vpar Monitor upgrade.

[fizan]

Hi Experts,

Currently the v-par monitor version & partition:
vparstatus -P
Current Virtual Partition Version: A.04.05
Monitor Version: A.04.05

vpar1:A.04.05 11:23
vpar2:A.04.05 11:23
vpar3:A.04.05 11:23

***Now i need to have the 4th vpar as 11:31***
so i need to install the vpar monitor with
vPars monitor (A.05.01) deleting the(A.04.05)

vpar4:A.05.01 11:31 correct, if am wrong advice me.

for this needs to be done:

1. shutdown all running 3-Vpars
2. MON>reboot --- boot into n-par0 mode.
3. In the napr0 delete the monitor-sw(A.04.05)
4. Install the (A.05.01)monitor on n-par0
5. After that reboot to ISL>hpux /stand/vpmon
6. Load all 3 v-pars
7. Then create the 4th v-par from running v-par
8. Boot from tape.

Am bit worried:: Instead of deleting the
A.04.05 & installing this Sw A.05.01 is Migration possible for new vpmon--A.05.01

Thanks

Hi,

Do the below procedure:
1. shutdown & boot the system with 11.31 DVD-ROM. Install OS on new HDD (which will be allocated to new 11.31 vpar).
2. After os installation, install vpar A.05.01 software.
3. Then recreate 11.23 vpars.
4. Then boot the system back in vpar mode from monitor of 11.31 i.e. A05.01.

Please note: Always, you have to boot the 11.31 monitor first & then only you can boot the 11.23 vpars.
If you fail & 11.23 vpar monitor boots first, then 11.31 vpar won't be booted.

Hope, this helps you.

Thanks,
Vivek

The manual has several update scenarios, but your plan sounds reasonable too.

Better to cold install the 11.31 vPar in nPar mode, but your plan is also worth to try.

As said, the 11.31 vpmon (version 5.xx) must always be used in a mixed installation.

Vivek,

So i should get down to n-par0 & while try to load the 11:31 from the ignite tape, i should boot in the new Hard disk & after OS installation complete i need to install the new vpon A.5.0.1.

1.boot into n-par0
2.select the tape of 11:31 to install os on new hard disk
3.Install the A.5.0.1 in the neww hard disk.
4.then boot the server into ISL>hpux /stand/vpmon
5. start the 11:31 v-par first 4th -vpar.
6. start the rest 3 11:21 v-pars existing old.

[Vivek_Pendse]

Yes, exactly.
The vpdb will be re-created/over write on existing 11.23 vpars.
Here, your Master monitor will be always from 11.31 vpar. The resource allocation/modification, will only be done thr' 11.31 vpar monitor as it's master in mixed environment.

Tortsen,

can you help me to get clear idea on this::

"Better to cold install the 11.31 vPar in nPar mode"

can you share me some points how to perform this.

[fizan]

Vivek,

Thanks for your solutions,

still is it safe to proceed with this.
Can you clear me on this:

1.By default the vpar monitor vpmon> sits on the n-par right, after the v-par sw installed on the respective n-par ?

2.On n-par0 when v-pmon A4.5.7 is deleted & installed with A.5.0.1 whether the vpdb will automaticlly store all the old v-par configurations, after we boot into the v-par mode?

3.There will be any change in the monitors boot path bcoz now we are going to install the 11:31 on new disk, so path will change from old monitor path to this 11:31 disk path?

4.****Re-create of 11:23 v-pars? what should i perform here again after booting up the new A.5.0.1 monitor after start the 11:31 v-par, next is should build from scratch the other 3-v-pars of 11:23 do you refer this one?

Thanks

Hi,

vpmon never sits on npar..
It's like: suppose you have 4 os vpars on npar. Then, you have a choice to boot npar from any os (vpar). Then, vpmon of that os will boot.

And, cold installation is a installation either from DVD or from ignite-ux installation.

As mentioned, you have to shutdown the npar. Then boot the npar from 11.31 DVD & install OS on new disk (which will be assigned to 11.31vpar) & then install vpar sw of 11.31.
Then re-create all other vpars & boot them.

Hope, this helps you.

Thanks,
Vivek

You should read the chapter

Updating from vPars A.04.xx to Mixed HP-UX 11i v2/v3 vPars (A.04.xx and A.05.xx)
Environmentâ (page 100)

in the guide. This should help.


Install version A.05.07.

However, I would first create the 4th vpar. Then boot in nPars mode and install 11.31 together with vPars software on an empty disk. Then copy the vpdb file into stand.
Boot in vPars mode from this disk. You now should have all 4 vPars up.
