RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
iscsid do not login automatically on discovered portals after reboot.

Version-Release number of selected component (if applicable):

iscsi-initiator-utils-6.2.0.872-18.el7.x86_64

uname -r
3.6.0-0.28.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Discovery portals
iscsiadm -m discovery -t st -p "na3170b.lab.bos.redhat.com" -I default  -P1
Target: iqn.1992-08.com.netapp:sn.151753773
	Portal: 10.16.41.222:3260,1
		Iface Name: default
	Portal: 10.16.43.127:3260,1
		Iface Name: default

2.Login to portals
iscsiadm -m node -l
Logging in to [iface: default, target: iqn.1992-08.com.netapp:sn.151753773, portal: 10.16.41.222,3260] (multiple)

3.reboot

4. check sessions after reboot
iscsiadm -m session
iscsiadm: No active sessions.

5. Manual login works
iscsiadm -m node -l

Expected results:
sessions should be restored after reboot

Comment 4 Bruno Goncalves 2013-03-19 15:25:19 UTC 
Problem is still reproducible with:

rpm -q iscsi-initiator-utils
iscsi-initiator-utils-6.2.0.873-2.el7.x86_64

uname -r
3.7.0-0.36.el7.x86_64
Comment 5 Marian Csontos 2013-04-18 17:44:19 UTC 
There is a problem with systemd dependencies at boot: iscsi is started before network.

So I tried restarting iscsid later after boot but session is still not restored.

`iscsiadm -m node -l` works for me. Adding the line to rc.local.
Comment 6 Peter Rajnoha 2013-04-19 06:53:54 UTC 
There's also a note in the /etc/init.d/iscsi init script:

# Note we should have $network in Required-Start/Stop but we don't because if
# we would require network chkconfig will put us directly after NetworkManager
# when using NM, which will make our see if the network is up test succeed
# while NM is actually still configuring the network. By not requiring network
# chkconfig will use the chkconfig header to determine our start prio, starting
# us after the old network service, but before NM (netfs does this the same).

(adding Required-Start: $network iff using network.service instead of NetworkManager.service should solve the issue)

*** Bug 958864 has been marked as a duplicate of this bug. ***
Comment 8 michal novacek 2013-05-02 15:02:19 UTC 
Is there any plan on how to solve this permanently with for example systemctl.service with proper dependencies?
Comment 10 Chris Leech 2013-06-20 20:20:17 UTC 
This should be fixed with iscsi-initiator-utils-6.2.0.873-7, which is in sync with f19 and has proper systemd unit files.
Comment 11 Bruno Goncalves 2013-06-21 11:36:20 UTC 
The problem continues on RHEL7.

Comment 12 Bruno Goncalves 2013-06-21 11:53:33 UTC 
Okay seems the culprit now is selinux.

Making it permissive the sessions start after reboot.

> Okay seems the culprit now is selinux.

What is the version of selinux-policy installed?
That should be fixed as of 3.12.1-51.
Comment 14 Bruno Goncalves 2013-06-21 15:22:51 UTC 
Thank you, I was using selinux-policy-3.12.1-48.el7

With selinux-policy-3.12.1-52.el7 it seems to work.
Comment 15 Bruno Goncalves 2013-07-09 13:17:44 UTC 
It has been fixed on

iscsi-initiator-utils-6.2.0.873-7.el7.x86_64

selinux-policy-3.12.1-59.el7.noarch

Comment 18 Michael Watters 2018-08-07 18:07:57 UTC 
I'm still seeing this issue on RHEL (CentOS) 7.5.  The system has selinux-policy-3.13.1-192.el7_5.4.noarch and iscsi-initiator-utils-6.2.0.874-7.el7.x86_64 installed. 

After reboot only one iscsi target is logged in to despite node.startup being set to automatic for all nodes.

Comment 19 Sudha Sundaram 2020-02-07 18:48:27 UTC 
I am seeing this problem on Red Hat Enterprise Linux Server release 7.6 (Maipo)
Kernel Version: 3.10.0-957.12.2.el7.x86_64
running on VMWare

Was logged into target before a reboot. After reboot, see the following messages:

Feb 06 17:51:25 MD161-3033-04 iscsiadm[23980]: iscsiadm: No matching sessions found
Feb 06 17:51:25 MD161-3033-04 iscsid[21592]: iscsid shutting down.

The very first time after a reboot does not work.
As a workaround,  Once i do "iscsiadm --mode node --targetname iqn.1992-08.com.netapp:sn.26fa40d9362a11ea8c28005056b3aea6:vs.5 --login" it starts working thereafter.

Comment 21 Bhavuk Taneja 2020-09-08 02:27:37 UTC 
I believe I came across this issue on this node:

Its cluster node is not showing this issue, and its running on different version of selinux-policy:

Have not tried to update "selinux-policy" yet and reboot the server. Will share the results as the case progresses.
