Veritas Volume Manager - VxVM 7 - Linux - Create DiskGroup, Volumes and Filesystems

Create Disk Group, Volumes and File systems:

- Initialize the disk
vxdisksetup -i sdb

- Uninitialize the disk    
vxdiskunsetup -C sdb

- Initiate or Create a disk group  
vxdg init datadg datadg01=sdb

- Add disk to disk group  
vxdg -g datadg adddisk datadg02=sdc

- Remove disk from disk group
vxdg -g datadg rmdisk datadg03

- Rename device name in Volume Manager  
vxedit -g datadg rename sdc datadg02

- Destroy disk group
vxdg destroy datadg    


/dev/vx/dsk/diskgroup/volume_name - When data is written to files, it is actually written to the block device file
/dev/vx/rdsk/diskgroup/volume_name - When fsck is run on the file system, the raw device file is checked

- Check for maximum available size
vxassist -g datadg maxsize  
vxassist -g datadg maxsize layout=mirror

- Create a volume
vxassist -g datadg make datavol01 100m

- Create a volume with mirror copy  
vxassist -g datadg make datavol02 100m layout=mirror

- Add mirror copy for a volume
vxassist -g datadg mirror datavol01 datadg03

- Remove volume from disk group
vxassist -g datadg remove mirror datavol01  

- Create a file system
mkfs -t vxfs /dev/vx/dsk/datadg/datavol01
mkfs -t vxfs /dev/vx/dsk/datadg/datavol02

- Create mount point
mkdir /data01
mkdir /data02

- Mount a file system
mount -t vxfs /dev/vx/dsk/datadg/datavol01 /data01
mount -t vxfs /dev/vx/dsk/datadg/datavol02 /data02

Add entry in /etc/fstab to make it persistent after reboot
