Unable to Install ISO Package Using CentOS Linux Release 7.5.1804 on HP Gen 11

[rlam1298]

Unable to install ISO package on HP Proliant DL360 Gen 11 with ISO package containing CentOS Linux Release 7.5.1804 and Real time Linux Kernel version of 3.10.0-862.11.6.rt56.819.el7.x86_64. The error displayed indicates that the RAID 1 Configured Logical Drive with 2 Physical drives is not detected.

The same ISO package installed successfully on HP Proliant DL360 Gen10.

Back to HP Gen 11, when I changed the ISO package build to use CentOS Linux release 7.9.2009, the RAID drive is detected and the ISO installation completes on HP Proliant DL360 Gen 11.

Since my team and I have performed a lot of testing of the ISO package containing CentOS 7.5.1804 with kernel 3.10.0-862.11.6.rt56.819.el7.x86_64, how can I make the ISO package installation work using CentOS 7.5.1804 with kernel 3.10.0-862.11.6.rt56.819.el7.x86_64 on the Gen 11 so that the RAID drive can be detected?

What's your RAID cards?

What's your RAID cards?

In other words, what does lspci -nn tell about the cards?


CentOS 7.5 has been unsupported since December 2018 (when 7.6 was released).
If you have used only the 7.5's install image and never installed available updates, then your systems date to May 2018.
By now several critical vulnerabilities of 7.5 (as it was Dec 2018) are known and will never get fixes.
Since systems that have 7.5 definitely should not be on network, nor have any support, their use seems extremely limited.

Even the CentOS 7.9 dies next June. If your "testing" takes 5+ years, then you should start with something that is not completely dead in couple months.

Overall, a basic premise of RHEL is that a major version does not really change over its lifetime. The point updates add only security and bug fixes, and some new features (such as drivers for newer hardware).

For the Gen11 server, the RAID bus controller is
[root@HOST ~]# lspci -knn | grep 'RAID bus controller'
3a:00.0 RAID bus controller [0104]: Broadcom / LSI MegaRAID 12GSAS/PCIe Secure SAS39xx [1000:10e2]

I forgot to mention that an update to 2018-11-20 has been done to the CentOS Linux Release 7.5.1804.

It doesn't really matter. CentOS 7.5 has been unsupported since the release of 7.6 on 2018-12-03. At that point, support for 7.5 stops and you are expected to yum update to 7.6. You should not be using something that is missing over *5 years* of security updates. None of what you are running now is supported and it has not been supported for 5 years.

Update.
