‘vxdmppr’ utility information
Hello, With VxVM, we get ‘vxdmppr’ utility which performs SCSI 3 PR operations on the disks similar to sg_persist on Linux. But we don’t find much documentation around this utility. In one of the blogs we saw that its unsupported utility. Can someone throw light on it. Has someone used it in the past? Or does anyone know how this utility is getting used in VxVM? How to know if this is supported or not? Rafiq
NFS agent for CFS share
Dear All, I have setup CFSshare. I can see under cfsshare display, but if I run "cfsshare share /emm2 rw" is NOT sharing but from the Java Console of the cluster. The NFS resource has got a question MARK. So I am really not too what to do now., root@node_1# cfsmount /emm5 rw Mounting...

Oracle Data Base Replication with VVR under SFCFSHA/DR
Hi All; we are looking for whether VVR can use for the oracle database replication instead of oracle data guard solution. If it is used, do you know veritas gives support for any problem faced. even VVR keeps the write order fidelity, it is not certain the database integrity will ve preserved at the disaster site. do you have any best practices and white papers, experience, anything you suggest for this deploymeny?
How To Manage Multiple VCS Clusters from a Central Location
What is the preferred tool/process used to manage multiple VCS clusters? We have several clusters in our environment and to date, the administrators RDP to one of the nodes in the cluster, open the Veritas Cluster Manager - Java Console. What is the solution to see all clusters in a single window or dashboard and also get notification of cluster events? Where is the documentation of how to setup the solution? Are there any videos that demonstrate how to setup or how the solution works?upgrade Storage Foundation and VCS 4.1 to SFHA 6.X
HI All, I'm going to upgrade my production environment with VXVM,VXFS and VCS 4.1. My question are: 1) After upgrade to Solaris10 up11, it's possibile to remove all Veritas packages and reinstalling everything at version SFHA 6.1 (and recover vcs configuration)? Does it support? 2) I see from Admin Guide this extract: Currently, only the Version 7, 8, 9, and 10 disk layouts can be created and mounted. The Version 6 disk layout can be mounted, but only for upgrading to a supported version what does it mean? Thanks in advance RickSFHA Solutions 6.0.1: Troubleshooting unprobed resources in Veritas Cluster Server
Veritas Cluster Server (VCS) monitors resources when they are online and offline to ensure that they are not started on systems where they are not supposed to run. When you configure VCS, you should convey to the VCS engine the definitions of the cluster, service groups, resources, and dependencies among service groups and resources. VCS uses the following two configuration files in a default configuration: main.cf—Defines the cluster, including service groups and resources types.cf—Defines the resource types For more information about configuring VCS using VCS configuration files, see: About configuring VCS About the main.cf file About the types.cf file VCS mainly fails to probe the resources or service group during following scenarios: When a new types.cf file is not copied into the /etc/VRTSvcs/conf/config/ directory duringa a VCS upgrade. If VCS fails to probe the resources, the service group does not come online and also gets auto-disabled in the cluster. This happens due to old types.cf files in the /etc/VRTSvcs/conf/config/ directory. When the definitions of the cluster, service groups, resources, dependencies, and attributes remain undefined or incorrect in the main.cf file. This causes configuration errors, and a STALE_ADMIN_WAIT message is displayed. When the installation of an agent for a specific node has failed. When a resource returns the resource state as “UNKNOWN”, which means the agent or resource is unable to monitor the configured resource. When the resource is disabled. For more information on probing the resources or service group, or troubleshooting service groups, see Probing a resource Service group not fully probed Service group autodisabled Some of the probing issues can be resolved by copying the latest types.cf file from the /etc/VRTSvcs/conf/ directory to the /etc/VRTSvcs/conf/config/ directory as follows: 1. Stop the cluster onall nodes: # hastop -all –force Applications continue to run, but do not fail over. 2. Back up the original types.cf file: # mv /etc/VRTSvcs/conf/config/types.cf /etc/VRTSvcs/conf/config/types.cf.date 3. Copy the types.cf file: # cp /etc/VRTSvcs/conf/types.cf /etc/VRTSvcs/conf/config/types.cf 4. Verify that both types.cf file are of same size: # ls -l /etc/VRTSvcs/conf/types.cf # ls -l /etc/VRTSvcs/conf/config/types.cf 5. Start the cluster on the node: # hastart You must execute the hastart command on all nodes in the cluster, and also verify that the types.cf file did not revert to the original version. If so, then repeat the procedure and shut down the Low Latency Transport (LLT) and Global Atomic Broadcast (GAB), after you execute the hastop command. You can also find information about probing resources and troubleshooting service groups in the PDF versions of the following guides: Veritas Cluster Server Administrator’s Guide Veritas Storage Foundation and High Availability Solutions Troubleshooting Guide VCS documentation for other platforms and releases can be found on the SORT website.
