Help debugging connection1:0: detected conn error (1011)
Hi, I am running an initiator on FC9 64-bit (Linux 2.6.27.21-78.2.41.fc9.x86_64 #1 SMP) connecting to a NexSan SATA boy over 1GB ethernet with iSCSI. I am running open-iscsi 2.0-870. When I try to connect I get a conn error (1011) and I am struggling to know where to go next. The NexSan has no errors. Can someone give me pointer on where to go next to try and get this working. I have another machine running FC8 32-bit (Linux 2.6.26.8-57.fc8 #1 SMP) and that works just fine.

Re: Help debugging connection1:0: detected conn error (1011)
I downloaded and compiled the open-iscsi release, so I think I am using that. However, just to be sure I uninstalled iscsi-initiator-utils (yum remove ) so I only have open-scsi. Now, when I try to start iscsid ( ./iscsid -f ) I get the following: iscsid: Missing or Invalid version from /sys/module/ scsi_transport_iscsi/version. Make sure a up to date scsi_transport_iscsi module is loaded and a up todate version of iscsid is running. Exiting... I will investigate that. Any hints?

You need to load the iscsi modules. modprobe iscsi_tcp You probably were using the iscsi-initiator-utils tools. With them you do have done: service iscsi start with open-iscsi.org tools you do service open-iscsi start if you were using the init scripts. The init scripts do the modprbe and iscsid, so if you start iscsid by hand you have to do the modprobe too. You might have a weird mix. Do a whereis iscsid and whereis iscsiadm and whereis iscsistart remove them. Then just do yum install iscsi-initiator-utils. That should give you the current F9 tools, which should work. I will investigate that. Any hints?

Re: Help debugging connection1:0: detected conn error (1011)
Just looked at the trace myself. I can see it trying to contact LUN 00 but I do not have that configured on my target. I am using LUN 01 That is why is it failing. When I change my Target LUN to 00 it works. So, how or where is the initiator deciding on the LUN? Is it configured or should it find it from the Target? Thanks for your help so far, I feel I am getting somewhere now! On May 8, 6:27 pm, hissing_sid dopey...@gmail.com wrote: I have a dump. How should I get it to you?

Is it The scsi layer will send a inquiry to lun0 to get some info about the target and start off the device discovery process. It would then normally send a report luns command to discover all the devices. Your target might be operating as expected and need some special flags in the scsi layer. Attach your trace to here http://groups-beta.google.com/group/open-iscsi/files so we can see what is going on. configured or should it find it from the Target?
