VCS discovery windows
Hello Experts, As part of a monitoring solution, we have been relying upon the presence of below registry keys to detect presence of a VCS on Windows, HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\VC HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\VCS\Base This however seems to be unreliable leading to false positives. I want an approach(could be a registry key/value) to detect a VCS with certinity on a Windows. Thank you! Ashish1KViews0likes1Comment
VCS SAP HANA agent
Hello all! We have Replicated Data Cluster two nodes in local cluster. No global clustering. My questions now about our RDC cluster. I could not find all neсessary information in cluster pdf doc. 1. When the primary Site1 fails (or we switch over SAP IP vcs group manually ) the secondary Site2 becomes primary with Site 1 DB going down. Should the cluster agent start up Site 1 DB as secondary automatically or administrator must do it manually? 2. We must have three different IPs for RDC cluster : one virtual IP is for connections from applications (productive SAP IP) and two IPs for two nodes for data replication between primary and secondary databases. But we have no sample RDC cluster configuration with replication IPs. Why? This is strange because cluster must know about network replication status... 3. Is Replicated Data Cluster (RDC) really supported for SAP HANA Cluster Agent ? Could you give us a real working configuration example? Thank you very much! Kind regards , Pavel TsvetkovSolved1.1KViews0likes1Comment
Continuity after a failover
Hi, I am new to clustering. 1. If I create a cluster with 2 nodes and shared storage, and keep my application running on node1, client applications will be connecting to my application on node1. In the event of a failover, when the application starts on node2, will the client applications need to change the IP address to which they were connecting? Or will VCS show a single IP address to the external world so that client applications do not need to be reconfigured? 2. Can I configure VCS to start my application on node2 automatically in the event of failover, without any manual intervention?

Are we monitoring the right object?
Just some quick questions. We use Veritas Clustering for providing an HA solution for database servers. We have set up the vcs montoring to try to connect to the database every 3 minutes. After 4 attempts the VCS kills the primary pid and fails over to the other side. The box is self is fine, just vcs was unable to connect for whatever reason. The theory is that if the database is unresponsive for 12 minutes it must be in a hung state. Correctly or not, there are many reasons that a database might be unresponsive other than hung. My question is this, should we be checking the host (hardware) not the database for whether or not to fail over. What are other companies that use VCS for HA doing to ensure that failovers do not happen for unnecessary or unintend reasons? Is VCS intended for checking application availability?

Integrating SAP with VCS 6.2 (on Oracle Linux 6.5)
Hi, I was wondering if someone has some additional information regarding how to setup my cluster... I have both VCS (inclusing Storage Foundation) and Linux knowledge. I do however have no background in SAP. And as SAP is a very complex product, I can not see the forest because of the trees... Setup 2 node (active-passive) cluster of Oracle Linux 6.5 nodes. Veritas Storage Foundation HA (= VxVM + DMP + VCS). Oracle 11.2 as database. SAP ECC 6.0 Apart from the Installation & Configuration guide on the SAP NetWeaver Agent, I found little information about implementing SAP in VCS. Source: "Symantec™ High Availability Agent for SAP NetWeaver Installation and Configuration Guide for Linux 6.2". But unfortunately I can not find a howto, guide or whatever from Symantec, nor from the usual Google attempts. My customer is however also not very SAP knowledged. From what I understand it is a very basic SAP setup, if not the simplest. They are using SAP ECC6.0 and an Oracle 11.2 database. So I assume they are just having a Central Instance and the Database. After some Google resource, I found out that SAP ECC 6.0 is technically a SAP NetWeaver 7.0. On Symantec SORT, I found 3 versions of SAP NetWeaver. I downloaded the first one, as the descripton says: SAP NetWeaver SAP NetWeaver 7.1, 7.2, 7.3, 7.4 SAP NetWeaver 7.1, 7.3 Agent: SAPNW04 5.0.16.0 Application version(s): SAP R/3 4.6, R/3 Enterprise 4.7, NW04, NW04s, ERP/ECC 5.0/6.0, SCM/APO 4.1/5.0/5.1/7.0, SRM 4.0/5.0/7.0, CRM 4.0/5.0/7.0 Source: https://sort.symantec.com/agents/detail/1077 SAP ERP 2005 = SAP NetWeaver 2004s (BASIS 7.00) = ECC 6.0 Source: http://itknowledgeexchange.techtarget.com/itanswers/difference-bet-ecc-60-sap-r3-47/ Source: http://www.fasttrackph.com/sap-ecc-6-0/ Source : http://wulibi.blogspot.be/2010/03/what-is-sap-ecc-60-in-brief.html Currently I have this setup unfinshed: Installed & configured Storage Foundation HA on both nodes. Instaled the ACC Libraries on both nodes. see: https://sort.symantec.com/agents/detail/1183 Installed the SAP NetWeaver Agent on both nodes. see: https://sort.symantec.com/agents/detail/1077 Configured next to the CusterServiceGroup, 3 Service Groups: SG_sap the shared storage Resources: DiskGroup + Volumes + Mount. the SAPNW Agent Resource. SG_oracle the shared storage Resources: DiskGroup + Volumes + Mount the Oracle Agent Resurce. SG_nfs still empty. SAPNW Agent. SAP instance type The SAPNW Agent documentation states: The agent supports the following SAP instance types: Central Services Instance Application Server Instance Enqueue Replication Server Instance. Source: "Symantec™ High Availability Agent for SAP NetWeaver Installation and Configuration Guide for Linux 6.2" But I guess the SAP ECC 6.0 has them all in one central instance, right? So I only need one SAPNW Agent. How is the SAP installed: only ABAP only Java add-in (both ABAP and Java). Source: "Symantec™ High Availability Agent for SAP NetWeaver Installation and Configuration Guide for Linux 6.2" I have no idea. How can I find this out? InstName Attribute Another thing is the InstName Attribute. This also does not correspond with the information I have. My SAP intance is T30. So the syntax is correct more or less, but it isn't listed below. Which is important also to decide on the value for the ProcMon Attribute The SAPSID and InstName form a unique identifier that can identify the processes running for a particular instance. Some examples of SAP instances are given as follows: InstName = InstType DVEBMGS00 = SAP Application Server - ABAP (Primary) D01 SAP = Application Server - ABAP (Additional) ASCS02 = SAP Central Services - ABAP J03 = SAP Application Server - Java SCS04 = SAP Central Services - Java ERS05 = SAP Enqueue Replication Server SMDA97 = Solution Manager Diagnostics Agent Source: "Symantec™ High Availability Agent for SAP NetWeaver Installation and Configuration Guide for Linux 6.2" In the listing of the required attributes it is also stated. However, the default value is CENTRAL. I guess this is correct in my case? InstName Attribute: An identifier that classifies and describes the SAP server instance type. Valid values are: APPSERV: SAP Application Server ENQUEUE: SAP Central Services ENQREP: Enqueue Replication Server SMDAGENT: Solution Manager Diagnostics Agent SAPSTARTSRV: SAPSTARTSRV Process Note: The value of this attribute is not case-sensitive. Type and dimension: string-scalar Default: APPSERV Example: ENQUEUE EnqSrvResName Attribute A required attribute is the EnqSrvResName Attribute. The documentation says this should be the Resource Name for the SAP Central Instance. But I am assuming I only have a SAP Central Instance. So I guess I should use the name of my SAP Agent Resouce from my SAP Service Group? EnqSrvResName Attribute: The name of the VCS resource for SAP Central Services (A)SCS Instance. This attribute is used by Enqueue and Enqueue Replication Server. Using this attribute the Enqueue server queries the Enqueue Replication Server resource state while determining the fail over target and vice a versa. Type and dimension: string-scalar Default: No default value Example: SAP71-PI1SCS_sap Source: "Symantec™ High Availability Agent for SAP NetWeaver Installation and Configuration Guide for Linux 6.2" Is anyone able to help me out? Thanks in advance.Solved2.4KViews2likes9CommentsWhen can 'hasys -nodeid' fail?
Dear All, We are running VCS Engine version 6.1.0.000 and need to use 'hasys -nodeid' to get info about the node. So in what scenario can this command fail ? Also in VCS 6.1 . , the man page info for this command states that it will display the nodeid value for the corresponding system if the nodeid is supplied whereas in older versions it states that itwill set the supplied nodeid . Can anyone confirm the behaviour when the nodeid is supplied as well please ? Thanks in advance.Solved839Views2likes1Comment
VCS Setup - "Install A Clustered Master Server" Greyed Out
I originally posted this in the NetBackup forum but it seems to be a VCS issue that is the root of the problem: https://www-secure.symantec.com/connect/forums/install-clustered-master-server-greyed-out I am trying to set up a test NBU 7.6.0.1 master server cluster with VCS on Windows Server 2008 R2but the option to "install a clustered master server" is greyed out. I have built2 new servers, installed SFHA / VCS 6.0.1and configured disks / volumes / disk groups / VVR replication. The VCS installation has not been modified or customised in any way as from my understanding the NBU installation will create its own service group. I have carried out the initial configuration and added the remote cluster node. Within cluster explorer, the defaultClusterService service group is all up and running, the global cluster option is enabled andthe remote cluster status also shows that the other cluster is up. Marianne has alreadyasked me to run two commands with the following output: 'gabconfig -a' - "GAB gabconfig ERROR V-15-2-25022" lltconfig -nvv - "LLT lltconfig ERROR V-14-2-15000 open \\.\llt failed: error number: 0x2" I've probably just made a silly mistake somewherebut I can't figure outwhat piece of the puzzle I have missed - any ideas?Solved4.6KViews1like37Comments
