12 Jul 11 Migrate VXVM booted system to LVM
From the HP-UX Veritas Administration guide, buried on page 106
This example shows how to create an LVM root disk on physical disk c0t1d0
after removing the existing LVM root disk configuration from that disk.
BOOTBG=$(vxdg bootdg)
vxprint -htg $BOOTDG | grep ^dm
dm rootdisk01 disk233_p2 auto 1024 142450592 –
dm rootmirr disk234_p2 auto 1024 142450592 –
# You get the boot disk from this command. Break off the s2 if you are using legacy devices you can use them or the agile SDF devices.
# You may need to use vxbrk_mirror to break the mirror. Make sure you know which disk you are booted from. Check syslog to be sure. setboot is not a good indicator.
# Due to a wordpress error I’ve been forced to take the path etc vx bin out of the commands. I will fix this when wordpress stops blowing chunks on this data. Where there are spaces there need to be slashes.
# etc vx bin vxdestroy_lvmroot -v c0t1d0
# etc vx bin vxres_lvmroot -v -b c0t1d0
The -b option to vxres_lvmroot sets c0t1d0 as the primary boot device.
As these operations can take some time, the verbose option, -v, is specified to
indicate how far the operation has progressed.
This command takes care of setboot and all details. Then just boot from the console.
This procedure does not remove VxVM software. The daemon still runs. But your system now boots LVM and that makes using Dynamic Root Disk (DRD) much easier.

05 Jul 11 VxVM replace boot disk
Create a partition description file
(Need to update the EFI and HPSP size below according to the other root disk partition’s size)
This examples is where the new disk is disk85. Applies only to HP-UX 11.31 with VxVM as boot drive manager.
# vi /tmp/efipart
3
EFI 500MB
HPUX 100%
HPSP 400MB
Use the idisk(1M) command to partition the disk according to this file
# idisk -wf /tmp/efipart /dev/rdisk/disk85
Write EFI info to the EFI partition on the disk
# mkboot -e -l /dev/rdisk/disk85
Confirm the AUTO file entry is intact It should be “boot vmunix”
# efi_cp -d /dev/rdisk/disk85_p1 -u /EFI/HPUX/AUTO /tmp/efi; cat /tmp/efi
If found any difference, edit /tmp/efi file as below to update the entry “boot vmunix”
#echo “boot vmunix ” > /tmp/efi
Update auto file
#efi_cp -d /dev/rdisk/disk85_p1 /tmp/efi /EFI/HPUX/AUTO
Confirm the AUTO file entry again, It should be “boot vmunix”
# efi_cp -d /dev/rdisk/disk85_p1 -u /EFI/HPUX/AUTO /tmp/efi; cat /tmp/efi
Initialize the disk as VXVM boot disk
#### vxdisksetup -iB disk85_p2 ((lives in etc vx bin slashes removed due to Word Press error))
Add the disk to the existing rootdg
# vxdg -g rootdg adddisk rootdisk02=disk85_p2
Write Volume Manager volume information to the LABEL file:
# /opt/VRTS/bin/vxbootsetup rootdisk02
Display the LIF and Volume Manager label information:
# vxvmboot -v /dev/rdisk/disk85
Check the Mirror status ( Each volume should be with two plex )
$ vxprint –htg rootdg |egrep –i “^v|^pl”

15 Jun 11 Why HP-UX root shell needs to be /sbin/sh
Thanks to Jibn Antony of the Best Buy IDC team for validating.
So who cares what the root shell is? You do if you try to boot your system into single user mode with root shell changed to a shared executable shell, you will find out the hard way. The system won’t boot.

06 Apr 11 setboot hardware path to legacy hardware path. A converter.
HP-UX 11.23
setboot provides output only including the hardware path (ioscan -H).
When calculating DRD clone targets and such you need the regular legacy device path.
Here is a converter, built with a little help from JRF on the ITRC forums.
First get the setboot path. Might want to use the full path of the setboot command in practice.
pboot=$(setboot | grep ^Primary | awk ‘{ print $NF }’);
aboot=$(setboot | grep ^Alternate |awk ‘{ print $NF}’);
abootdisk=$(ioscan -kfnCdisk | awk -v aboot=${aboot} ‘/aboot/ $0~aboot {getline;print aboot,$2}’ | awk ‘{ print $2 }’);
pbootdisk=$(ioscan -kfnCdisk | awk -v aboot=${pboot} ‘/pboot/ $0~pboot {getline;print pboot,$2}’ | awk ‘{ print $2 }’);
The slick part is getting the variable in and out of awk.
Uses ioscan.

16 Mar 11 Preparation procedure for hpux boot disk (11.31)
# vi /tmp/idf
3
EFI 500MB
HPUX 100%
HPSP 400MB
Use the idisk command to initialize:
idisk -wf /tmp/idf /dev/rdsk/disk8
Replace disk with the disk you intend to use.
insf -e -C disk
# May need to be used in advance to insure the device is recognized.

01 Jul 10 Quick and dirty awk trick to see all Fiber Channel status
I needed to update documentation and I needed more information that my prior syslayout.sh script provided on fiber.
# Improvement by JRF on the ITRC forums.
ioscan -kfnC fc | awk ‘/fcd/ {getline;fcd=$NF;print fcd,$2}’ | while read -r fdev
do
fcmsutil ${fdev} | awk ‘/Hardware / {print $5};/World / { print $7}’
done
Ouput looks like this:
0/0/12/1/0/4/0
0x5001438002a24979
0x5001438002a24978
0x204f000dec81b540

0/0/12/1/0/4/1
0x5001438002a2497b
0x5001438002a2497a
0x2093000dec81b480
0x2010000dec81b481
2/0/12/1/0/4/0
0x5001438002a24d35
0x5001438002a24d34
0x2050000dec81b480

0x5001438002a24d37
0x5001438002a24d36
0x2093000dec81b540
0x200f000dec81b541
Second, new improved version (Girsah Chadash)
ioscan -kfnC fc | awk ‘/fcd/ {getline;fcd=$NF;print fcd,$2}’ | while read -r fde
v
do
fcmsutil ${fdev} | awk ‘/Hardware / {print $5};/World / { print $7}’ | awk’ {printf “%s %s %s %s %s”,$1, $2, $3, $4, $5;}’
fcmsutil ${fdev} | awk ‘/Hardware Path/ {PATH=$5};
/N_Port Node/ {NNODE=$7};
/N_Port Port/ {NPORT=$7};
/Switch Port/ {SPORT=$7};
/Switch Node/ {SNODE=$7};
END{print PATH, NNODE, NPORT, SPORT, SNODE}’
done
Next innovation would be to combine the awk statements in the while loop and pull off the output with a single awk command. I may do this, but I might need help from an awk guru.
The ioscan output is multi line, so the real innovation is using the getline function of awk to get the second line of data and ignore the first. The filter /fcd gets rid of the column format information.
Yes it could be done with grep, but it is more AWKFUL this way.
Updated document to provide some indentation. Trying to make the code easier to read. That may force me to add formatted scripts to download, which I will get to as time permits.

09 Jun 10 System I/O layout (EMC specific)
This is a script designed to document the layout of a system. It is EMC specific and requires the output of the inq command, which I store in /tmp/inq.txt
It can however be adapted to non EMC disk systems. It correctly shows the port/lba layout and status of network and fiber I/O the way it appears on the outside of the system. Two tables are included to permit lookups of the port/lba information. It has worked on blades, and is certified for rp8420 and superdome systems.
It has only been tested on HP-UX 11.31.

20 Oct 09 HP-UX Integrity Software mirror procedure
This was written by a former colleague. It is better than anything else I have seen. SEP
Mirroring a Boot Disk with LVM on HP-UX 11i for HP Integrity
Servers
The following diagram shows the disk layout of a boot disk. The disk
contains a Master Boot Record (MBR) and Extensible Firmware
Interface (EFI) partition tables that point to each of the partitions. The
idisk
command is used to create the partitions (see idisk (1M)).
Figure 6-5 Example LVM Disk Layout on HP Integrity Server
Before starting the procedure, make sure that add-on product HP
MirrorDisk/UX (B5403BA) is installed. This product is an extra-cost
product available on the HP-UX 11i application release media. For
example:
swlist -l fileset | grep -i mirror
LVM.LVM-MIRROR-RUN B.11.22 LVM Mirror
Step 1.
file.
Partition the disk using the idisk command and a partition description
a.
Create a partition description file. For example:
vi /tmp/idf
In this example the partition description file contains:
3
EFI 500MB
HPUX 100%
HPSP 400MB
NOTE
an EFI partition, an HP-UX partition, and an HP Service partition.
Boot disks of earlier HP Integrity Servers may have an EFI partition
of only 100MB and may not contain the HPSP partition.
The values in the example represent a boot disk with three partitions:
b.
Partition the disk using idisk and your partition description file:
idisk -f /tmp/idf -w /dev/rdsk/c3t1d0
c.
To verify you can run:
idisk /dev/rdsk/c3t1d0
Step 2.
the partitions. For example:
Use the insf command with the -e option to create the device files for all
insf -e -H 0/18/1/2/0.0.1.0
You should now have eight device files for this disk:
/dev/[r]dsk/c?t?d?
(This refers to the entire disk)
/dev/[r]dsk/c?t?d?s1
(This refers to the EFI partition)

disk:
Use pvcreate to make the HP-UX partition of the disk an LVMmanaged
pvcreate -B /dev/rdsk/c3t1d0s2
Step 4.
Add the disk to vg00:
vgextend vg00 /dev/dsk/c3t1d0s2
Step 5.
Place the boot files on the disk using mkboot:
mkboot -e -l /dev/rdsk/c3t1d0
Step 6.
Copy any autoboot file from the original boot disk to this one.

partition to the current directory. Make sure to use the device file
with the
Use efi_cp to copy the AUTO file from the original boot disk’s EFIs1 suffix, as it refers to the EFI partition:
efi_cp -d /dev/rdsk/cntndns1 -u /efi/hpux/auto ./AUTO

partition:
Copy the file from the current directory into the new disk’s EFI

Step 7.
volume group onto the desired physical volume. The logical volumes
must be extended in the same order that they are configured on the
original boot disk. Use the
determine the list of logical volumes and their order. For example:
Use the lvextend command to mirror each logical volume in the rootpvdisplay command with the -v option to
pvdisplay -v /dev/dsk/c0t0d0s2 | grep ’current.*0000$’
00000 current /dev/vg00/lvol1 00000
00038 current /dev/vg00/lvol2 00000
00550 current /dev/vg00/lvol3 00000
00583 current /dev/vg00/lvol4 00000
00608 current /dev/vg00/lvol5 00000
00611 current /dev/vg00/lvol6 00000
00923 current /dev/vg00/lvol7 00000
01252 current /dev/vg00/lvol8 00000
In this example, mirror the logical volumes as follows:
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c3t1d0s2
lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c3t1d0s2
lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c3t1d0s2
lvextend -m 1 /dev/vg00/lv0l4 /dev/dsk/c3t1d0s2
lvextend -m 1 /dev/vg00/lvol5 /dev/dsk/c3t1d0s2
lvextend -m 1 /dev/vg00/lvol6 /dev/dsk/c3t1d0s2
lvextend -m 1 /dev/vg00/lvol7 /dev/dsk/c3t1d0s2
lvextend -m 1 /dev/vg00/lvol8 /dev/dsk/c3t1d0s2
If
lvextend fails with following message:
“m”: Illegal option
then HP MirrorDisk/UX is not installed.
Step 8.
Update the root volume group information:
lvlnboot -R /dev/vg00
Step 9.
disk and that the boot, root, and swap logical volumes appear to be on
both disks:
Display the BDRA. Verify that the mirrored disk is displayed as a boot
lvlnboot –v
Step 10.
Specify the mirror disk as the alternate boot path in nonvolatile memory:
setboot -a path_to_disk
Step 11.
text editor:
Add a line to /stand/bootconf for the new boot disk using vi or another
vi /stand/bootconf
l /dev/dsk/c3t1d0s2
where
l denotes LVM.
