Description Oneata Mircea Teodor 2018-04-11 14:17:22 UTC 
This bug has been copied from bug #1563644 and has been proposed to be backported to 7.5 z-stream (EUS).
Comment 4 Sweta Anandpara 2018-05-04 11:50:32 UTC 
Validated on a RHGS cluster having the build python-rtslib-2.1.fb63-11.el7.noarch.

Created 2 blocks, saved the configuration, moved the file to a local location (say, /home), cleared the targetcli configuration, and restored it from the saved file. Verified that the blocks initially created were correctly shown in targetcli ls output. Again saved the configuration of targetcli and executed a diff of '/etc/target/saveconfig.json' with the originally saved file in /home. They were the same. 

I do see the below errors while restoring the config, and Prasanna (developer) says they are to be noted and not to be worried for, at the moment. 
[root@dhcp47-65 ~]# targetcli restoreconfig /home/saveconfig.json 
Configuration restored, 4 recoverable errors:
Storage Object user/ob2: Cannot set attribute dev_size: [Errno 95] Operation not supported, skipped
Storage Object user/ob2: Cannot set attribute qfull_time_out: [Errno 22] Invalid argument, skipped
Storage Object user/ob1: Cannot set attribute dev_size: [Errno 95] Operation not supported, skipped
Storage Object user/ob1: Cannot set attribute qfull_time_out: [Errno 22] Invalid argument, skipped

This is good for the validation of the patch that has gone in in this bug. Please feel free to move this bug to verified after a round of regressions. Thanks!
