deveci-1 ~]#
You can create related directory and mount this volume group with this directory.
[root@deveci-1 /]# mkdir /oracle
[root@deveci-1 /]# mount -t ext4 /dev/sdb1 /oracle
[root@deveci-1 /]#
[root@deveci-1 /]#
[root@deveci-1 /]# df -h
