Fixes & Enhancements
Fixes - N/A
Enhancements - Updated release of Linux RHEL 4.0 MegaRAID 32-bit Driver.
Dell Technologies recommends applying this update during your next scheduled update cycle. The update contains changes to maintain overall system health. It ensures that the system software remains current and compatible with other system modules (firmware, BIOS, drivers, and software) and may include other new features.
1. This driver update package only contains support for x86 based processors. 2. A warning message is encountered when a logical disk is configured without a partition. After Linux OS installation or any action that causes system devices to be scanned, the user will see the following warning message right after the login screen: "megaraid: invalid partition on this disk on channel 0" This message will disappear once a partition is created on all logical drives or if the logical drive without a partition is deleted. 3. A warning message is seen if errata kernel RPMs are installed after installing the megaraid driver. The following message is printed: "No module megaraid found for kernel x.y.z-p" This message is seen because the /etc/modprobe.conf file specifies that the megaraid driver is to be added to the initial RAM disk (initrd), but the driver is not yet built and installed for the kernel by DKMS. To boot from this kernel, the megaraid driver should be built and installed for thekernel as described in Section 2.2.5 of the Driver Release Notes and then adding the line: initrd /initrd-x.y.z-p.img to /etc/grub.conf in the stanza for the kernel version installed. 4. During the fresh Linux installation, the operating system cannot determine drive/device order information based on system BIOS settings. This may lead to undesired drive/device orderings during the install. It is recommended to perform the install with only the target hard drives and storage controller present that the user intends to install to, then later add the additional storage controllers and hard drives to the system once the installation is complete.
Updating the Driver Using RPM After OS is Installed
This procedure installs the megaraid and DKMS RPM packages contained in this Dell driver release.
1. Create the driver disk by following the steps in Section 2.1.
2. Type the following commands under a Linux command shell:
mount /dev/fd0 /media/floppy cd /media/floppy source install.sh
NOTE: The floppy drive in the system may not be enumerated as fd0. For example, a USB floppy drive may have a device name of /dev/sda. Determine the device name for the floppy drive and substitute fd0 with the proper device name in the command above.
3. Reboot the system for the changes to take effect.
NOTE: The megaraid module is only installed for the kernel currently running.
