Re: MC/SG Add additional PV

A few other general things to consider before any of the above, so life would be easy:
1- Make sure your VG can accept extra disks for expansion (meaning MAX PV)
2- Make sure you can do "pvcreate -f /dev/rdsk/c..t..d.." on both nodes and all the paths.(This checks that all nodes can see the shared disks before you go any where!) and no harm is done by doing it again from the mother node.
3- Make sure all nodes can handle vgcreate and are not limited by "MAX VG"
4- Make sure your add on disks are the same size (do not buy the story that yes it is ok) it will come back to hunt you.
5- If any of the LVs were stripped, you need to do vgextend with multiples of disks previously involved in stripping.
6- Always do make an ignite boot recovery before messing with VGs or Kernel changes.
