[sisuite-users] Which version ?

[<dav...@cn...>]

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.
