the current version of targetcli does not run on Debian 9. The fastest
way to obtain the same is to install fedora server. There is a pretty
recent version of targetcli which supports alua. In order to do the
setup the following commands need to be executed:
# create a standby alua group
cd /backstores/fileio/shared-01.v102.tuvl.de/alua/
create standby tag=1
set alua alua_access_state=2
# Assign one LUn the standby alua group:
cd /iscsi/iqn.2013-03.de.tuvl.v102.storage:shared-01.v102.tuvl.de/tpg2/luns/lun10
set alua alua_tg_pt_gp_name=standby
Afterwards it looks like that:
/> ls

The ESX server reflects the same. I found no documentation on this, is
there any?
Cheers,
Thomas
