targetmgr

Wrapper for rtslib developed and used by IT Services Group of the Physics Department at ETH Zurich to manage our iSCSI targets.

Testet and works with Ubuntu Xenial 16.04

Further documentation:

- rtslib:  http://linux-iscsi.org/Doc/rtslib/html/

Reads the configuration from ./targetmgr.json and creates the corresonding iSCSI targets.
