I have been using a modified version of 4.1.99.svn4556_bli-1 to load my
i386 rhel6.x servers as
described below. I am now looking at imaging similar machines but now with
the x86_64 version
of rhel6.3 so I need like initrd_template( and boot_standard if it works)
packages.
What versions should I be trying ?

Loading RHEL 6.2 using 4.1.99.svn4556_bli-1
Using systemimager 4.1.99.svn4556_bli-1(ext4 enabled version) I have
successfully imaged a
RHEL 6.2 image to HP DL380G7 hardware(p410 array controllers). I was
considering using SALI
however for RHEL6.x grub2 is not an issue and ext4 support is included in
4.1.99.svn4556_bli-1.
The setup I was imaging is a Proliant DL380G7 server with two p410
controllers(p401i and p410)
with raid1 for root/boot/swap on the p410i and raid5 for /data on the
p410. The system is running
the latest RHEL 6.2.
The attempted to image the system in two ways:
1. standard kernel
2. uyok
1. standard kernel
I eventually got this to work but only after major modifications to
the install script and manually
setting up grub. The major issue here is that the default kernel uses
the cciss driver and
device naming(ex /dev/cciss/c0d0p2) and the RHEL6.x uses the hpsa
driver(scsi naming ex /dev/sda).
See
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c02677069/c02677069.pdf
.
In general RHEL 5.x and before uses the cciss driver and RHEL6.x uses
the hpsa when possible.
I presume the standard kernel could be built with the hpsa module and
some version logic
applied to resolve this.
2. uyok
This worked successfully after making some changes to address :
- Needed modules(ie hpsa) as symbolic links under
/lib/modules/(uname -r)
ex
[root@scdev ~]# ls -al
/lib/modules/2.6.32-220.4.2.el6.i686/weak-updates/hpsa/hpsa.ko
0 lrwxrwxrwx 1 root root 50 Mar 5 04:05
/lib/modules/2.6.32-220.4.2.el6.i686/weak-updates/hpsa/hpsa.ko ->
/lib/modules/2.6.32-71.el6.i686/extra/hpsa/hpsa.ko
[root@scdev ~]#
This results in the modules not being copied correctly in the
generated initrd.
I resolved this by modifying the UseYourOwnKernel.pm rsync
invocations
to copy the resultant files(the L rather then the l option. I
include the diff
below.
- Numerous /lib/firmware files were missing in the initrd. By default
the
bnx2 nic driver(driver for the four nic's on the motherboard) as
well as
others in the RHEL6.2 kernel request firmware which is missing in
the
uyok initrd. I got this to work by :
- modifying UseYourOwnKernel.pm to copy /lib/firmware to the
initrd.
Unfortunately this copies all of firmware as I couldn't figure
out how to
dynamically copy what was needed.
- modified rcS under the std template to start udev BEFORE the
modules
are inserted.
- rcS : start udev before loading modules.
- under the std template :
/usr/share/systemimager/boot/i386/standard/initrd_template/etc/init.d/rcS
- The ramdisk_size must be set high enough to accept the larger
initrd.
- I had to si_cpimage as part of testing and noted that for yuok the
kernel and initrd.img files are not copied. They had to be copied
manually.
Notes :
When creating the image initially I also had to change si_prepareclient
to use parted rather then sfdisk. I believe a bug
was submitted on this a long time ago which was never applied. parted
supports gpt
partitions and sfdisk does not.
