Can LLT heartbeats communicate between NICs with different device names?
One 2-node vcs cluster, the heartbeat NICs are eth2 and eth3 on each node, IF eth2 on node1 down, and eth3 on node2 down. Does this mean the 2 heartbeat Links both down, and the Cluster is in split brain situation? Can LLT heartbeats communicate between NIC eth2 and NIC eth3? Since the 《VCSInstallation Guide》requires the 2 heartbeat Links in different networks.We should put eth2 of both nodes in the VLAN (VLAN1), and put eth3 of both nodes in another vlan (VLAN2). So in this situation heartbeats cannot communicate between eth2 and eth3. But, in a production cluster system, we found out the 4 NICs--eth2 and eth3 of both nodes are all in a same VLAN. and this lead me to post the discussion thread to ask this question: IF eth2 on node1 down, and eth3 on node2 down, What will happen to the cluster (which isin active-standby mode)? Thanks!Solved1.6KViews5likes5Comments
SQL Server Service Group can't bring online on the second node
Hello everyone, Please I need a solution about my SQL cluster in test environnement. I have issues with the service group that I can"t bring it online on the second node. But in the first node its can be online without errors. For testing the intergity of the DATA on the ISCSI partition, I deleted the service group. And i mounted the partition on the second node, I recrated the service group, I can bring it online easily. When I switch it to the other node (first node on the cluster), same error, its can't be bring in online. Below some error on the event viewer about this problem : Thank you in advance for your helpSolved1.5KViews3likes5Comments

VCS system states in the state of ADMIN_WAIT
If you name the cluster name cluster while running VCW, then system states of all VCS nodes are going to the state of ADMIN_WAIT. If you try to start VCS with the "hastart -onenode" command after run "hastop -all", then hastatus will display "STALE_ADMIN_WAIT". Check the main.cf, you will see the cluster name is cluster. include "types.cf" cluster Cluster( UserNames = { admin = gJHkHEfFGjISjGFqJJeRJoJSiRJj } Administrators = { admin } ) system symantecha1( ) system symantecha2( )Solved1.5KViews3likes2Comments

When 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.Solved839Views2likes1CommentIntegrating 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?

Hello, On the purpose of testing the new version of Veritas cluster, I created 2 nodes that contains SQL server binaries. This 2 nodes are identical on configuration, and attachement to the SAN over ISCSI. On the official documentation, they recommand to make the DATA of the instance from the first node on the shared storage. And for the second node, they DATA can be reside on the local disk. I do this, but when I was configuring the service group, and when selecting the systems (nodes) that can participate on the cluster service group. An error message appears telling man that the nodes are not identical, and the seconde node can't find the instance. Can you please help me about this problem.
