It may be necessary to edit this node object to remove specific IPs from its listings without modifying the node itself if a customer has changed the IP of their ISCSI targets but the IQN remains valid. iscsiadm -m discoverydb -t sendtargets -p : -o deleteįinally, it is necessary to check the file system to ensure Linux does not try to re-establish the connection on future boot operations. If required, you can also delete the targets from the ISCSI discovery database entirely. Once this is complete, make sure the session is no longer listed: iscsiadm -m session To prevent the session from re-establishing, you may wish to remove the node: iscsiadm -m node -o delete -T Do so by providing the file system's mount point. Note that there is no 'n' between the 'u' and the 'm'-the command is umount and not 'unmount.' You must tell umount which file system you are unmounting. When run, the command should look something like this: iscsiadm -m node -T :UNI.target-25a74d1 -p 10.10.10.10:3260 -u To unmount a mounted file system, use the umount command. Kill an ISCSI session: iscsiadm -m node -T -p : -u

The OS password may differ from the password used to access the User Interface. Note: Ensure you have the OS password to access the Unitrends system’s command line. Use an SSH client such as PuTTY to access the Unitrends system at the command line level. Session connected from :aa1ab4ad66df 127.0.0.1Ī customer may also see iscsid errors on the console screen at boot time indicating connection attempts to a particular iscsi target are failing, which may lead to delayed boot time. Ensure that no iSCSI initiator is connected to the target. When trying to remove the session, you may receive an error message like:įailed to destroy the image: tgtadm: this access control rule does not existĬould not delete iSCSI target 7. In order to prevent the Unitrends appliance from reconnecting to these sessions, these commands may be necessary. Under certain circumstances, an ISCSI session may persist even after it has been removed from the storage menu of the Unitrends appliance. Necessary commands to remove an ISCSI session ISSUE
And then, after proper unmounting, the best way to unplug a USB external hard-drive is: udisksctl power-off -b /dev/sdb. So first, you eject /dev/sdb (or umount everything). Remove ISCSI sessions using the Linux command line On Linux, eject will work, but will not really 'finish the job' regarding USB rotating drives.
