Steps for installing the megasr RHEL 7 kmod (RPM) Package

1) Install the megasr-kmod rpm using the following command:

./install_rpm.sh <ahci|isci|ahci_g>

  If megasr rpm is to be installed to claim SCU controller, run  "install_rpm.sh" by typing the following command.
   "install_rpm.sh isci" .
"install_rpm.sh" script is available in the driver package. 
   This will prevent the native/installed isci driver from claiming SCU controller on RHEL 7.

   If megasr rpm is to be installed to claim AHCI controller, run "install_rpm.sh" by typing the following command.
   "install_rpm.sh ahci"
   This will prevent the native achi driver from claiming AHCI controller.

   If megasr rpm is installed to claim the other AHCI controller (configured in RAID mode) on Grantley Server, run "install_rpm.sh" by typing the following command.
   "install_rpm.sh ahci_g"
   This will change the Module load order, so that megasr Driver will be loaded first and claim the AHCI controller which is configured in RAID mode.

 
2) Reboot the system to verify that the driver has been updated.



Steps for upgrading the megasr RHEL 7 kmod (RPM) Package


1) If the OS is installed through RHEL 7 DUD image then to upgrade the megasr Driver, use the following command to upgrade:

	rpm -Uvh kmod-megasr-*.rpm --force

Reboot the system to verify that the driver has been upgraded.

2) If the initial megasr driver is installed through kmod RPM package then also use the following command to upgrade:

	rpm -Uvh kmod-megasr-*.rpm --force

Reboot the system to verify that the driver has been upgraded.
