Mirroring VG00

[Rafael Casero]

I'm trying to Mirror vg00, getting the following error:

miaux10: / =>mkboot -a "hpux -lq /stand/vmunix" /dev/dsk/c3t6d0
-a specified but no current boot area on /dev/dsk/c3t6d0

These are the following steps I have taken:

What's missing.

miaux10: / =>pvcreate -B /dev/rdsk/c3t6d0

Shalom,

You have missed a few stps.

Is this 11i v1 ?

pvcreate -B /dev/rdsk/c1t0d0 #use real disk

mkboot -l /dev/rdsk/c1t0d0
mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/c1t0d0 # use real disk


# mkboot -b /usr/sbin/diag/lif/updatediaglif -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?

If you are running 64-bit OS:

# mkboot -b /usr/sbin/diag/lif/updatediaglif2 -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?


vgextend /dev/vg00 /dev/dsk/c1t0d0 # same thing
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c1t0d0

# real disk. repeat for other lvols

lvlnboot -r /dev/vg00/lvol3 # root fs /
lvlnboot -s /dev/vg00/lvol2 #swap

For Itanium, follow this guide:

Hi,
for Itanium mirror procedure follow the attachment ...

Pete,

For some reason I cannot get to this link.

[Torsten.]

Before you begin to follow the steps given in the link provided by Pete, reverse the steps you already done.

Important: vgreduce the disk before you start over.

[Pete Randall]

Sorry - apparently they've moved or removed that link.

Here is another reference. You'll need to find the section titled "Mirroring a Boot Disk with LVM on HP-UX 11i for HP Integrity Servers":

No points for this please, I just want to verify the formatting problem. The link again for copy and paste:

I got Torsten's link to work by clicking on it, then manually editing it to add the ,00.html part that ends up on the third line. You have to sign in to HP passport which redirects you to some other page, but if you then go through the clicking and editing again, it will work.

Hey;

As others have pointed out, the procedures for itanium and parisc are different. I've generated a checklist that I've used quite often - available at:

Here's the same link for itanium servers. Turn to page 630 "Mirroring Root, Boot, and Primary Swap Logical Volumes for HP

HOW TO CREATE A MIRRORED BOOT DISK WITH LVM ON ITANIUM SYSTEMS



This document assumes that MirrorDisk/UX is already installed on the system and patch PHCO_31709 or a superseded patch has been installed afterwards.

To check MirrorDisk/UX is installed use

#swlist â l product B2491BA (servers)
#swlist â l product B5430BA (workstation)

#swlist ¦ grep â i mirror

Check device files with ioscan
#ioscan â funC disk

Use vi to create a partition description file like examples below
#vi /tmp/partitionfile

For HPUX 11.22 uses a 3 line file

2
EFI 100MB
HPUX 100%

For HPUX 11.23 uses a 4 line file

3
EFI 500MB
HPUX 100%
HPSP 400MB

Use idisk to partition the disk as required
#idisk â wf /tmp/partitionfile /dev/rdsk/cxtxdx

Use insf to create device files
#insf â e

Check partitions on disks with
#idisk â p /dev/rdsk/cxtxdx
should display 3 partitions EFI, HPUX, HPSP

Create a physical volume on the desired disk with pvcreate ensuring you specify s2 device files
#pvcreate â B /dev/rdsk/cxtxdxs2

(-f option only required if disk previously used in system)

Add the physical volume to the ROOT volume group using s2
#vgextend /dev/vg00 /dev/dsk/cxtxdxs2

If disk has been previously used initialize efi fat partition
#efi_fsinit â d /dev/rdsk/cxtxdxs1

Use mkboot to place boot utils in boot area on disk and lif files under /usr/lib/efi and /usr/lib/uxbootlif
#mkboot â e â l /dev/rdsk/cxtxdx

use pvdisplay to note the sequence of lvols
#pvdisplay â v /dev/dsk/cxtxdxs2 ¦ more

Create mirror copies of all lvols to be mirrored
#lvextend â m 1 /dev/vg00/lvol1 /dev/dsk/cxtxdxs2
#lvextend â m 1 /dev/vg00/lvol2 /dev/dsk/cxtxdxs2
for all lvols or use this shell loop to extend automatically

#for lvol in lvol1 lvol2 lvol3 ⠦⠦⠦.lvol8 (specify all lvols to be mirrored)
>do
>lvextend â m 1 /dev/vg00/$lvol /dev/dsk/cxtxdxs2
>done

Confirm efi partition is present and populated
#efi_ls â d /dev/rdsk/cxtxdxs1
#efi_ls â d /dev/rdsk/cxtxdxs1 â u /EFI/HPUX/AUTO /tmp/AUTO; cat /tmp/AUTO

Edit the AUTO file to â lq
#efi_cp â d /dev/rdsk/cxtxdxs1 â u /EFI/HPUX/AUTO /tmp/AUTO

#vi /tmp/AUTO
modify boot vmunix to boot vmunix â lq

Then copy file back to both EFI partitions (both disks)
#efi_cp â d /dev/rdsk/cxtxdxs1 /tmp/AUTO /EFI/HPUX/AUTO

Check again
#efi_ls â d /dev/rdsk/cxtxdxs1
#efi_ls â d /dev/rdsk/cxtxdxs1 â u /EFI/HPUX/AUTO /tmp/AUTO; cat /tmp/AUTO

List contents of LIF area on mirrored disk
#lifls â l /dev/rdsk/cxtxdxs2

Update the BDRA and LABEL files
#lvlnboot â R /dev/vg00

Check disks are listed as boot disks for ROOT BOOT and SWAP
#lvlnboot â v /dev/vg00

If any are missing
#lvlnboot â r /dev/vg00/lvol3 /dev/vg00
#lvlnboot â s /dev/vg00/lvol2 /dev/vg00
#lvlnboot â d /dev/vg00/lvol2 /dev/vg00
#lvlnboot â b /dev/vg00/lvol1 /dev/vg00

Add a line to /stand/bootconf for new bootdisk using vi
#vi /stand/bootconf
l /dev/dsk/c0t6d0
l /dev/dsk/cxtxdx

check new disk appears in /etc/lvmtab
#strings /etc/lvmtab

Set alt path for mirrored
#setboot â a [hw path of mirror] disk (11.22 uses std alt path)
#setboot â h [hw path of mirror] disk (11.23 uses HA alternative)
Check PVâ s with
#vgdisplay â v vg00

check all lvols are mirrored with
#lvdisplay â v /dev/vg00/lvol1 ¦ pg
#lvdisplay â v /dev/vg00/lvol2 ¦ pg

Check partitions on disks with
#idisk â p /dev/rdsk/cxtxdx
should display 3 partitions EFI, HPUX, HPSP

Copy contents of HPSP on original disk to mirrored disk partition
#dd if=/dev/rdsk/cxtxdxs3 of=/dev/rdsk/cxtxdxs3 bs=1024k

Note

If cold install of 11.23 - HPSP will not be populated with diagnostics
These need installing from offline diagnostics cd

Reboot server and boot offline diagnostics cd
Select option to run cd installer to install/update contents to HPSP

Once installed on one disk this can be copied with dd as above

shutdown and reboot to alt path to check mirror is bootable

I'm currently going through the process.

According to document, when I create the

/tmp/partitionfile for 11.23

EFI 500MB
HPUX 100%
HPSP 400MB

Not sure how this file should look. And what fields to modify..

First time doing this... as you all can tell.

[Enrico P.]

Hi,
Default is

EFI 500MB
HPUX 100%
HPSP 400MB

This file is for partition your boot disk in three parts.
With ioscan command you will see

/dev/rdsk/c3t6d0s1
/dev/rdsk/c3t6d0s2
/dev/rdsk/c3t6d0s3

you can check this value

diskinfo /dev/rdsk/c3t6d0s1 (EFI size)
diskinfo /dev/rdsk/c3t6d0s3 (HPSP size)
diskinfo /dev/rdsk/c3t6d0s2 (HPUX size)


Enrico

[Rafael Casero]

Not sure what
# - what is this referencing.
HPSP 400MB - Not sure what this is.

[Torsten.]

HPSP - HP service partition, used for the offline diagnostics.

Let me include the /tmp/partitionfile created.

miaux10: / =>cat /tmp/partitionfile
2
EFI 70007MB
HPUX 100%
HPSP 400MB

Thanks, All for your help.

[Torsten.]

Not "2", use "3" if you have 3 more lines in this files. This is the number of partitions.

[Torsten.]

500MB is really enogh for the first (EFI) partition.

Your first line should look like
EFI 500MB

the whole file:

3
EFI 500MB
HPUX 100%
HPSP 400MB

[Rafael Casero]

Can I just rerun the process again, or what do I have to do to revert back ?
