IPv4/IPv6 initiator-target--automatic mapping of targets
Hello All, I have a case where both initiator and target are configured with IPv4 and IPv6 address. The target listens ob both sockets. When i login to the target without mentioning the portal , it logins and creates two sessions for the same target. Questions 1.How to force the initiator to login with a specific IP version ? It is configured for automatic login and both systems have to retain dual ip address version. 2.The session id always get incremented after each new login. Can this be changed to reset /start from least available after for each new session ? 3. How to persistently map iscsi target to fixed sdX id ? for third Question, I came across couple of threads in forum and IET for similar issue. I am trying to configure the ScsiId in the ietd.conf and create the udev rule on the initiator. But no success. == Ietd.conf== Target iqn.2008-03.storageserver:storage.target1 Lun 1 Path=/dev/VolGroup00/target1,Type=blockio,ScsiId=1234567 Initiator Udev rule and ScsiId === [EMAIL PROTECTED] rules.d]$ sudo scsi_id -g -s /block/sdc 1494554003736353433323100 [EMAIL PROTECTED] rules.d]$ cat 20-names.rules KERNEL=sd*, BUS=scsi, PROGRAM=/sbin/scsi_id, RESULT=1234567, NAME=sdb%n [EMAIL PROTECTED] rules.d]$ sudo iscsiadm --version iscsiadm version 2.0-865 === Once, I am successful with a single system,it has to be replicated on other systems. Is there feature in consideration on future initiator software releases to extract this info and provide a option to automate this event ? thanks in advance for your time and suggestions Regards Padmanabhan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups open-iscsi group.

Re: [PATCH] Fix indentation
Erez Zilber wrote: Mike Christie wrote: Erez Zilber wrote: Fix indentation and remove trailing spaces. Signed-off-by: Erez Zilber [EMAIL PROTECTED] Mike? Are you ok with this patch? It is already broken. Did you run a script for this? Could you send the script? Then when I merge Eli's patch I can just run the script and you do not have to worry about the breakage? The kernel modules in the open-iscsi.git tree are also different from upstream and the bnx2i tree, so a script that I can run against them would make it easier for use to sync up, unless you want to send patches for those messes. I have a script that finds indentation problems (attached). It doesn't fix them, but that should be really easy to do. Mike, Were you able to use it?

[PATCH] fix host number sysfs parsing
I need this on top of git head to be able to get status
from iscsi using 2.6.25-rc1. You'll probably want
to go looking for host in both sysfs paths, to handle
old and new kernels. Here's an example of how it works
in a recent one.
Others testing recent kernels may want to hack this
in temporarily.
Here are the error message from old iscsi utils,
iscsi-initiator-utils-6.2.0.868-0.3.fc9.x86_64.
aib01# iscsiadm -m session
iscsiadm: Could not get host for sid 1.
iscsiadm: could not get host_no for session 6.
iscsiadm: could not find session info for session1
iscsiadm: Can not get list of active sessions (6)
aib01# iscsiadm -m node -p 10.100.2.32,3260 -T aib02 -u
iscsiadm: Could not get host for sid 1.
iscsiadm: could not get host_no for session 6.
iscsiadm: could not find session info for session1
-- Pete
Sysfs layout changed yet again. Accommodate new kernels (2.6.25-rc1
at least), but probably break the parsing on older ones.
