Hi,
We are going to perform a scheduled reboot in the primary node which is serving only one service group.
We do not want to switch over the SG to the backup node while the node gets rebooted.
How to do that. I heard that while rebooting the primary ndoe vcs 5.0 will invoke hastop -local -evacuate ..so i tried to disable the autoevacuate in the SG.
I set autoevacuate to 255 ( thought anyvalue greater than 0 will disable it). But it didn't worked . the SG failed over to next node while the server gets rebooted.
2. Disable the autofailover for the SG.
3.when i booked a case with symantec they suggested to freeze the sg temporarily or permamnently.
but as far as i know, Temporary freeze willl work till the had stops. so in that case the method will fail..so a permanent freeze of SG will help ?
4. The symantec engineer asked me to offline the sg, freeze it. and then do the reboot...- will it work ?
What is the VCS behaviour when i reboot the server manually..how to keep the...

Hello everyone,
We had a great meeting on Nov 18th with Mark Salmon presenting a technical review of Veritas Cluster Server (VCS) and the associated VCS testing tool called FireDrill. These are two really great products from Symantec that are definitely leaders in their space.
I have attached the two (2) presentations to this message for you to download and review.
Thank you again to Symantec for the excellent food and door prizes and we hope everyone has a wonderful holiday season with Thanksgiving and Christmas just around the corner. We will plan to meet again sometime around February next year to get everything off to a great start.
And don't forget, UserGroup members get an awesome $400 off Symantec Vision registration, a $175 MGM Gift Card, and a limited edition Symantec Vision jacket!!! Must register before March 12, 2010 and use the promo code: VISUG when registering.

Hi Gurus,
Currently i am using 2 servers each with 2 hard disks. as per veritas suggested, as i should not replicate the OS disk, i am installing my product on the second disk. Hence replicating only the second disk.
Now, I want to do one setup with same 2 server model, but only difference i want to replicate one partition alone. i.e., in C driver i have my OS and D drive in which i am going to install the prodcut which has to be replicated. and both these drives are placed under the same Hard disk.
is anyone made setup like this so far ? IF so can you guide me how to do this ?
Thanks,
Sri

Excuse me if this is answered elswhere; my limit for searching and poking sprawling forums and knowledgebases for answers is 1 hour.
It appears there is a fundamental change in the management software between these two versions. Version 5.0 doesn't seem to require an "Authentication Broker," but version 5.5 (included in the 5.0 VCS installation CD) does.
Is there any risk that the 5.0 VCS console is going to go unsupported? We'd like to avoid the time and hassle of implementing the broker (bloater?) service required for the 5.5 console. For the limited number of clusters we support it's absolutely not necessary.
Thanks in advance!

Hi Gurus,
I have a question related to Veritas Cluster 5.0. I have configured HA setup using two nodes. I have installed my prodcut in both the nodes. Now I can access my product using the Virtual IP address. But the fact is my product runs based on the server hostname. So as like as Virtual IP address , if there is virtual hostname then i dont want to install product on both the nodes. Instead i can use a storage array in between and install prodcut on that storage array using virtual hostname which is created when configuring the cluster.
Can anyone help me on this problem.
With Regards,
Sri

Hi all,
I have installed a VCS version 5.0 MP3 on a two RedHat EL 5.3 64bit nodes, this servers share four SAN disks that are connected by two fibre channel on each server, the multiple links with the SAN are managed with linux multipath daemon.
I have configured two types of resources in a one service group: Volume group and File system. The cluster, at the boot time, should import the Volume Group (and activate the logical volume that it contain) and mount the filesystems that is associated with the logical volume. This steps works fine without problems and the Volume group and File system start correctly and works fine, but, after some minutes, these resources do an auto-switch on the second node without reason.
In the engine.log I can see this at the switch time :
The first message speak about a resource "oradbvg" (is one of my shared volume group) that became online on the second node, but I don't start the resource on the second node.

We are currenlty researching Veritas Cluster Server as a potential candidate for a clustering solution for our product.
Our application uses:
Microsoft Windows 2008 Server standard edition.
SQL Server 2008 standard edition.
Microsoft .Net framework 3.5 WCF services on net.tcp and net.pipe protocols
We are trying to figure out whether Veritas Cluster server supports all above these?
Also please suggest any online resources/ebooks on cluster server that will help us for head start on this.
Thanks very much for your valuable inputs.

I have an HA-Oracle environment, and I am adding in HA-Tuxedo to cluster Peoplesoft Enterprise Servers. I've followed the manual and created the appropriate environment files and can bring up the process schedulers successfully outside of VCS, but when I try to online the Tuxedo resources, they become faulted. It appears from the VCS logs that the monitor process does not find the required processes and bails out, faulting the resource. I do see the error messages seen below in the Tuxedo log (not the VCS tuxedo log).
Thoughts? Thanks in advance.

Hi guys,
i´m implementing a enviroment with VCS 5.1 for Windows and Netbackup with GCO and one node by site. I´ve a doubt about the Lanman configuration. Each node belongs to one different subnet.
(node 1 = 10.x.x.x , node 2 = 172.x.x.x)
What configuration must apply (in the Lanman, I think) for the clients respond when the master server is online in site 1 or site 2.
Thanks,
Diego.

all,
a customer has a 2 nodes cluster VCS5.0 with AIX 5.2.
His goal is to go to AIX 5.3 TL9
then we need before to upgrade to VCS5.0 MP1
After upgrading in MP1 everithing fine !
Then migrating from AIX 5.2 to 5.3, here appears the problem : each time the 2 nodes see themselves then one of both hangs...
Because of production, now one is Running and the other is stopped.

Hello,
I have a cluster of one server with internal disks, because I will replicate this to secondary location and have global cluster (with only 2 servers)
I will run Oracle there.
I created disk group on internal disks using "vxclus usesystembus on"
But when I run Oracle agent configuration wizard, I get Error V-16-13-6529, that there is no shared volume
Any suggestions on how to configure Oracle cluster on internal disks ?
thank you

Hi.
As part as my company solution we are using the Veritas Solution to provide HA for our Server SW.
I was looking into an option to use the same Veritas Technology to provide HA when I dont have 2 physical servers and use VMware VMs.
Is that possible?
Since the VM can be configured to use as many NICs needed I was wondering if this is even a problem...
Are there any special configuration that are different from using physical machines?
The main idea behind this is for a Lab not Production.
Thanks in adavance.

Hi all,
I try to create a rule that starts after a SG comes online.
In Cluster Server Management Console I created a Notification Policy and a perl script. (Create a file, nothing difficult)
When a SG comes online the test.pl script does not run.
What am I doing wrong?
All help appreciated.

I will like to find out if anyone knows why this happens and if it is normal. After successfully replicating 72000000 blocks of data from primary to secondary site, replication stopped and it gave error connecting to the secondary site. Finally i successfully connected to secondary site and discovered i had 75000000 blocks of data pending, and status is showing resynchronising data.
Has anyone faced this issue? Could anyone advice on this issue?

I need to build a Disaster Recovery using Veritas Cluster and VVR. I need to have HA on Oracle 10g and Tomcat. This should be cheap as possible. This is not so data-intensive application.
This would be only 2 servers setup. I will have 2 clusters. Each with 1 server. I will use local disks. Then there will be replication between and having a Global cluster.
This are the only 2 servers on network with no domain or DNS. So one of these servers should be DNS and Domain. I think the backup server should be domain and DNS server. Is this OKay ? Or the domain server should be on third server or both servers ? Isn't this (domain and DNS) a single point of failure ? I am not sure how to setup this.
I will use 5.1 VCS HA with VVR on Windows 2003 R2 SE. Any help or idea appreciated.
