Important Information
- This driver update package only contains support for x86 based processors.
- 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, you 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.
- A warning message is seen if errata kernel RPMs are installed after installing the megaraid2 driver. The following message is printed:
"No module megaraid2 found for kernel x.y.z-p"
This message is seen because the /etc/modules.conf file specifies that the megaraid2 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 megaraid2 driver should be built and installed for the kernel as described in section 2.2.3 and then adding the line:
initrd /initrd-x.y.z-p.img
to /etc/grub.conf in the stanza for the kernel version installed.
- After performing a fresh Linux installation using the driver update, the /etc/modules.conf file may contain unused entries specific to the native 'megaraid' driver that has been replaced by this 'megaraid2' driver update package.
'alias scsi_hostadapter1 megaraid'
These entries are created during the operating system installation and may generate error messages during the OS boot process by attempting to load the 'megaraid' driver after 'megaraid2' has already been loaded. To avoid these messages, it is recommended to delete the unused 'megaraid' entries from the etc/modules.conf.
- 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 you intend to install to, then later add the additional storage controllers and hard drives to the system once the installation is complete.
For an existing RHEL 2.1 installation, the addition of another storage controller may change the boot device ordering and impact the operating systems ability to find the root file system partition. To ensure that the operating system can still properly find the partition, it is recommended that before adding the additional controller to edit the /etc/grub.conf and /etc/fstab to use file system labels instead of the hard-coded device names.
(Ex. root=LABEL=/ instead of root=/dev/sda2)
This change is not necessary in RHEL 3.0 or later since those installers already utilizes file system labels during installation.
- After performing a fresh Linux installation using the driver update disk, it is important to update the driver using the rpm after the first boot (See section 2.2.2 of release notes for more instructions). During a fresh Linux installation, the Linux operating system places drivers from the update disks in a separate location than the usual location drivers are stored. This may generate error messages during the OS boot process by attempting to load the driver a second time after the driver has already been loaded. It may also prevent the mkinitrd command from completing, indicated by the message "megaraid2.o: binary operator expected." Updating the driver with the rpm stores the driver file in the proper location.
