+++ This bug was initially created as a clone of Bug #1657672 +++
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
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: iscsistart: version 220.127.116.114-10
[ 82.535366] dracut-initqueue: iscsistart: initiator reported error (15 - session exists)
[ 82.540439] dracut-initqueue: iscsistart: initiator reported error (15 - session exists)
[ 82.545569] dracut-initqueue: Warning: 'iscsistart -b ' failed with return code 0
4. This adds delay in booting of OS.
The OS boot takes more than 5 mins to boot.
The OS should boot within less than 5 mins.
Adding OS boot logs showing multiple login attempts.

Below are the multipath.conf settings,
I'm a little confused as to why you opened this bug against 7.5 after already having one opened against 7.6 - 1657672. The last opportunity to get a zstream fix for 7.5 for this bug would have been on 2018-08-07. I am closing this one as a 'wontfix.' Please email me directly if you have any questions.
Just to highlight that issue exists with 7.5 as well, created clone of 7.6 - 1657672.
Well this issue is still seen with newer distros like RHEL 8.1 too.
