Check the docs above...

Adding disks to MC/SG - are you creating a new vg or adding to an existing?

Adding to existing is pretty straight forward.

Just vgextend the vg with the new devices, extend (or lvcreate new lvols) existing lvols. Make a new map file:

vgexport -p -s -v -m /tmp/vgXX.map /dev/vgXX

Copy that to second node. On the 2nd node, vgexport /dev/vgXX ; mkdir /dev/vgXX ; mknod /dev/vgXX/group c 64 0xHH0000 ; vgimport -s -v -m /tmp/vgXX.map /dev/vgXX

XX is decimal value of your vg and HH is Hex minor number.

If you created new - then you also have to update the package cntl scripts on both nodes...

Rgds...Geoff
