Steps:
=======
1, Take the Basic System information and Reboot the
system to recognize the new LUN

2, After the Rebooting the system check for new LUN or
run qlreconfig command and devfsadm

# /opt/QLogic_Corporation/drvutil/qla2300/qlreconfig
-d qla2300

3, Once the new Disk comes under OS control label the
disk using format menu

4, Check the disk visible in veritas control as invalid

5, Bring the disk into veritas control

# vxdctl enable

6, Verify the new LUN information as Online in veritas
( In this stage it shows online invalid )

# vxdisk -o alldgs list

7, Initialize the new LUNs in Veritas control

# /etc/vx/bin/vxdisksetup -i c2t20d114
format=cdsdisk
8, Again verify the New LUN information in
Veritas ( Now it shows as online status )

# vxdisk -o alldgs list


FOR Example: BDMRP database

9, Create new DG called bdmrpdg using new LUN (206GB)

# vxdg init bdmrpdg bdmrpdg_01=c2t20d114

# vxdg -g bdmrpdg adddisk bdmrpdg_02=c#t#d#

10, Create New Volume for under new DG bdmrpdg

1, # vxassist -g bdmrpdg make vol01 10g

11, Create the File systems on new volumes

# /usr/lib/fs/vxfs/mkfs -F
vxfs /dev/vx/rdsk/bdmrpdg/vol01

12, Check the new volumes status

# vxprint -g bdmrpdg -ht

13, Create new directory for Mount points

# cd /DB04
# mkdir -p BDMRP/ORACLE/admin


14, Check the mount point

# mount -F
vxfs /dev/vx/dsk/bdmrpdg/vol01 /DB04/BDMRP/ORACLE/admin


15, Umount the Mount point

# umount /DB04/BDMRP/ORACLE/admin


16, take the backup and Update the /etc/vfstab file and
mount it again with the mount point

/dev/vx/dsk/bdmrpdg/vol01 /dev/vx/rdsk/bdmrpdg/vol01
/DB04/BDMRP/ORACLE/admin vxfs 3 yes -



# mount /DB04/BDMRP/ORACLE/admin
