I have an appliance that does email archiving and it is using a volume 
on the Equallogic to store data. I can't only have the data in one place 
though so I'm mounting the partition (ext3) from a local linux server 
and using duplicity to back the data up to a remote location over FTPS. 
The linux server isn't writing anything to the partition, only reading 
from it.

Do you have a NIC that is on the same subnet as the array or are you

NICs on the same subnet is the preferred way.

Hey Don, I did finally get it connected. The reason I don't need mpio is 
because I'm just connecting to this volume to run backups with 
Duplicity. Performance and redundancy isn't really a big deal and I only 
have one link connected to that linux box at this time anyway. How do I 
get around the startup script issues connecting on boot?


Thanks!

I have an EqualLogic and it works pretty well.

I typically specify the target with -T, and the grapdmin user console
shows errors too (if the initator is connect to a good IP).

Is it timing out or failing right away?

Can you double check that the target portal IP is correct?  Maybe try
defining the target as "unrestricted" to make sure it isn't a password
kind of problem.

Mark



Hey Mark, sorry for the delayed response. I finally got it connected 
after deleting all of my discovery information and starting from 
scratch. I wasn't able to get it connected using CHAP so I just 
restricted it based on IP address. I'm using the latest firmware on the 
PS6100XV as of last week. Since getting it connected I haven't had any 
issues.


Kind regards,

Send the /var/log/messages, iscsid.conf and output of

iscsiadm -m node -T youtarget


for the target you are trying to log into. That error indicates you
probably messed up on the CHAP setup or initiator ACL type of setup.

Hello,

 What version of FW is on the EQL array?   Any error messages on the EQL
array events?

 I work for Dell/Equallogic and I have no issues connecting up ubuntu 12.10
to EQL.The only recent issue I've seen with 12.x is 12.04 the startup
scripts don't login to iSCSI after a reboot or on start up.

I'm curious why you don't want MPIO?

You'll need to modify /etc/sysctl.conf for MPIO

# ARP connection mods

net.ipv4.conf.all.arp_ignore=1
net.ipv4.conf.all.arp_announce=2
net.ipv4.conf.all.rp_filter=2


For ACLs I typically use the initiator name from the ubuntu server.   I.e.
iqn.1993-08.org.debian:01:8ab9cf5340f0

Have you opened a case with Dell?While not a 'supported' OS, we will do
best effort to assist you.

 Can you dump the following?

$sudo iscsiadm -m node

$sudo iscsiadm -m session

$sudo iscsiadm -m iface

$sudo iscsiadm -m discovery

Do you have a NIC that is on the same subnet as the array or are you
routing to the SAN?

NICs on the same subnet is the preferred way.

Regards,

Don
