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! Ashish

Automatic Failover
I would like to use Veritas Cluster Server to achieve high availability and automatic fail over for my applications. These application are java applications with some services with the backend databases using Sybase The java applications can be broken into 2 parts : web layer and application layer. The underlying infrastructure will be in RHEL Linux for java applications and database (Sybase) My question is : is VCS supporting seamless automatic failover for the java services including database services without requiring manual intervention ? What i want to achieve is : after i setup active-passive for application layer, i expect the active node to automatically failover to passive node and immediately the passive node become active node

Need way to create VCS group attributes
We have long been able to create new VCS resource attributes using hatype and haattr commands. We would like to be able to create new group attributes. In our particular use case, we would like to create a temporary group attribute called SleepMonitor that someone with operator privileges can update. (similar to the TFrozen group attribute) We would set SleepMonitor to an integer time() value that specifies when our custom monitoring script will stop ignoring the state of a service group and alert the GroupOwner when something is wrong. We want this attribute to be temporary so that it doesn't clutter up main.cf or require main.cf to be updated when a user wants to sleep monitoring. The group attribute UserIntGlobal could work if it wasn't a permanent attribute requiring the VCS configuration to be open to modify it using administrator privileges. From time to time we come up with other ideas of things we could do that require new group attributes to be created. Having the ability to create new group attributes would be phenomenal. -Seann

Replacing node
hi, I am using VCS on two node cluster having OS Solaris 10 Sparc. One primary node is having 13 CPU, 52 GB RAM and secondary node is having 4 CPU, 20 GB RAM. In case of primary node failure, secondary node is unable to handle the load. So we want to replace the secondary node with the same capacity as primary. The new node which I am preparing is from same hardware family having 16 CPU, 64 GB RAM. I have installed OS on it. My question is about the VCS installation and configuration on new node. What should be correct process of VCS installation to make new node as exact replica of secondary node with minimal downtime? Please revert ASAP. Thanks Amit

HAD unregistration problem with gab (failed) : VCS 6.0
Dear Team, I'm a newbi here. We have a VCS setup on two linux (6.4) nodes (SFCFSHA 6.0). When customer tried to reboot a master node, the following error messages (confirming that HAD has unregistered with VCS (retry 1) FAILED) appeared on iLOM and it caused the panic on slave node too. Now the node is up and everything looks okay. But we have to find out the cause for this error message. Please check the attached file for screenshot of the error message. Looking forward for your help. Thanks and Regards Barani

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.

LVM + multipath + diskreservation on VCS 6.2
Hello I have questions about the usage of LVM with multipath on VC 6.2. In our environnement we have : VCS 6.2 (I don't have storage fundation) The nodes are virtual machine with redhat 6.5. The iscsi lun are presented from netapp cluster cmode using ALUA. On the redhat nodes we use the default multipath tools => device-mapper-multipath. We use LVM on the luns. The document say the diskreservation is not supported on multipath. Can someone just confirm me that ? I would like to know if there something to replace diskreservation to prevent lun to be monted from 2 nodes in the same time in my situation. I know I can use lvm tagging but I not sure it's really a good protection. Any suggestion is welcome. Regards Mickael
