I have Googled but did not find anything. I decided to downgrade the package, but that does not seem to be possible. [root@controller ~]# yum downgrade targetcli Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: ftp.nluug.nl * epel: ftp.nluug.nl * extras: ftp.nluug.nl * updates: ftp.nluug.nl Nothing to do Now I am really worried because I cannot access the iSCSI target anymore. How to fix the issue or downgrade the package so I can access the iSCSI again?
