After scanning the disk in OS,Scan the disks in veritas level by using the below command.
bash-3.00# vxdisk scandisks
Trigger DDL(Device Discovery Layer) to again assign names to
DMP devices
bash-3.00# vxddladm assign names
3.Bringing the disk in to veritas control
vxdisksetup command brings the disks in to veritas volume manager control.By default this will format the disk in CDS(Cross Data platform Sharing ) .
Other formats are sliced and simple. sliced will be used for boot disks.
linux-1uhf:~ # /etc/vx/bin/vxdisksetup -i sdd

If you want to setup the disk in specific format,you can use the below syntax.
#vxdisksetup -i disk_XX format=cds or simple or sliced

VXVM Tutorial 2– Diskgroup Operations
================================================================================
Task:1-Creating the new disk group:
linux-1uhf:~ # vxdg init ORADG Oradisk0=sdd Oradisk=sde
linux-1uhf:~ # vxdisk list

sda auto:none - - online invalid
sdb auto:LVM - - LVM
sdc auto:LVM - - LVM
sdd auto:cdsdisk Oradisk0 ORADG online
sde auto:cdsdisk Oradisk ORADG online
Task:2-Addition of disk:
If you want to add the new disk in to existing diskgroup, bring the disk in to vxvm control using vxdisksetup and add it using below command.
uarena#vxdg -g UXDG adddisk UXDISK3=disk_4
uarena#vxdisk list

disk_6 auto:cdsdisk - - online
Task:3-Removing the disk:
You can remove the disk any time from DG if it’s not used in any volume.

Task:4-Maximum size of volume:
If you want to find out how much size volume we can create from the diskgroup, use the below command.In other word to you can determine the free space of the diskgroup.
linux-1uhf:~ # vxassist -g ORADG maxsize
Maximum volume size: 20822016 (10167Mb)
checking for whilie creating mirrored vol how much size we can create.
linux-1uhf:~ # vxassist -g ORADG maxsize layout=mirror
Maximum volume size: 10409984 (5083Mb)
linux-1uhf:~ #
Task:5-Deporting diskgroup:
After un-mounting the volumes , you can deport the diskgroup.To see the imported diskgroup
linux-1uhf:~ # vxdg list

linux-1uhf:~ # vxdisk -o alldgs list

sdb auto:LVM - - LVM

sde auto:cdsdisk Oradisk1 ORADG online
Note:-Sometimes you may need to use -C flag to import the cluster diskgroup to clear the VCS lock.
# vxdg -C import DG_NAME
Task:7-Re-Naming the Diskgroup:
You can’t the rename the diskgroup while its in imported state.In a order to rename the DG, you need to re-import with new name.
linux-1uhf:~ # vxdg deport ORADG
linux-1uhf:~ # vxdg -n NewDG import ORADG

Method :1 Increasing the volume size-Using vxassist
Step:1
Determining how much space we can increase the volume.
linux-1uhf:~ # vxassist -g NewDG maxsize layout=mirror
Maximum volume size: 6215680 (3035Mb)
Step:2
Re-size the volume using vxassist.
linux-1uhf:~ # vxassist -g NewDG growby ora_vol1 500M
Step:3
Re-szie the vxfs fielsystem using fsadm. (Final size of the filesystem)
