LVM boot disk from scratch

borut kurnik_1 — Wed, 26 Sep 2007 08:24:25 GMT

Hi!

I've got rx1600 with two 36GB disks
dual channel Ultra320 SCSI controller.

c2t0d0 is VxVM managed current boot disk and
I'm trying to configure c2t1d0 as second boot
disk with LVM.

Everything seem to be ok, but when I try to
boot, loader starts but doesn't find the kernel. Looks that it cannot recognize
the LVM disk layout...

Would anybody be so kind and take a look
at my procedure and maybe give me a hint
what I'm missing...

Thanks,

Borut

Procedure:

[root@gremlin bin]# bash -x mklvmbd.sh c2t1d0
++ basename mklvmbd.sh
+ SYNTAX='mklvmbd.sh '
+ '[' 1 -ne 1 ']'
++ basename c2t1d0
+ RDEV=/dev/rdsk/c2t1d0
++ basename c2t1d0
+ CDEV=/dev/dsk/c2t1d0
++ basename mklvmbd.sh
+ IDF=/tmp/mklvmbd.sh_idisk.inp
+ cat
+ idisk -w -f /tmp/mklvmbd.sh_idisk.inp /dev/rdsk/c2t1d0

I think you should create de lvols in the correct way (lvol1, lvol2 and lvol3) and use the following commands:

# lvlnboot -r /dev/vg00/lvol3 /dev/vg00
# lvlnboot -b /dev/vg00/lvol1 /dev/vg00
# lvlnboot -s /dev/vg00/lvol2 /dev/vg00
# lvlnboot -d /dev/vg00/lvol2 /dev/vg00

Re: LVM boot disk from scratch

J. Bravo — Wed, 26 Sep 2007 08:59:41 GMT

The equivalent commands for itanium architecture for lifls/lifcp are:

# efi_ls -d /dev/rdsk/c2t1d0s1

edit the AUTO file so we can boot when one disk is missing:

# efi_cp -d /dev/rdsk/c2t0d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO

# vi /tmp/AUTO

modify "boot vmunix" to "boot vmunix -lq"

then put back the file on both EFI partitions with:

# efi_cp -d /dev/rdsk/c2t1d0s1 /tmp/AUTO /EFI/HPUX/AUTO

# efi_cp -d /dev/rdsk/c2t0d0s1 /tmp/AUTO /EFI/HPUX/

Hi again.

Thanks four you quick replies.

J.Bravo,

lvol3 is definitely swap & lvol2 is
root volume, as I explicitely specified that
with '-n' qualivier.

AUTO seems to be ok, loader just cannot
find the kernel (vmunix), but I don't
think this is a problem here.

Aussan,

I'll dig into that document right away.

Thanks again,

Borut

Hi, itÂ´s possible that if you have a 11.23 system, you need three partitions in the file for use with idisk command:

# vi /tmp/partitionfile
3
EFI 500MB
HPUX 100%
HPSP 400MB

Regards.

Re: LVM boot disk from scratch

J. Bravo — Wed, 26 Sep 2007 09:58:47 GMT

Do you have updated the /etc/fstab file on your LVM boot disk to reflect the new lvols?

Regards.

Re: LVM boot disk from scratch

Torsten. — Wed, 26 Sep 2007 10:19:45 GMT

I never "cloned" a vxvm disk to lvm this way, but

- use the default order
lvol1 /stand
lvol2 swap
lvol3 /

Some commands are missing, like
efi_fsinit -d /dev/rdsk/...
...
echo "l /dev/dsk/..." >> /stand/bootconf
...
lvlnboot -r /dev/vg00/lvol3
lvlnboot -b /dev/vg00/lvol1
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2

From EFI, go to the disk and start hpux loader - interrupt the autoboot.

Run "hpux ls" or ll - what can you see?

Hi!

Yes, tried everything (3 partitions & had fstab on target disk updated from the begining, updated /stand/bootconfig, ...), but loader just doesn't recognize the new boot disk.

HPUX>boot
Could not open file vmunix to check for directory
Could not open vmunix

Kernel loading failed

HPUX>ls
Could not open dir:

Good morning:

Try to format the first partition to FAT after the creation of the 3 partitons (idisk) with:

efi_fsinit -d /dev/rdsk/c2t1d0s1

and then repeat the rest of your procedure.

Hope it helps.

Regards.

Hi!

Although 'mkboot -e -l ...' is suppose to
do that ('efi_ls' shows EFI fs after it
just fine), I tried that too, same story.

Thanks anyways,

Borut

Re: LVM boot disk from scratch

J. Bravo — Thu, 27 Sep 2007 04:32:26 GMT

Hello!

Could you attach the output of the following commands, please?

efi_ls -d /dev/rdsk/c2t1d0s1 /EFI/
efi_ls -d /dev/rdsk/c2t1d0s1 /EFI/HPUX
lvlnboot -v

Regards;

Hi!

Thanks for your help, J.Bravo.

I will but in a few hours time (don't know
exactly) as I'm out of firm today.

However it will be /dev/rdsk/c2t0d0s1 as I
temporarily gave up and installed
LVM managed boot disk from inst. CD to
/dev/rdsk/c2t1d0s1 .

I've already prepared a script,
so it will only take me a few minutes to
get to the problematic part and send
you efi_ls output imediately.

Regards,

Borut

Hello!

/dev/[r]dsk/c2t1d0 is now my LVM boot
device (DVD installed, boots ok) and
I used the same procedure to create
bootable LVM layout on /dev/[r]dsk/c2t0d0.

Result is the same, of course :-/
