After trying nPar on rx7620 machine stopped booting

[Makesh Annamalai]

Dear All,

I'm new to the nPars. I tried to do nPar on the rx7620 which has 2 cell Boards. I have followed the HP nPartition Administrator's Guide. Points guarenteed for valuable suggestions

I did the following later the machine doesnt boot.

Step 1 :

MP:CM> cc

This command allows you to change the complex profile.

WARNING: You must either shut down the OSs for reconfiguration or
execute the RR (reset for reconfiguration) command for all
partitions before executing this command.

G - Build Genesis complex profile
L - Restore Last complex profile
Select profile to build or restore: G


The genesis complex profile creates one single cell partition.

WARNING: The genesis complex profile automatically ENABLES partition
reconfiguration. This allows partitions to issue platform
reconfiguration commands that could affect other partitions.

Use the PARPERM command to disable partition reconfiguration.

Choose the cell to use.
Enter cell number: 0

Do you want to modify the complex profile? (Y/[N]) y

-> The complex profile will be modified.

Step 2 : -

MP:CM> bo

This command boots the selected partition.


Part# Name
----- ----
0) Partition 0

Select a partition number: 0

Do you want to boot partition number 0? (Y/[N]) y

-> The selected partition will be booted.


Later i tried to change the Complex by giving 1.

Tired resetting the partitions by giving RR & RS...Nothing helped...Now my machine either boots & allows to installs the OE from DVD.

The Output of CP command from MP :-

MP:CM> cp

--------+--+
Cabinet |0 |
--------+--+
Slot |01|

When i try to boot from DVD it throws the below error.

Selected boot option: DVD

Loading.: DVD

Press any key to continue


When i Boot from the harddisk it throws the below error..Pls help

The quorum disk is currently not connected to your partition - try to boot without quorum check.

hpux> boot -lq

[Makesh Annamalai]

Thank you so much ! I cud able to boot the server. But it is able to display only the devices in 1 cell board (eg) the machine has 8 processor But it shows only 4 .same case on the LAN card.

Pls find the Output & do the needful :-)

I don't know what you want to do, but you just created an nPar with cell 1 only.

Cell 0 is inactive (just like you configured that).


If you want to join cell 1 to the existing nPar, you need to use parmgr to add the cell to the current npar config.

[Makesh Annamalai]

Hi...

I need to Create another nPar...Have 4 vpar in 1st nPar & rest in npar2.

Can u help me in the steps of nPar alone ?

[Torsten.]

Are you sure doing the right steps already?

By creating a genesis partition you "deleted" the second cell from the npar.

You took away cell 0 from the nPar and all the CPU, memory and I/O (!) connected to that cell. You probably need to adjust your current npar related OS settings (pathes to disks etc.). Do you still need your vPars running? If, adjust everything first.

[Makesh Annamalai]

Its a fresh machine. So once the Npar is done..then i will do the Vpar on each nPars

[Torsten.]

So you need to create the second partition on cell 0 now using either

# parcreate

command or

system management homepage, e.g.

http://localhost:2301/parmgr
