How do I create a disk group in VxVM?
-
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
