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:
RHEL 8.2 System takes 45 min to boot on 4 port adaptor with NPAR EP mode.
Four ports are configured with iSCSI boot from SAN with same target.
All the port logged in to the target successfully.

It has been observed that swap partition timesout and its dependency also fails. After which dracut take long time to boot or go to next step.

Version-Release number of selected component (if applicable):
Linux R7415-RH82-iSCSI 4.18.0-193.el8.x86_64 #1 SMP Fri Mar 27 14:35:58 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
How reproducible:
Configured four port for iSCSI boot from SAN configuration in NPAR EP mode i.e. fours port with 16 function out of which 4 are iSCSI functions.
Steps to Reproduce:
1. Configured iscsi four port for iSCSI BFS
2. INstall RHEL 82 OS
3. First boot
Actual results:
Takes long time to boot
Expected results:
Less time expected.

=> I think this is caused by HW malfunction.

Please suggest why this is HW malfunction.
The test scenario here is Boot from SAN and the swap partition which timesout is on the same remote LUN as the root partition.
