How will this affect the OS..

I have OS installed on this path.

* Setting primary boot path to "/dev/rdisk/disk10".
Primary boot path set to 1/0/2/2/0.0x4.0x0 (/dev/rdisk/disk10)
* Starting install of the source (HP-UX Core Software).

Does it mean the the OS is installed on this disk which is external to the server.

In this case I want the OS on the Internal drive of thee server.

Well if you say that disk (disk10) is external than...yes that is being set as the primary boot path.

But couldn't you let it go that way and then when it's done set up your boot mirror disk on an internal disk, and then switch the boot paths order afterwards.

Just a thought,
Rita

thats a good idea...

how to set up boot mirror disk on an internal disk.Is there a command to do this ??

David ,
Check this commands to mirror the boot disk: (Source Disk) , to another disk (Target Disk):

In the below example you have to enter SOURCE_DSK and TARGET_DSK details ,

################
#Enter the Target and Source disk "
TARGET_DSK="diskXX" #Example : disk12
SOURCE_DSK="diskYY" #Example : disk13

>/tmp/partfile ; echo "3 \nEFI 500MB \nHPUX 100% \nHPSP 400MB" > /tmp/partfile ; cat /tmp/partfile

idisk -wf /tmp/partfile /dev/rdisk/$TARGET_DSK

idisk /dev/rdisk/$TARGET_DSK

insf -eC disk

ioscan -efnC disk
efi_fsinit -d /dev/rdisk/$TARGET_DSK'_p1'

mkboot -e -l /dev/rdisk/$TARGET_DSK
> /tmp/AUTO.lq ; echo "boot vmunix -lq" > /tmp/AUTO.lq ; cat /tmp/AUTO.lq

efi_cp -d /dev/rdisk/$TARGET_DSK'_p1' /tmp/AUTO.lq /EFI/HPUX/AUTO

>/tmp/x1 ; efi_cp -d /dev/rdisk/$TARGET_DSK'_p1' -u /EFI/HPUX/AUTO /tmp/x1 ; cat /tmp/x1
pvcreate -fB /dev/rdisk/$TARGET_DSK'_p2'
vgextend vg00 /dev/disk/$TARGET_DSK'_p2'

strings /etc/lvmtab | head -n 5 ; echo ""

#checking EFI details on both disks:

efi_ls -d/dev/rdisk/$TARGET_DSK'_p1' EFI/
echo ""
efi_ls -d/dev/rdisk/$SOURCE_DSK'_p1' EFI/
echo "----------------------------------------"

hi,

that mirroring procedure may or may not be right for you?

first you need to have the mirrodisk/ux software installed? have you? without this you cannot mirror like this

then do you have PA or IA type architecture server?

mirroring procedure is different for both systems

David,

What system do you have ,
Can you provide the output of :

# model
# swlist -l bundle | grep -i hpux | grep OE
# uname -a

* * Also make sure you have assigned points to all the responses who tried to help in this thread, and before closing the thread.

Cheers,
Raj.

Re: Primary boot path

this is an Integrity servers.... plz give me the procedure

Re: Primary boot path

David Willams — Fri, 28 Aug 2009 19:10:33 GMT

model : rx7640
OS : 11.31

Re: Primary boot path

Raj D. — Fri, 28 Aug 2009 19:29:44 GMT

David,
The above procedure given is for 11.31 Integrity server, root disk mirror. Be careful to specify the source and target disk. Source is the current disk system is booted from.

Source Disk is the current boot disk.
lvlnboot -v vg00 , will show the current boot disk.

- Also string /etc/lvmtab , check the disk under vg00 , that is the current boot disk.

- You can pickup the other disk for mirroring from the internal harddisk (ioscan -fnC disk ) , and go ahead with the mirroring steps.

Cheers,
Raj.

I have the above and when my system boots up.... it picks on 11.23 instaed of 11.31...

when I go to efi and go to fs1>hpux ... now it goes to 11.31...

So looks like some thing to do with the booth path...

Now I want the system to pickup 11.31 and not 11.23...

Re: Primary boot path

Raj D. — Fri, 28 Aug 2009 20:19:49 GMT

David,
If the disk9 is having 11.31 , so it has to be set as primary boot disk. Which is currently not.

As per the above setboot output it is pri boot disk refering to disk6.

You can do below to set pri boot path:

# setboot -p /dev/rdisk/disk9

To check again with:
# setboot

Cheers,
Raj.
