How to delete iscsi target from initiator? How to remove inactive iscsi target? Remove iscsi storage target from initiator? Remove iscsi virtual disk on CentOS / RHEL 7 Linux.
In my earlier article I shared a step by step guide to configure iscsi target and initiator to setup a multipath SAN storage using your CentOS / RHEL 7 Linux machine. In the same article I had given brief steps to remove or delete iscsi target. Anyhow here I will share the steps to delete iscsi target on CentOS / RHEL 7 Linux in detail.
Steps to delete iscsi target
- Remove iscsci entry from
- Un-mount the iscsi disk
- Disconnect the iscsi disk from that target
- Delete the connection
- Go have a beer (if you drink one)
Firstly make sure you remove the iscsi entry from
/etc/fstab of the target you wish to remove.
Assuming you wish to remove the iscsi target visible as
/dev/sdc from our last article. Get the UUID of
blkid as shown in the below example
# blkid /dev/sdc /dev/sdc: UUID="f87DLO-DXDO-jjJ5-3vgO-RfCE-oOCA-VGploa" TYPE="LVM2_member"
Here UUID for
f87DLO-DXDO-jjJ5-3vgO-RfCE-oOCA-VGploa. So look out for this UUID in
/etc/fstab and remove that entry.
Un-mount the disk
Now it is time to un-mount your disk before we go ahead with deleting the target. You can manually unmount the disk using
# umount /mount_point
/dev/sdc was mounted on
/clusterfs as was on our last example, we can unmount the disk by using
# umount /clusterfs
Disconnect the iscsi disk from that target
If you need an iSCSI connection not to be restored after reboot, you first have to log out to disconnect the actual session by using below command
[root@node1 ~]# iscsiadm --mode node --targetname iqn.2018-12.com.example:servers --portal 10.0.2.13 -u Logging out of session [sid: 1, target: iqn.2018-12.com.example:servers, portal: 10.0.2.13,3260] Logout of [sid: 1, target: iqn.2018-12.com.example:servers, portal: 10.0.2.13,3260] successful.
Repeat this command for every iscsi target you wish to remove/delete.
Delete the connection
Now is the time to delete your iscsi target connection on the initiator node.
# iscsiadm --mode node --targetname iqn.2018-03.com.golinuxcloud:tgt1 --portal 10.0.2.13 -o delete
Similarly repeat this command for every iscsi target which you wish to delete.
Stop the iscsi service (optional)
If you have deleted all the iscsi targets from your setup then you do not any additional daemon running on your initiator node.
So you can stop the
# systemctl stop iscsid # systemctl disable iscsid
If you are deleting only some of the iscsi target, and others are still connected then do not disable or stop this service.
So all good, time to have a beer.
Lastly I hope the steps from the article to delete iscsi target on RHEL/CentOS 7 Linux was helpful. So, let me know your suggestions and feedback using the comment section.
