Penoi's Veritas Volume Manager Notes

This is my personal notes on Veritas Volume Manager. This page is a continuing notes of frequent commands that i use in VxVM

Example:
#/usr/lib/vxvm/vxdisksetup -iv c2t0d0

Creation
Create initial disk group
vxdg init [diskgroup] [disk_name=device_tag]

Example:

Add more disk to the Disk Group
vxdg -g [disk_group] adddisk [disk_name=device_tag]

Example
#vxdg -g newdg adddisk disk2=c2t1d0

Volume Creation

Concatenated Volume

vxassist -g [disk group] make [volume_name] [size]

Concatenated Volume by specifying the disk
