How to clean install 11.31 on vpar running environment ?

[public]

Hello all,

I have a question that want to have a clean installation of 11.31 (DVD installation) on vpar running environment ?

Current, I have npar with 5 vpar systems, I already upgrade one vpar environment from A.05.05 with HP-UX 11.31, others still in 11.23 with vpar A.04.03 version. Now, I want to have a clean install another vapr (11.23 OS) to HP-UX 11.31, I check the vpar admin guide below

Booting from HP-UX Install Media (Integrity only) Under vPars A.05.02 and later, the vPars
Monitor supports booting an install kernel from CD or DVD media with the vparload -p
partition_name -D disk_index command. For details, see “vPars Monitor: Using vPars
Monitor Commands” (page 135).

If this saying that I can use 11.31 installation DVD media to have a clean installation on my vpar environment ? And, how do I know where is the disk_index of DVD ? and last, if this clean installation will need a npar reboot ? or all task can be finished on vpar environment ? (I can't reboot npar because still have another vpar running systems)

thanks for your help on this

I would make a depot on the ignite server that contains your 11.31 release and vpars A.05.XX software.

then you can boot your vpar from ignite:

#vparboot -I

this way you can install 11.31 and the vpar software with 1 reboot.

" if this clean installation will need a npar reboot ? or all task can be finished on vpar environment ?"
I have been asking myself the same question, I am going to have a look..

I'm almos sure you don't have to reboot npar, but I'm going to check anyway

I think you can use -E option against disk_index, Ref the below link

Shalom,

In general, I would swcopy the Core OS 11.31 to an Ignite server. Then do a network install of the OS.

Here is a guide for the setup process.

thanks all, I know I can use Ignite-UX, but it need to build a Ignite-UX server, Customer did not have another for me to build this.

So ... any idea if i can also do that via installation DVD ?

[public]

Hi Jitesh purohit,

I think the -E option still need the disk_index, how do I know the disk_index before issue the vparload or vparboot command ?

[likid0]

I'm not shure you can install the vpar(11.31/A.05) from DVD, without having to reboot to npar, beacuse once you finish installing the OS, it won't boot because it needs the vpar software...




-D disk_index
(Integrity only) Supported by vPars A.05.02 and later. Launches the install kernel from the CD or DVD media specified by disk_index. If the disk_index specified is â Xâ the install kernel is launched from the disk â fsX:â . If installable media is not present at the index specified, the virtual partition will be shut down and the user must select a different disk_index.
-E disk_index

(Integrity only) Launches the vPars boot helper EFI application from the disk specified by the disk_index. The EFI boot helper prints the EFI paths of all the bootable disks belonging to the target virtual partition and prompts the user to select a disk to boot from.

Under vPars A.05.02 and later, if the disk selected is a CD or DVD device, then the install kernel from the media is launched instead of the regular kernel and any boot options specified on the command line are ignored.

[Steven E. Protter]

Shalom,

If I remember correctly you can make mount the DVD on a system, and make it and NFS share. You might be able to boot from that.

This is a reference:
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01913755/c01913755.pdf (BSC link updated by admin)

Like my other answers they are for 11.11 but may apply to 11.31.

You could also copy the entire DVD to disk.

This is similar to a system recovery:
http://docs.hp.com/en/5992-5309/ch15s02.html

I guess I'd say allocating some disk space in a working system to create an Ignite server is not a terribly bad idea. It won't use resources other than some disk space.

You might also set it up on an older system on the same subnet.

Hi Daniel Parkes

But if I can install the vpar software when OS installation ? HPUX 11.31 VSE or DCOE will install vpar software as well.

[Steven E. Protter]

Shalom,

The vpar installs an OS. The only thing that is different in a vpar is the level of hardware control.

As noted by our co-poster, you can isntall a vpar off a shared DVD or a disk segment.

The vpar must be booted, and be able to see the location the media is sitting. If that media is DOCE, or MCOE, is not important at all.

Hi SEP,

my understanding is that if the vpar software not installed when OS installation, then I can't boot this vpar because no vpar software. just like vpar migration, I use update-UX command to upgrade OS and vpar software at same time. (I also can do this via clean install by choice the vpar software at installation time)

If the Ignite-UX can do an clean OS installation without install vpar software ? I don't think so.

[public]

Hi all,

thanks for you inpout for this topic, if really need a Ignite-UX server to do clean install, does anyone can porvide a detail step for this ?

I find the vpar white paper for create a golden image with Ignite-UX server as following URL, if this is the right step for build Ignite-UX server ? thanks.

Hy Public,

That's true if you have a media release that has the vpars soft included you should be fine.

the disk_index can be found with a the map command in the efi_shell:

Shell> map
Device mapping table
fs0 : Acpi(PNP0A03,0)/Pci(0|0)/Scsi(Pun2,Lun0)/HD(Part1,SigCA36301E-5257-11DD-8002-D6217B60E588)
fs1 : Acpi(PNP0A03,0)/Pci(0|0)/Scsi(Pun2,Lun0)/HD(Part3,SigCA363064-5257-11DD-8004-D6217B60E588)
fs2 : Acpi(PNP0A03,0)/Pci(2|0)/Scsi(Pun0,Lun0)/CDROM(Entry0)

CDROM has number 2 disk_index

As how to get it out of the vpars, you can do a #vparboot -p vpar -E 0

and when the vparboots is shows a map of the devices on the console, so you can then choose your dvd-rom

Hi Daniel,

Thanks, so if all installation task can be finished without reboot npar ? (I think only need to reboot vapr, that sure)

[Steven E. Protter]

Installation and configuration of an Ignite server or creation of a DVD or disk install point will not require a reboot of the npar.

It probably will not even require a vpar reboot.

OS installation into a vpar only requires a vpar boot.

Thanks Steven, I will try to install the 11.31 with vpar software A.5.05 tomorrow, hope everything is fine during the installation. there are three critical system in the other vpars, hope no any impact on those three systems

You can install the OS directly from the virtualization media set of 11.31 (core install). Just make sure you select the vPars software to install during OS install.

[Steven E. Protter]

No need to point this post.

It is possible that an install can go bad, hammer the vpar and take down the entire npar.

It is extremely unlikely, but things can go bad.

npar/vpar is designed to let you do this install, during the day, with production systems running in other vpars.

I rate the chance of a problem at less than 1%, substantially less than 1%.

I would feel comfortable proceeding with the install from the virtualization media on the Core OS DVD with only a notice to my user community that upgrades are in progress on non-production systems, there may be a minor performance impact.

If there are users unhappy about that, then you should schedule this for outside of prime production hours.

Just to add - make sure to read the manual again (about mixed 11.23 and 11.31 OS) and check if you meet all requirements!

[public]

Hi Torsten,

Thanks for the reminder, yes, the current vpar environment already mix the 11.23 / 11.31 OS version after I upgrade one vpar from 11.23 to 11.31 via update-ux command.

Now, the vpmon boot from 11.31 disk and then boot other vpar systems. so it should be OK when I cold install another vpar to 11.31. thanks.

[public]

Hi SEP,

Thanks for your point of view, I will let my customer know it will have a little bit performance issue on that time.

Dear all,

I just finish the installation tonight without any problem from DVD media, thanks for your input.
