Before you run restart, did you unmount filesystems on the lvm device
and did you have lvm release the iscsi/scsi devices? You have to do this
because the logout causes the existing /dev/sdX devices to get deleted.
If you do not have lvm release the scsi devices when you logout then
that lvm/dm device will be referencing a partially deleted device (it is
not totally destroyed because lvm is still referencing it, but the old
device is not going to do IO).
When you login again below, new devices are created. So you have to run
the lvm commands again.

That should not happen. Are you using the iscsi modules that come with
the distro? Send the /var/log/messages when this happens.
