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.

upsteam patch screen

Description of problem:

Cu has installed RHEL 6 and RHEL 7 systems. Now cu connected SIM0 and SIM1 on system via miniSAS HD cable.

When RHEL 6 boots with SIM0 and SIM1, it doesn't boot into OS and gets black screen.  But for the RHEL7 , the error had no found .

From the source code checking in the 0.97 grub  version, I found that  for the 

disk support limits , it is 128.

But in the upsteam ,  there is the patch for fix the disk limits so that  it can recongize  the disk more than 128. 

For the CU questions,  for the patch,  does Red Hat provide it too?  If not ,  How can fix it ?  



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


How reproducible:


Steps to Reproduce:

1.Install RHEL 6.5x64 UEFI via PXE server.
2.Connect SIM0 and SIM1 to 9300-8e via miniSAS HD cable.
3.Power on system, boot into BIOS setting FRB2->do nothing.
4.Save setting and reboot.
5. System can’t boot into RHEL6.5x64 UEFI with black screen while SIM0/SIM1 both are connect to the same 9300-8e.
6.If only connect one of SIM0 or SIM1, CentOS can boot into normal.
7.RHEL6.7 also have this issue, RHEL7.0 doesn't find this issue.

Actual results:

The system can't boot in the RHEL6.x version 

Expected results:

OS should be boot normal while SIM0/SIM1 both are connect to 9300-8e.

Additional info:

Reproducible: Yes, 100%
If only install 63 pcs SAS SSD with dual path.This issue was not occur.
If only install 64 pcs SAS SSD with dual path.This issue was occur.
So the HDD limit was 63 pcs with dual path or over 126pcs HDD with single path.

Hello Wei,

I don't see any commit from <holcapek> in the official grub2/grub-legacy repository. Please, provide us with a link to the git repository/commit itself.

Wihout it I can't tell if this patch has been already applied in the latest grub package, and I don't have that specific hardware available to test it by myself.

Thank you,

Dee'Kej

When Red Hat shipped 6.8 on May 10, 2016 Red Hat Enterprise Linux 6 entered Production Phase 2. https://access.redhat.com/support/policy/updates/errata#Production_2_Phase
That means only "Critical and Important Security errata advisories (RHSAs) and Urgent Priority Bug Fix errata advisories (RHBAs) may be released"
That also means no new RFEs.  The customer case requesting this issue has also been closed for some time, so this BZ is being closed WONTFIX. Please re-open this feature request if it is critical for the customer and provide a thorough business justification.
