[rhn-users] aacraid driver

[Doerbeck, Christoph]

You need update 5 as a minimum, and then after the OS is installed ...
you need to upgrade the raid driver with the one from IBM latest
ServeRaid CD.  Otherwise you box will be extremely unstable :-)

	I have been attempting to install an IBM x366 with Redhat AS3
Update 4 (x86_64)  with little to no luck.  The Broadcom card is not
recognized, nor the is Adapatec SAS raid card (BIOS v5.0.0)/IBM
ServerRAID 8i controller.  I was finally able to get it to install by
using the install images of Update 4.1 (which recognizes both the RAID
controller and network card) over pxe/http, and rebuilding the installer
hdlist files to point to a AS3 update 4 distro.  The logical step to
take would be to use the working AS4 update 1 installation.  However,
Oracle has not certified AS 4 and will only provide support for AS3 at
this time.  AS3 update 5 also does not recognize the broadcom or
Adapatec raid controller.

	Using the AS4.1 boot/install, partitioning the disks with the
gui utility and installing packages, the machine boots and the aacraid
driver fails.  The host panics because it cannot find a root partition:

	Loading sd_mod.o module 
	 attempt to access beyond end of device 
	 01:00: rw=0, want=7235939, limit 8192 
	 01:00: rw=0, want 7235939, limit 8192 
	Loading aacraid.o module 
	RedHat/Adaptec aacraid driver (1.1.5[2386]) 
	  /lib/aacraid.o: init_module: No such device 
	Hint: insmod errors can be caused by incorrect module
parameters, including invalid IO and IRQ parameters 
	Error: /bin/insmod exited abnormally 
	Loading jdb.o module 
	Loading ext3.o module 
	VFS: cannot open root device "VolGrp00/LogVol00" or 00:00 
	Please append a correct "root= " boot option 
	Kernel panic 

	Booting from the AS 4.1 rescue CD I am able to chroot to the
/mnt/sysimage and play with the distro.  I ran the up2date utility and
downloaded the most recent kernel and package upgrades with the same
results.  The IBM support CD contains "updated" aacraid and broadcom
drivers.  The broadcom bcm5700  drivers install correctly, but the
aacraid drivers fail with the above results.

	Has anyone had a similar experience
