Re: Broadcom NIC sessions not retaining on reboot (node.startup=automatic not working)

Hi 

set node.startup = manual in 
iscsid.conf then run iscsiadm to turn on specific portals by setting the 
--value/-v to automatic.
 

Thanks and regards

Dear All

I have connected my host and iSCSI storage directly with LAN cable.

The iface created for the particular port through which the connection is made is:

 iscsiadm -m iface -I bnx2i.3c:d9:2b:f5:2e:e7
# BEGIN RECORD 2.0-872
iface.iscsi_ifacename = bnx2i.3c:d9:2b:f5:2e:e7
iface.net_ifacename = <empty>
iface.ipaddress = 192.168.3.20
iface.hwaddress = 3c:d9:2b:f5:2e:e7
iface.transport_name = bnx2i
iface.initiatorname = <empty>
# END RECORD

I have successfully discovered the target using the command:
iscsiadm -m discovery -t st -p 192.168.3.14:3260 -I bnx2i.3c:d9:2b:f5:2e:e7

And logged into my storage successfully as:
iscsiadm -m node -p 192.168.3.14:3260 -I bnx2i.3c:d9:2b:f5:2e:e7 -l

I can then see my sessions successfully as:
iscsiadm -m session
bnx2i: [2] 192.168.3.14:3260,1 iqn.2001-03.jp.nec:storage01:ist-m000-sn-0000000000090019.lx-hprhel6.target0000

I have the setting node.startup = automatic
in the file /etc/iscsi/iscsid.conf

But on reboot I see:
iscsiadm -m session
iscsiadm: No active sessions.

I think the node.startup=automatic is not working. Have any of you faced such a problem. Please help.

Just wanted to add some more details.

The iscsi/iscsid service does not go by the iscsid.conf settings alone.
When you discovery/setup targets it uses those as the defaults for the
records that get made. If you run

iscsiadm -m node -T youtarget -p ip -I iface

then you will see the settings that will get used for that specific records.

If those also have automatic, then check that the iscsid and iscsi
services are started at boot (in some distros it might be called
open-iscsi).

And to set settings for specific records run:

iscsiadm -m node -T youtarget -p ip -I iface -o update -n nameofsetting
-v newvalue

It is also possible that the corresponding nic interface is up on boot.
It's worthwhile to make sure that the ONBOOT=yes is set inside that
corresponding sysconfig network script.

Hi Vaibhav,

Thank you so much. I did the settings as you suggested and it worked :)

In case someone faces the same situation i.e. Broadcom sessions not retaining on reboot, you can proceed as:

Step 1. Do discovery as: iscsiadm -m discovery -t st -p <IP>:port -I <iface>
Step 2. Set node.startup = manual in iscsid.conf, and then run iscsiadm to do the setting on each specific portal as:
            iscsiadm -m node -p <ip>:port -I <iface> -o update -n node.startup -v automatic
Step 3. Then login as:
            iscsiadm -m node -I <iface> -p <ip>:port -l
