discussion comment 15 Feb 2011

Roger Zimmermann commented on: vxdg import failing with cloned disk

Did you clone all disks on the EMC? Means: is it possible that you increased the EMC configuration by some disks since the last sync? It looks like some of the EMC disks are not sync'd completely, so some private regions are missing. Saw this ...

Roger Zimmermann commented on: can i share swap in nfs

Swap space is disk space where the process manager puts main memory pieces to provide more available RAM to the online processes. Swap space has no internal structure, the process manager (or to be more accurate: the memory manager of the ...

Roger Zimmermann commented on: Urgent Help on VCS cluster

Hi, RBK001, is it possible that you talk about an IP adress somewhere out on the network when you say "reference IP", and if this one is not available, the cluster is switching the service group to another node? Then you can find ...

Roger Zimmermann commented on: Getting to know VCS using Vmware vSphere

There are no differences between physical and virtual servers for VCS except the following: If you use virtual disks in the virtual machines you have to take care for the following things: - no fencing is possible - all virtual disks have ...

Roger Zimmermann commented on: error about ps -u in the engine.log when config monitorprocesses of the APPLICATION resource.

Hi, did a little research today. Like pgm10s mentioned above there is no problem in AIX 5.3 and SFHA5.0 MP3. And because I cannot beleave that AIX 6.1 has a change in ps command (at least not that significant) I suspect there is a bug ...

Roger Zimmermann commented on: error about ps -u in the engine.log when config monitorprocesses of the APPLICATION resource.

Hi, it looks like the parameters for the -o option (demands a user list) are not passed to the ps command, therefore it tells you "ps : invalid listing of the -u"... There have to be a way to provide the correct user to ...

discussion comment 21 Dec 2009

Roger Zimmermann commented on: Dependence between Service Groups in Disaster Recovery solution.

Hi, mflores, first question from my point of view is, why you want to switch both application parts to the other side in case of a failure in one of them. If only one application fails and switches to the other site, the network connect should ...

Roger Zimmermann commented on: VCS 2 Nodes only start SG2 if SG1 is on node0

Hi, eshaffer, remote groups are not very usfull in this case. But there is a running solution for your problem. This only has two restrictions: 1. SG1 is not manually switchable, of SG2 is running on the same node as SG1 (means on C0), you ...

Roger Zimmermann commented on: Is virtual host name created in cluster

Hi, Sri, which version of solaris you are working with? There are Solaris Virtual Machines called Container in Solaris 10 and per Patch also in Version 9. With this you can do the following: - make a Solaris Container, probably one that ...

discussion comment 11 Nov 2009

Roger Zimmermann commented on: N-to-1 configuration

Hi, ryan, you can configure things like this with Limits and Prerequisites, where Limits is an attribute to a node and Prerequisites is an attribute to a service group. Limits are hard borders what must not crossed, so you cannot ...

discussion comment 11 Nov 2009

Roger Zimmermann commented on: Using Veritas Cluster for 2 VMWARE guest Servers VM.

Hi, damrani, there is a limitation for the cluster environment in virtual machines. You cannot use SCSI III Persistent Reservation for the fencing mechanism if you use VMware ESX 3.5 or earlier or if you do not have any direct ...

Roger Zimmermann commented on: adding a node to a service group

Adding a node to a service group: Look if you can see the new node via GAB (gabconfig -a). If the node is visible: GUI: right click on the service group -> view -> properties view -> show all attributes -> SystemList (edit ...

discussion comment 01 Jul 2009

Roger Zimmermann commented on: Maximum numbers of nodes in VCS 3.5 for HPUX?

Hi, Imiao, this "Clusters up to 32 nodes are supported" is only the maximum number of nodes you can configure in the High Availability Engine. It depends on the hardware and your network bandwith, up to which number of nodes your ...

Roger Zimmermann commented on: Global cluster replication and changing storage

Hi, Tomislav, there are two ways to do this with only Storage Foundation mechanisms. The first one would be to make on the primary side an additional mirror to your existing volumes living on the new storage device. After syncing to the ...

Roger Zimmermann commented on: SAPNW04 behaivior in failover an Enqueue Replication Server

Hi, Manuel, sorry for the delay, was busy with some other installation. Two things: First it is possible that the attribute EnqSrvResName in the ASCS ressource should not be set, I will correct this. But on the other hand I was not able to find ...

Roger Zimmermann commented on: SAPNW04 behaivior in failover an Enqueue Replication Server

Hi, Manuel, sorry for the delay, we were busy with going productive the last days. Yes, preonlinig is allowed for both instances and the EnqSrvResName attribute is set as well. But nevertheless the failover to the last remaining node takes place. ...

Roger Zimmermann commented on: SAPNW04 behaivior in failover an Enqueue Replication Server

Hi, Manuel, Thanks for the answer. Yes, my main.cf looks very similar like the mentioned one. And all the stuff is running well as long we have enouch valid nodes for the service groups SAP70-ASCS and SAP70-REP. But when all nodes are failed and ...

Roger Zimmermann posted: SAPNW04 behaivior in failover an Enqueue Replication Server

I need a solution We actually have a problem (or even an unclear situation) with the configuration of an enqueue replication server and an enqueue server in a SAP R/3 installation. Situation: - installed is a 3 node

discussion comment 12 Nov 2008

Roger Zimmermann commented on: Clustered file system / NFS Share

Hi, Legrandmeitre, I suspect that your NFS mounts on the third server are STALE after the switch inside the cluster? Please have a look in /etc/name_to_major on both of your cluster nodes, if the NFS driver have the same number inside. If the ...

discussion comment 11 Nov 2008

Roger Zimmermann commented on: VXFS Capacity ( df -h output )

Hi, JM, indeed this behavior is a little strange, especially if you try to find out the "real" available capacity of your filesystem. But all this has something to do with the inodes in the VxFS and the fact, that VxFS is extend based ...
