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.

RH7.6 OS boot logs

Description of problem:
In iSCSI offload Boot from SAN environment with multipath configuration, during OS boot
the iscsistart unnecessarily attempts to login to already logged in sessions thus causing delay in system boot.
 
Version-Release number of selected component (if applicable):
RHEL 7.6 GA

How reproducible:
Always 100% reproducible

Steps to Reproduce:
1. Install RHEL 7.6 GA OS on iSCSI LUN using QLogic Fastlinq CNA adapter via iSCSI offload path in mutipath configuration.
2. The OS installs successfully
3. On the first OS boot it is observed that iscsistart continuously attempts login to iSCSI sessions already being established.

[   81.531880] dracut-initqueue[2342]: iscsistart: version 6.2.0.874-10
[   82.535366] dracut-initqueue[2342]: iscsistart: initiator reported error (15 - session exists)
[   82.540439] dracut-initqueue[2342]: iscsistart: initiator reported error (15 - session exists)
[   82.545569] dracut-initqueue[2342]: Warning: 'iscsistart -b ' failed with return code 0

4. This adds delay in booting of OS.

Actual results:
The OS boot takes more than 5 mins to boot.

Expected results:
The OS should boot within less than 5 mins.

Additional info:
Adding OS boot logs showing multiple login attempts.

Below are the multipath.conf settings,
cat /etc/multipath.conf
defaults {
        find_multipaths yes
        user_friendly_names yes
        polling_interval 5
        fast_io_fail_tmo 5
        dev_loss_tmo 10
        checker_timeout 15
        failback immediate
}
Comment 3 Nilesh Javali (Marvell) 2019-08-12 12:29:01 UTC 
Chris,
We are seeing this issue in RHEL 8.0 as well.
However looking at the iscsiroot.sh script (/usr/lib/dracut/modules.d/95iscsi/) the method to initiate login to iSCSI target has changed from "iscsistart -b" to "iscsiadm -m fw -l".
And any of the rd.iscsi.param is not honored. Can you please check.
Comment 4 Nilesh Javali (Marvell) 2019-09-09 17:41:13 UTC 
Chris,
In cases of link down on one port, does the script check for the link state before triggering login attempts and can that be controlled.

RHEL 8.2 logs

Hi Chris,

We are facing similar issue on RHEL 8.2 iSCSI boot from SAN multipath with one port down setup. It looks like Dracut login retries is adding significant delay in boot process when one port is down.

When the one is down and system rebooted dracut retries for the iSCSI login 12 times. Which takes approximately 22 min starting from Apr 23 11:17:48 to 11:39:04. Which is a significant portion of the boot process. Refer below log snippet for duration.

=================

Is there a way to reduce Dracut retires using cmdline parameter ?
