alternate path in PVG

[marc seguin]

I have 2 discs in my VG and 2 paths (primary+ alternate link) for both. And there is a PVG-strict mirroring policy. Two PVG are defined. PVG1 contains the two paths of disc1, and PVG2 the primary path of disc2. (I didn't do the installation !)
Is it necessary to add the alternate link in PVG2 ?
Is it possible with the command 'vgextend -g' ?

Exactly as you say.

you should use
vgextend -g PVG2 /dev/vgXY /dev/dsk/cYtYdZ

you can also manually edit /etc/lvmpvg (in case you do not like the PVG names...)

Hi,

/etc/lvmpvg is a ascii file that can be edited manually.

So you can always edit and insert the alternate path of disc2 .

Thanks,
