Before you beginīefore you install this driver on an embedded controller, you must configure a RAID drive group on the embedded controller that controls the drives where you will install the OS (pSATA and/or sSATA). Note: If you use an embedded RAID controller with Linux, both the pSATA and the sSATA controller must be set to LSI SW RAID mode. This topic describes the fresh installation of the RHEL device driver on systems that have the embedded MegaRAID stack. Procedureįor the specific supported OS versions, see the Hardware and Software Compatibility Matrix for your server release. to resolve this please follow the steps at the bottom of this document to preserve the disk nomenclature for M.2 install. this can cause confusion due to how linux modules are loaded on installer. please note, upon installation wizard initialization the disk may show up as a separate disk / partition then what is wanted for install. RHEL still detects the dd.img as dd.iso it is only the Cisco IMC virtual drive mapper that sees it as an img file. This allows you to map the RHEL installation ISO as a virtual CD/DVD and the renamed dd.img driver file as a virtual floppy disk or virtual removable disk at the same time. Workaround: This procedure simplified the steps by renaming the dd.iso driver file to dd. iso file at a time, and only as a virtual CD/DVD. The Cisco IMC virtual drive mapper can map only one. further complicating things, In RHEL 7.1 and later, the file type of the dud.img driver image was changed to dd.iso. Issue: Previously, in Red Hat 6.10 and below, the way to install was to map the Server installer ISO and then do a whole bunch of extra steps to get the drivers and os installed. This document will help resolve the issue of the correct modules, and drives being loaded for redhat operating Systems. When trying to install on later series M4 or M5 rack mount servers, the OS has trouble with the embedded raid controller and installing to the correct drives.
