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:
When installing RHEL6-snapshot10, at the time when you select a disk for installation, when I select a multipath device, I get the message, "no usable disks have been found".  This is an HP blade system, connected through an Emulex Mezz card (I've tried both LP1105 and a converged network adapter).  I've tried it through a Brocade and a QLogic fabric.  I've also changed storage arrays.  I've tried an EVA6400 and an XP20000.  I've also tried both i386 and x64 flavors of RHEL6.  I've also tried doing a dd of dev/zero to the boot LUN I'm trying to use.  All of these produce the same results.  However, if there's only one path, there is no problem.

Version-Release number of selected component (if applicable):
I'm not sure what the release version numbers are with Snapshot-10

How reproducible:
For me, this happens every time.

Steps to Reproduce:
1. begin install of RHEL6 Snapshot10
2. choose a multipath device to install the OS to.
3.
  
Actual results:
Message "No usable disks have been found"

Expected results:
I expected the disk to be able to be used for installing the OS.

In this log, I'm noticing some lines where it's ignoring ALL of the multipathed devices.

This issue has been proposed when we are only considering blocker

I do not have access to that bug report.  Can you grant it?  Or give me status on the issue?

Thanks!

A potential fix for this issue is in anaconda-13.21.74-1 and is currently being tested.  If all goes well, it'll be fixed in RHEL6 GA,
