Dear All,

I have some previously used hard disks containing rootvg and datavg
that is no longer needed. I'd like to use these hard disks on another
machine that requires more disk space. The hard disks are just by
themselves (not attached to any server) and still contain VGDA
information. Can I just put them into the new machine and extendvg -f
VGname PVname and just use them? Is there any steps I need to do
first? Format the disk or clear PVID or anything?

Thank you

You should be able to 'extendvg VGname PVname'.
According to the man page:
If the system detects a description area from a volume group that is not
varied on, it prompts the user for confirmation in continuing with the
command. The previous contents of the physical volume are lost, so the
user must be cautious when using the override function.

Yours,
