RHEL 7.x x64
These instructions are relevant for UEFI boot only. Legacy boot is not supported at this
time.
1. Copy the P420m/P320h driver disk image from the support pack software to exter-
nal removable media such as a USB drive.
For example, for a USB drive (/dev/sdb), copy the image to the drive, substituting
your particular string for <kernel_version>:
dd if=mtip32xx-diskimage-<kernel_version>_rhel7.img of=/dev/sdb bs=512
conv=fsync
The <kernel_version> for RHEL 7.0 is 3.10.0-123.el7.x86_64.
2. Boot the RHEL 7.x DVD in UEFI mode with a UEFI-enabled P420m/P320h drive.
3. When the first RHEL screen appears, select Install Red Hat Enterprise Linux 7.0
and press e.
4. Move the cursor to the end of the 'linuxefi' line and add 'inst.dd'; for example:
linuxefi /images/pxeboot/vmlinuz inst.stage2=hd:LABEL=RHEL-7.0\x20Serv-
er.x86_64 quiet inst.dd
5. Press CTRL-x to start the installation.
6. When prompted for the driver package, select the number corresponding to the
USB key containing the driver image and press enter. (Typically, the USB key is
'sda' or 'sdb').
7. The utility searches for the image and displays the list of drivers found in the pack-
age. Only one driver should be listed and it will appear similar to:
DD: Checking device /dev/sda
DD: Processing DD repo /media/DD/rpms/x86_64 on /dev/sda
Page 1 of 1
Select drivers to install
1) [ ] /media/DD/rpms/x86_64/kmod-mtip32xx-3.8.1-1.el7.x86_64.rpm
# to toggle selection, 'n' -next page, 'p' -previous page or 'c' continuous
8. Press c and then enter to install the driver.
9. Press c and enter again to continue.
10. Proceed with the normal installation until just before the final boot into the new
OS.
11. Press CTRL+ALT+F2 to open a new terminal.
12. Type 'chroot' into the newly created system image:# chroot /mnt/sysimage
13. Rebuild the initramfs with the included mtip32xx module using the following
command:# mkinitrd -f --with=mtip32xx /boot/
initramfs-3.10.0-123.el7.x86_64.img 3.10.0-123.el7.x86_64
Note: The above command is for RHEL 7.0 only. If using a newer kernel than the
one that shipped with RHEL 7.0, the command may need to be changed for the
specific kernel version used.
14. Press CTRL+ALT+F7 to return to the GUI screen.
15. Click Reboot. The OS should successfully boot into RHEL 7.x.
