There are 8 targets on my device, only want to connect to 1, but it is trying to connect to all 8, how can I tell it which target to log into?

Quick WARNING:
setting node.startup = automatic will make it automatically connect to ALL DISCOVERED TARGETS on the portal!

For me, this was all 10 targets that were in production use! eeek!

Here’s what the manual says: (via http://www.open-iscsi.org/docs/README)
To automate login to a node, use the following with the record ID
(record ID is the targetname and portal) of the node discovered in the
discovery above:
iscsiadm -m node -T targetname -p ip:port –op update -n node.conn[0].startup -v automatic

restarting iscsi wasn’t naccassary.

Not tested reboot yet, but i see some configuration files automagically appeared in /etc/iscsi/nodes/ so I guess it should work. Eventually I will need to change node.startup = manual to node.startup = automatic, and of course put something into /etc/fstab :)

IPv6 works without problem.

PS. Generally you do not need to partition disk. One can create filesystem directly on disk, or put there other things (luks encryption, LVM, raid between multiple iscsi targets, etc) . It is even recomended sometimes i.e for btrfs, or zfs, or when sector aligment can be problematic. It is also not needed if exported block device is already a partition of some block device. Partitioning in such situations is possible of course, but not needed.

Is there anyway to load in the Initiator the new LUNs recently created in the Target ?
The ‘open-iscsi restart’ doest the job, but not perfectly. When I restart the ‘open-iscsi’ I lost access to the the others LUNs that i was using before.

Can’t I just reload/update without loosing access to the LUNs already in use ?

Thanks.

I have three targets setup on my device but I only want my (debian) client to connect to one of them, when I restart the service however it attempts to login into all three and takes ages because the credentials are wrong for two of them.

How do I specify which target to login to?

pbarker@eccles:~$ sudo blkid /dev/sda1
/dev/sda1: UUID=”1abd1d95-8926-49f6-817b-482f02f6c6cc” SEC_TYPE=”ext2″ TYPE=”ext3″
pbarker@eccles:~$ grep 1abd1d95-8926-49f6-817b-482f02f6c6cc /etc/fstab
UUID=1abd1d95-8926-49f6-817b-482f02f6c6cc / ext3 relatime,errors=remount-ro 0 1
pbarker@eccles:~$

Well I managed to get a step further, but now I get the error below when I try to restart the iscsi service:

* Starting iSCSI initiator service iscsid grep: /etc/iscsi/initiatorname.iscsi: Permission denied
* Error: /etc/iscsi/initiatorname.iscsi does not contain a valid InitiatorName.
* The iSCSI driver has not been correctly installed and cannot start.

Has anyone encountered this or know how to configure it correctly?

Thanks

I am trying to get my Networked DVD drive which is part of my NAS to work with my Ubuntu setup using an iscsi initiator. I have it working on Windows XP and Windows 7, now I am trying to get it working on Ubuntu. I will then have all computers on my network using one DVD drive.

I tried the instructions above but when I try to save the iscsid.conf file I get the message:

[ Error writing /etc/iscsi/iscsid.conf: Permission denied ]

Is there a way around this? Or does anyone know how to get iscsi to work with a networked DVD drive?

Any help would be appreciated.

Except…my target changes between /dev/sdc1 and /dev/sdd1 between reboots and is appears to be a random choice.

Is there anyway to “lock” the target to the same /dev node so I can put it in my fstab to mount on boot up?

Cheers!
