How do I create a disk group in VxVM?

[petulia3478]

If your disk in a completely new to VxVM, then you need to run vxdisksetup on your disks, to allow VM to use them, then do the following:

# vxdiskadd c2t2d0

# vxdg init engdg engdg01=c2t2d0s2 

Note here is newly create disk groups in 4.0+ are CDS, cross-platform data sharing compatible. This default is set in the /etc/default/vxdg

You can use the following to turn off CDS

# vxdg -g diskgroup set cds=on|off

Where diskgroup is your disk group name
