1. Perform the following operations to install driver media:
   • PERC Linux driver ISO:
     1. Download the PERC Linux driver package from the Dell Support site.
     2. Extract two base directories from the tar.gz package (tar.gz > tar > base directories).
     3. Extract the ISO file that is available in the zipped disks-x directory. For example, RHEL79/disks-1/megaraid_sas-07.719.03.00_el7.9-1.x86_64.iso.gz > megaraid_sas-07.719.03.00_el7.9-1.x86_64.iso
     4. Mount the ISO to the Server, burn the ISO to a CD or DVD or copy the ISO file to a USB. The USB has to match with the ISO.
