Installation of Symantec's VCS fails on Linux 6.4 guest OS on a VMware host


Hello,

Installation of Symantec's VCS 6.0.2 on 2 Linux 6.4 guest OSs on an ESX host fails because the LLT/GAB network doesn't connect the two virtual machines. Either node can start a one node cluster, so the installation procedure was followed correctly.
The lltping and llttest utilities show no connectivity across the eth2 and eth3 interfaces. So, there must be some break or misconfiguration.
I need to know what links a VMware vSwitch construct to a guest Linux 6.4 virtual NIC?
TIA,
Bill

let me get this strait.
you are trying to make and run a VIRTUAL cluster ,and not a real one ?

and the two virtual nodes are ON the same HOST computer

also there is NO operating system called "linux 6.4 "

there is the NOT free RHEL 6.4
where you have to buy the required support contract
or
the Free rebuild called CentOS 6.4 or ScientificLinux 6.4
or a lesser known "clear 6.4"

Thank you, John.

You are right that I misstated the OS. Also, you are correct that the customer is building a VCS cluster of 2 virtual RHEL machines on a single ESX host. Their purpose is a Proof of Concept to a federal government agency concerning the high availability of an Oracle 11g database and an SAP application. This is not a production environment. Still, the build of a 2 node VCS cluster must have some, if not all. of the components in a state where they can be explained to the customer correctly.
As a consultant, I am not allowed to log onto the customer systems and must depend on the unverifiable statements originating from the surrounding cubicles that "the network is OK", etc. I can not, in fact, accept these statements. Thus, my question about what links the guest OS network interface to the host network interface. I've been investigating the configuration of VMware vSwitch and RHEL virtual network interface and have made progress in my understanding of the failure of the LLT/GAB network to connect the 2 virtual machines. So much for that.

What I need is a list of commands I can have the customer run which will show the network connections of the guest to the host from which, I trust, a mis-configuration can be found.

with RHEL a not free OS
The old Oracle 11g database also a not free database
The 12 g database is the current and 11 or 12 should ! be ran on Oracle's rebuild of RHEL
"oracle 'unbreakable' linux" ( also a not free OS ) . It is designed TO RUN their database very fast and very well
as in it is optimized FOR the 12 g database


and vmware a not free VM
have you contacted all 3 software providers

you do need support contracts from all 3

you need to build "bridges" for the vm's to contact the outside world
these are virtual network cards

this is a bit beyond my skill level
i only connect single virtual os's to the network.
getting "heartbeat" going on a VM ???? is not something i have done

i would start with VMware
-- RHEL 6
http://partnerweb.vmware.com/GOSIG/home.html
-- oracle 6
http://partnerweb.vmware.com/GOSIG/OL_6.html

and have a look at the vmware knowledge base
http://kb.vmware.com/selfservice/mic...s/microsite.do

you might also want to have a look at symantec's documentation and support
http://www.symantec.com/business/sup...inks_global_ts
and
