You dont need to do any vgexport.Here is the procedure.
-First present the disk to both node
-On the master node just fallow the standart disk addition procedure:
pvcreate/vgextend/lvcreate or extend
-If you create new lv change the permissions and owner to oracle for lv device file.

Re: SLVM Query
Thanks for the response.
Unfortuntely the link is not working and i could not find the Doc on it.
Also i have a quick question, if we do standard procedure as you commented would it update the /etc/lvmtab on the alternate nodes as well? Also how about the PVG file if we use lvm PVG?
Thanks again

Re: SLVM Query
Please find the document from here:
http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?lang=en&cc=us&taskId=101&prodClassId=10008&contentType=SupportManual&docIndexId=64255&prodTypeId=18964&prodSeriesId=4296010
Physical volume groups and the lvmpvg file
The physical volume groups work exactly the same way regardless of the activation mode of the volume group. In particular, you can use physical volume groups for configuration operations (lvextend) on shared volume groups.
The /etc/lvmpvg file is not distributed across nodes automatically. The vgextend command acting on a shared volume group updates only the local /etc/lvmpvg file. This is identical to a standalone activation. The /etc/lvmpvg file is not automatically updated on the client nodes sharing the volume group.
Yes it updates /etc/lvmtab_p on all nodes.

Re: SLVM Query
Thanks for the docs. I got the point. Thanks
But it seems we would need to have the VG deactivated on all the nodes except one. VxVM CVM is more robostic then SLVM it looks as we could make the Changes online without impacthing anything on CVM.
Thanks again.
