Hello people,
Ik have a little problem, i'm working on a Red Hat Enterprise Linux Server release 6.5 (Santiago)system (for a storage exam) and i need to connect to a iscsi lun on a NetApp filer (Ontap 8.3).
The Lun was on a older system and for the exam i had to move it to the new storage system. No problem there. The IP of the iSCSI target is not changed, and on the new storage i setup the name of the target the same as the old
When moved i did the following
iscsiadm -m session
iscsiadm -m discovery -t sendtargets -p 10.10.10.18
iscsiadm -m node -T iqn.1992-08.com.netapp:sn.123456789 -p 10.10.10.18:3260 -l
after that i rebooted the linux server
when up again i gave the command: mount to see if all drive where there, but the lun which is /dev/sdb what not there
then i did mount -a
but i got the message /dev/sdb already mounted or /NetApp/Lun busy
i looked in the fstab file (which has not changed)

if i close all sessions, reboot the server the same message is there aleardy mounted ......
i'm at a loss on how to get rid of this message and reconnect to the iSCSI lun, any help for this linux newbe would be helpfull.
