Sounds like your VG has not been activated by your distribution's init

symlinks are guaranteed to be persistent.
What distro are you using here? Some perform a vgchange -ay from the
iscsi initialisation script (Fedora and RHEL both do this). If that's
Actually, I'm wrong - for Fedora/RHEL/CentOS the vgchange is done from
the netfs script rather than directly from the iscsi script, but only in
the case that at least one entry in /etc/fstab or /etc/mtab has the
"_netdev" option present.
RHEL/CentOS up to 5.2 have a bug in this script that may cause devices
to be misssed due to not syncing up with udev - see:

Looking on my f9 boxes, this bug still appears to be present in Fedora,
will clone the BZ for rawhide if it's still there too.
