I said you also need to have lvm release the devices. What you are doing
is unsupported and the results you are getting are expected.
Before running iscsi stop you need to have lvm stop using the iscsi
devices, because when the stop is done it will remove the iscsi devices
and lvm will be referencing bad devices.
After you run iscsi start you need to run something like lvm vgscan so
the lvm devices are rebuilt using the new scsi devices.
I think you want to email the lvm group to see what commands they
reccommend to run.
For RHEL 5 based systems here is some more info:

I do not think you need to do the lvm commands in there, because I think
those are for permanment removal and your situation has the iscsi
devices coming back right away. Maybe you just need to run a vgremove (I
am not sure, so like I said before it is best to ask the lvm people).
Also why are you even running iscsi stop?
