targetcli saveconfig fails after install

[LnxGnome]

New/fresh install of 16.04 server. (Ubuntu 16.04 LTS)

disable qlini_mode on qla2xxx, mkinitramfs, reboot

Enter targetcli and configure a FC LUN.

saveconfig fails with....
  ConfigError: Unknown value type 'qla2xxx_wwn' when validating <WWPN>

Can exit targetcli and re-enter with config intact (running), but cannot save the config (will not survive a reboot).

Testing with patch from: https://github.com/bootc/rtslib/commit/727c345bd18137c424e4fba62bfab7bcfabfc024
Save config did not produce error. Will reboot to see if config is save/valid.

[LnxGnome (78luphr0rnk2nuqimstywepozxn-launchpad)]

Patch from https://github.com/bootc/rtslib/commit/727c345bd18137c424e4fba62bfab7bcfabfc024 'works for me'. Config is saved and active after a reboot.

[LnxGnome (78luphr0rnk2nuqimstywepozxn-launchpad)]

Expectation: For the package maintainer to apply the patch to Ubuntu package for testing and eventual roll into release.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Markus (moswald)]

Can confirm - got hit by that bug and the patch worked for me as well.

[Florian Schönbeck (schoenbeck)]

Same problem here.

Saving configuration works after applying patch to /usr/share/pyshared/rtslib/config.py and /usr/share/pyshared/rtslib/utils.py
