Python library for configuring the Linux kernel-based multiprotocol SCSI target (LIO)

A Python object API for managing the Linux LIO kernel target

rtslib-fb is an object-based Python library for configuring the LIO generic SCSI target, present in 3.x Linux kernel versions.

It supports both Python 2 and Python 3, thanks to the python-six library.

FB 的 "Free branch"

　　rtslib-fb is a fork of the "rtslib" code written by RisingTide Systems. The "-fb" differentiates between the original and this version. Please ensure to use either all "fb" versions of the targetcli components -- targetcli, rtslib, and configshell, or stick with all non-fb versions, since they are no longer strictly compatible.

rpm 版本:

　　rtslib-fb-2.1.51-1.noarch

命令：

　　/usr/bin/targetctl

syntax: /usr/bin/targetctl save [file_to_save_to]
        /usr/bin/targetctl restore [file_to_restore_from]
        /usr/bin/targetctl clear
  default file is: /etc/target/saveconfig.json
