Re: iscsi connection error
Hi Mike, First my apologies for a late reply. I have resolved this issue. I changed the install locations and it worked. Earlier i tried shared home install. Basically, i had a shared oracle home and tried to install the oracle software (binaries) to be shared by both nodes. But later i installed the oracle softwares separate on both the nodes and they worked fine. Appreciate your sincere efforts to help noobs like me.

Re: open-iscsi initiator machine hangs when iscsitarget is rebooted
@Ulrich, Were you exporting something on ocfs using the iscsi-target? If you had meant any data transfer between the boxes using iscsi-target, there were no data transfers between them. I tried the suggestion you gave me. It works perfect. Once i stopped the service, it says connect failed(111) and keeps trying and once the service is up, the error goes off and it says connection 1 is operational after 10 attempts. The same case with the iscsitarget/initiator box reboot as well.

On the open-iscsi initiator i had opened a terminal with command tail -f /var/log/messages and left it running And then i rebooted the server with iscsitarget/open-iscsi initiator And all i could see were ocfs2_dlm node 0 leaves domain nodes in domain : 1 and then it hangs again so i had to manually hard reset the server I tried to boot with runlevel 2 but there were not much of a use because there were no specific error messages to this scenario, i Checked /var/log/messages and /var/log/boot.omsg But i'm still able to ping the open-iscsi initiator system on its hang. But when i try to rsh or ssh to the system, nothing happens. I haven't setup multipath yet. @mike I have setup ocfs2 file system on a partition(on secondary hard drive on iscsitarget/open-iscsi initiator box) which is being mounted as /u01/orcl on both boxes. So i think i have nbd(not sure if my setup is supposed to be called as nbd). nbd is a special network block device driver. Do not worry about it. It does not look like you have it. When i tried rciscsitarget stop on iscsitarget/open-iscsi initiator box, both the iscsitarget/open-iscsi initiator box and open-iscsi initiator box hanged. Again a hard reset. Were you exporting something on ocfs using the iscsi-target? Could you simplify this and take ocfs out for a minute. Just add some file or real disk or a virtual disk to the ietd.conf file for the lun. For example just stick: Lun 0 Type=nullio,Sectors=2097152 in the ietd.conf which will create a dummy lun. Then restart the target and log in from the other box and retry your reboot test with that (no ocfcs2 at all). Does that hang? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups open-iscsi group.

open-iscsi initiator machine hangs when iscsitarget is rebooted
Hi member, I run a test environment with 2 servers running opensuse 11.1(one has iscsitarget/open-iscsi initiator and other has open-iscsi initiator). Usually, I shutdown the open-iscsi initiator server first and then the other server with iscsitarget/open-iscsi initiator. But whenever i reboot the server with iscsitarget/open-iscsi initiator, the other server with open-iscsi initiator hangs completely even after the server with iscsitarget/open-iscsi initiator comes back after a reboot. Is this a normal behaviour? Because of the server hang, i'm unable to check the logs and always have to go for a hard reset/shutdown. noob. help pls. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups open-iscsi group.

Re: open-iscsi does not detect logical volume
Hi All, I have figured out what the problem is: On reboot i found out that the volume group becomes inactive. So i did a vgchange -a y and it becomes active and restart both iscsitarget and open-iscsi services and you are good to go. Many Thanks to mike and Konrad for helping me out. I haven't yet figured out as to why the volume group goes inactive on reboot and how to automate this process of activating it on reboot. Thanks to one and all who helped me resolve this issue. I believe this is an issue with opensuse.

Re: open-iscsi created only one disk but missing 2 more
Hi, Please find my answers below: Appreciate you help. What Target are you using? both the systems are ubuntu 8.10 I beat my head on a issue when I first setup regarding access permissions. If you don't have the permissions right on the array, open-iscsi will let you see it but not log in. I 'm logged in as root and have executed all the commands. When you say array, fyi it is just a secondary hard drive conencted to the system. Another thing you may want to check, if you are sharing luns between systems, some arrays require you to explicitly allow that behavior. Is there a command for that? how do i check if i need to explicitly allow sharing? And last but not least, if you have a backend and a front end connection make sure you are connecting to the array with the right interface. Make sure one connection does not have a matching MTU *jumbo frames with the array it can cause strange behavior. I'm sorry i 'm unable to understand this(if you could elaborate on this pls: newbie). But to make things simple, my scenario is as follows: Home pcs(900Mhz/512MB RAM/P3): 2 systems with ubuntu 8.10 with both open-iscsi installed. On System 1 : i attached a second hard drive of size 20G. I installed lvm2 and I created 1 physical volume of size 20G, 1 volume group vg1 and then created 3 logical volumes /dev/vg1/asm 17G, /dev/vg1/ocr 960M and /dev/vg1/vote 750M. On System 2: executed commands: iscsiadm -m discovery -t st -p 192.168.20.22 The output was: 192.168.20.22:3260,1 iqn.2001-04.com.ubuntu:scsi.disk.vg.asm 192.168.20.22:3260,1 iqn.2001-04.com.ubuntu:scsi.disk.vg.ocr 192.168.20.22:3260,1 iqn.2001-04.com.ubuntu:scsi.disk.vg.vote iscsiadm -m node -T iqn.2001-04.com.ubuntu:scsi.disk.vg.asm -p 192.168.20.22 -l Output: Login session [iface: default, target: iqn.2001-04.com.ubuntu:scsi.disk.vg.asm, portal: 192.168.20.22,3260] iscsiadm -m node -T iqn.2001-04.com.ubuntu:scsi.disk.vg.vote -p 192.168.20.22 -l Output: Login session [iface: default, target: iqn.2001-04.com.ubuntu:scsi.disk.vg.vote, portal: 192.168.20.22,3260] iscsiadm -m node -T iqn.2001-04.com.ubuntu:scsi.disk.vg.ocr -p 192.168.20.22 -l Output: Login session [iface: default, target: iqn.2001-04.com.ubuntu:scsi.disk.vg.ocr, portal: 192.168.20.22,3260] I must really thank you for having replied me.

Re: open-iscsi created only one disk but missing 2 more
Thanks for your reply. But i might sound a little stupid to ask this: A very basic question: The hard disks i 'm using is ATA. I believe that open-iscsi works on scsi devices.

Re: open-iscsi created only one disk but missing 2 more
kernel: 2.6.27-11 IET is your target. To my understanding IET is iscsi enterprise target which is similar to open-iscsi in implementing iscsi targets. open-iscsi and IET are different organisations implementing iscsi. Am i right?
