Hi folks,
My first posting here.
I am trying to make a custom init ramdisk on RHEL5.2 with qla2xxx drivers
but the boot ups consistently fail with the following message:
Red Hat nash version 5.1.19.6 starting
Reading all physical volumes. This may take a while...
No volume groups found
Volume group "Volgroup00" not found
Unable to access resume device (/dev/VolGroup00/root)
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
kernel panic - not syncing : Attempted to kill init!
Booting the server with standard 2.6.18-92.1.18.el5 initrd directly from SAN
disk works without any issues. We are trying to use the customized initrd so
that we can make use of the extra features QLogic drivers provide at
hardware level (configured through SanSurfer) instead of using dynamic
multipathing etc.
Following is a rather long mail I submitted at the QLogic forum:
================= START ==========================
OS platform : RHEL5.2 x86_64 & CentOS 5.2
Server HW : IBM BladeServer HS21XM
HBA : QMI2472
SAN : IBM DS4700
(NOTE : Tried the same on both RHEL5.2 and CentOS5.2)
A bit of history:
1. The server can boot up directly from SAN with the current default
"2.6.18-92.1.18.el5" RHEL5.2 kernel.
2. We also have a number of same type HW custom re-compiled with QLogic
qla2xxx drivers on RHEL4.
3. We are trying to use the customized kernel so that we can make use of
the extra features QLogic drivers provide at hardware level (configure
through SanSurfer) instead of using dynamic multipathing etc.
Following is the exact steps I took.
1. Install kernel-devel and kernel-headers packages.
2. download the QLogic driver file and extract the file into /tmp/qlogic
directory
3. issue the command ./drvsetup (which creates the directory
qla2xxx-8.01.07.15
4. ran the following commands:
a) cd qla2xxx-8.01.07.15/
b) grep -r pci_module_init *
and edited the files ql2300.c, ql2100.c, ql2322.c, ql2200.c and
ql2400.c
changing the entry "pci_module_init" to "pci_register_driver" in each
file.
c) ./extras/build.sh install
d) depmod -av
e) mkdir /initrd
5. copied the currently booted kernel image from /boot dir to temp
directory.
cp /boot/initrd-2.6.18-92.1.18.el5.img /tmp/image
6. cd /tmp/image
7. mv initrd-2.6.18-92.1.18.el5.img initrd-2.6.18-92.1.18.el5.img.gz
8. gzip -d initrd-2.6.18-92.1.18.el5.img.gz
(This will be inflated into initrd-2.6.18-92.el5.img file)
9. cd /tmp/image && cpio -i --make-directories < initrd-2.6.18-92.el5.img
10. mv initrd-2.6.18-92.el5.img ../
11. vi "init" file and add:
a) echo "Loading intermodule.ko module"
insmod /lib/intermodule.ko
== just above the line ' echo "Loading qla2xxx.ko module" '
b) echo "Loading qla2xxx_conf.ko module"
insmod /lib/qla2xxx_conf.ko
== just below the line ' echo "Loading qla2xxx.ko module" '
12. cp qla2xxx.ko file from /lib/modules/`uname
-r`/kernel/drivers/scsi/qla2xxx to /tmp/image/lib dir.
13. cp qla2xxx_conf.ko file from /lib/modules/`uname
-r`/kernel/drivers/scsi/qla2xxx to /tmp/image/lib dir.
14. cp /lib/modules/`uname -r`/kernel/kernel/intermodule.ko /tmp/image/lib
15. made the new initial ramdisk image:
cd /tmp/image && find . | cpio -o -H newc | gzip -9 -n >
../initrd-`uname -r`-QLFO.img
16. cd .. && cp initrd-`uname -r`-QLFO.img /boot
17. vi /boot/grub/menu.lst file and added the QLogic initrd entry
18. # init 6 from console
Following is the error I'm still getting.
----------------------------------------------------------------

following 2 lines)**

Since I don't see any other error messages, I think I can safely assume all
kernel modules loaded properly but am still having grief with the LVs. This
is the major difference between RHEL4 and RHEL5. We didn't have LVs in our
RHEL4 servers. Then again, why is it working with the default RHEL5.2
kernel? It finds the LVs without any problems. Am I looking into something
totally unrelated with QLogic modules now?
==================== END ==========================
I've been trying to resolve this problem for the past week without success.
Help is much appreciated. TIA.
