[linux-lvm] re-activate lv after reboot ?

[vu pham <vu sivell com>]

My server uses iscsiadm to access a remote iscsi device. VG and LV are 
created on that device and can be accessed just fine.
The problem is after reboot, the LVs are in inactive mode and I have to 
run vgchange -a y to activate the VG on the iscsi device or to put that 
command /etc/rcd./rc.local.

Is there any way to automatically to activate those LVs/VGs when the 
iscsi device starts ?

Thanks,
Vu
