Hello!
I have installed Oracle Linux 7.9 on the server what connected to datastorage with QLogic HBA. That is a fresh installation on brand new hardware. And I have a problem just from the start. My problem is that Oracle Linux 7.9 can't detect and show up disks/luns from datastorage attached to QLogic HBA. A connectivity between QLogic HBA and datastorage is established and I can see QLogic HBA WWN in datastorage control panel, but disks/luns are not shown in operating system.
I have also tried to install Microsoft Windows Server 2016 on that hardware. The result is fine - everything is working, luns are detectable and accessible. So it's not hardware problem.
Trying to resolve a problems I was searching such symptoms on Internet forums but was not been succeeded in finding anything for Oracle Linux 7.9.
But I found same symptoms for Red Hat Linux versions greater then 7.4 installed on the hardware with QLogic HBA.

In these posts people were not able to detect their luns after upgrade to RHEL 7.5 or 7.6. I am not the customer of Red Hat, so I can't access to the solution provided by Red Hat.
But I very do believe that a root of the cause is the same for Oracle Linux 7.9 as for RHEL.
So I need a help, because I don't know how to overcome this.
Hope your help.
