VG Activation at boot time

Hi Folks!

I've got a k570 Machine with 11.i on it. There are 3 shared VGs configured for this host. I want to supress that 2 of these VGs become active while booting. The other one should be activated.

So I put the following in /etc/lvmrc:
custom_vg_activation()
{
vgchange -a -y -s /dev/vg03
parallel_vg_sync "/dev/vg03"
}

Are these settings right?
Any helpful answers would be appreciated

Regards

I've forgotten...

AUTO_VG_ACTIVATE ist set to Zero.

You'll have to make sure that AUTO_VG_ACTIVATE is set to 0 else the custom_vg_activation function won't get called. Other than that it looks OK to me.

Looks ok to me, although you do not really need the parallel sync line.
What I might suggest is that you also include vg00, just to be SURE it activates properly (if it is mirrored) on boot time.

Re: VG Activation at boot time

AUTO_VG_ACTIVATE=0

which looks into custom_vg_activation

custom_vg_activation()
{
/sbin/vgchange -a y -s /dev/vg03
parallel_vg_sync "/dev/vg03" return 0
}

Hi,

I would suggest you to do the following:

custom_vg_activation()
{

/sbin/vgchange -a y -s
parallel_vg_sync "/dev/vg00 /dev/vg03"

return 0
}

As Melvyn suggested you it is better to have vg00 too.

Good luck!
