Hi,

I needed to add a new volume group to my cluster.

Rgds.,

No, downtime isn't necessary.
Shortly:

# ioscan -fnC disk; insf -C disk
# pvcreate /dev/rdsk/cXtYdZ
# mkdir /dev/newvg
# mknod /dev/newvg/group c 64 0xNEWMINOR

--> where NEWMINOR is a free minor number, look at the output of the following command and select the next free minor number

# ll /dev/*/group | sort -k 6

# vgcreate /dev/newvg /dev/dsk/cXtYdZ
