Install and configure guide

[shabash]

i have 2 servers with same spec and oracle application is installed.
i am new to cluster envirnment and want to install and configure 2 node cluster locally from scratch.
Both system running hp-ux11i v3.
Is there any step by step guide to follow for cluster to install and configure??
can anyone help about?
i have search on the docs.hp.com but didnot find the install and configure guide??
can any one help???

[Duncan Edmonstone]

well you didn't search docs.hp.com very well then:

Installation instructions are in the release notes (although depedning on what was purchased you may find Serviceguard is already installed):

http://docs.hp.com/en/B3935-90124/ch01s04.html

everything on configuring Serviceguard:

http://docs.hp.com/en/B3936-90122/index.html

Seriously though, learning on the job is generally *not* a good idea when it comes to building clusters. Badly configured clusters created by inexperienced admins typically have worse availability than just single nodes. I'm not questioning your skills and abaility, I've just seen too many good admins think they can configure this right without understanding the consequences of the decisions they are making along the way.

My advice would be to:

i) Take the Serviceguard course available from HP - and/or:
ii) Get a Serviceguard consultant in to help you build the cluster

Hi,

Check the .dtprofile ( CDE user-specific script that executes at CDE login. )
if possible copy from 1 node to 2nd node.

What is the error message you are gettin

Check in /etc/nsswitch.conf the following entry is available

hosts: files dns
ipnodes: files dns

Check if xfs is running

Edit /etc/rc.config.d/xfs
RUN_X_FONT_SERVER=1

# /sbin/init.d/xfs start

Add the Windows host and IP address in /etc/hosts



Please assign point to your thread

can you check at first as whether the node starts up the CDE and you can notice the login screen by connecting a graphical monitor.

Else, please run
#dr_dt
on the node where the CDE screen is not coming up
and check for the output log to find out the reason.

Also note: by default CDE is not installed on HP-UX by default

Please check if CDE is installed on the HP-UX hosts

# swlist -l product| grep -i cde

[shabash]

when i grep it.

it shows me
CDE B.11.31 HP-UX CDE User Interface

Now the other working machine also show the same product installed.

But when i compare with working one

the /etc/rc.config.d/desktop(desktop is not present)

/usr/dt/bin/dtconfig -e(the bin is not present)

show i reinstall from cd or do wht???

[Duncan Edmonstone]

Well first I'd determine bwhat is different bewteen these two systems (after all if you want to cluster them you want the OS installs to be _identical_)

Luckily HP-UX11iv3 has the extremely useful sysdiff utility to compare the software configuration of 2 systems. From either system just run:

sysdiff

obvioulsy inserting the correct hostname. This should help you determine all the differences at the installed software level between the systems.

[shabash]

you sysdiff onenodeip and secondnodeip

run in of the machine or other machine present in the network

[shabash]

The SMH is working.

there is a option available as x-terminal conifguration?etc...
what should that be used for??

[Duncan Edmonstone]

>>you sysdiff onenodeip and secondnodeip

>>run in of the machine or other machine present in the network

Sorry what does that mean? Are you trying to say one node isn't on the network???

Duncan

[shabash]

Do i need to reinstall the CDE on the server not working for x-manager from window?

As far up till now nothing is working.

[Duncan Edmonstone]

possibly you will have to.

What do you get from running:

swverify CDE

on the broken system?

It might take a while to run.

Hi shabash,

CDE is NOT installed by default with HP-UX 11iv3. you may need to install this from the original install CDVD's
