Hey Guys, You have to just use this following command:
iscsiadm -m node --targetname "iqn.2001-04.com.example:storage.lun1" --portal "192.168.0.101:3260" –logout and again use your command as follows: iscsiadm -m node --targetname "iqn.2001-04.com.example:storage.lun1" --portal "192.168.0.101:3260" –login actually you are allready login so that’s a reason , it shows the error ( "initiator reported error (15 - already exists)") Cheers..............
