Created attachment 1132159 [details] 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@gmail.com> 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
