So what you run this command only one session is made sometimes?

What is the output of the login command when it fails to create one of
the sessions?

Hi ,

Current setup is:

(LOM of Intel i350 and NIC of intel corporation 82580 on IBM x3650M4 Server with RHEL6.1)also i installed the software of multipathing.

The issue is:

iSCSI session shows random behaviour ,some time only one of the session made via LOM and NIC card retain and sometimes both retain after system reboot

following are some of the settings of /etc/iscsi/iscsid.conf file
node.startup = automatic
node.session.timeo.replacement_timeout = 30

i created the session by following the below mention steps:

#iscsiadm -m iface -I <iface_name> --op=new

#iscsiadm -m iface -I <iface_name> --op=update -n iface.hwaddress -v <hardware address>

hardware address of particular ethX to which i want to bind the iface

#iscsiadm -m discovery -t st -p <portal_address> -I <iface_name> -P 1 

e.g of portal address: 192.168.3.4:3260

#iscsiadm -m node -I <iface_name> -p <portal_address> -l

and i check the session via following command

#iscsiadm -m session

- Can anybody help me in solving this issue .i.e why session show random behaviour .what should i do to overcome this problem i.e Is i have to do some more setting so that the iscsi sessions will retain after system reboot too.
-Is there any particular file in Linux file system to see the iSCSI related logs. or is there any command to debug.
