My good buddy Scott Schnoll attempts to clear up some confusion on when and where to use Cluster.exe/CluAdmin to move a CMS. Find his post here: http://msexchangeteam.com/archive/2007/10/22/447317.aspx Here is the comment I left: The samples you sited are for creating or managing a cluster, none of them are for moving a CMS. Using CluAdmin/Cluster.exe vs. EMC/EMS with SP1 require different security levels by default and may not be the same individual. Now we will have to give Cluster Administrator Exchagne rights to avoid “Bad things Happening”… Thankfully SQL and other Microsoft produts don’t have an issue with CluAdmin/Cluster.exe. Nor do … Continue reading Exchange Server 2007 & CluAdmin/Cluster.exe Bad Things can Happen?
This past weekend I ran into a few issues with Exchange Server 2007 and wanted to share, so anyone with them won’t have to call Microsoft PSS and go through the fun (ok, not really fun…) that I went through. Partition in Time with CCRYou have a partition in time, but what does that mean. You lost a node or the witness, and while that was happening the remaining node/witness thought a change was made. When the down node/witness came back it detected that a change has occurred and killed the entire cluster. This is by design. Now, how do … Continue reading Exchange Server 2007 SCC/CCR lessons learned
Sometimes I think that the movie Conspiracy Theory should have been about the software industry today. What has become of it lately? Here is what I believe: · I believe the Anti-Virus companies write all the viruses. · I believe most software is way over priced. · I believe we now alpha test software for vendors · I believe we beta test when service pack 1 comes out. · I believe 1.0 is not the standard to avoid, RTM (release to manufacturing/gold code) is. · I believe we get the final, ready for the world product when service pack 2 … Continue reading Observations about the software industry today
I love taking Microsoft exams because I learn so much. I learn what Microsoft feels are the important product features that everyone show know. I learn different ways to do common tasks within the product, let’s face it sometime we only know as much as our peers. I also learn exactly where I stand on the product, and what I really need to work on. As I get older though I am either getting smarter or lazier, take your pick. I simply don’t study for the exams anymore. Sorry, but I don’t. I take the exam to learn the question … Continue reading Exchange Server 2007 MCP Exams – Notes from the field
Have you tried to install Exchange Server 2007 yet? Clustering is different. First of all Exchange Virtual Servers (EVS) are gone, replaced with Clustered Mailbox Server (CMS). You now have two options for clustering, Single Copy Cluster (meaning one CMS per server really) and it is not the default installation. The default is now Continuous Cluster Replication (CCR) which is something new to Exchange Server 2007, You still install and configure clustering first, then install Exchange. But passive and active nodes are supposed to be handled differently now. And active/active clustering is simply not allowed anymore [:D] I would use setup.exe … Continue reading A few tips for Exchange Server 2007 SCC & CCR clustered installations
But if you want to test failover clustering…. Standard SCSI based clustering will no longer work (yes I tested it, no go). Rocket Division StarWind will be the product you want to use to test Failover Clustering. http://www.rocketdivision.com/wind.html You will have to wait until the June 2007 time frame while they make it work with Beta 3. FalconStor iSCSI Storage Server http://www.falconstor.com/en/solutions/?pg=Products&sb=iSCSI I am not sure when they will support it. Microsoft bought StringBean (http://www.stringbeansoftware.com/downloads_update2_0.asp) which has a great WinTarget program. The program is now part of Windows Unified Data Storage Server and it called Microsoft iSCSI Software Target. That one works today, if … Continue reading Windows Server Codename "Longhorn" Beta 3 is out
Clusters are Highly Available and should never be considered Fault Tolerant.Highly Available = is when I come anytime my wife calls me.Fault Tolerant = Marriage.You don’t want to be married to you SQL/Exchange Cluster 🙂 You do want it around whenever you need it though. Active/Active = when your cluster is too busy for its own good.Active/Passive = one worker, one manager, you decide which is which.Node = Clustered computer, could also be the worker who sits in a cube, not to be confused with Dude.Virtual Server = this is kind of like be on a telecom at work, only … Continue reading Clustering terms made easy
Don’t panic, but you do have a problem. You look under Services and the Cluster service is running on the nodes. Open Cluster Administrator from one of the nodes, but don’t use the name of the cluster, the node name or an IP address, use a period (.). This will open it using a Local Procedure Call (LPC) and not a Remote Procedure Call (RPC). See Cluster Administrator Switches for Connecting to a Cluster for complete switch details. Now with Cluster Administrator open, expand the Cluster group and attempt to start any failed resources. Whatever keeps failing should give a … Continue reading Your Cluster won’t start and you can’t get into Cluster Administrator
By now you are aware that SP2 is out for Windows Server 2003 and R2. I have already seen quite a few posts in the public newsgroups where people are not aware of a few things. The Good It is a really good idea to backup your system before you attempt any major update or service pack. Remember your backup is only as good as your restore. Or as Geoff N. Hiten SQL MVP and SQL God says “Until you test a backup by restoring, you don’t have recovery plan, you have a recovery hope.” Another good idea, read the … Continue reading Windows Server 2003 Service Pack 2 – the good, the bad, and the ugly
The 2007 MVP Summit in Redmond/Seattle was awesome. Lots of great content. Here is what I learned: 1) SQL 2005 can cluster with Standard Edition (ok I knew that). What I learned was that you can have multiple SQL instances (that run on 2 nodes only) within any size cluster. So, if you have a 4 node cluster you can run 2-3 instances with multiple copies of SQL 2005 Standard Edition. Cool! Think of the savings. 2) Exchange 2007 Clustering is way cool and different, but in a good way. 3) Windows Server 2003 can support GPT – http://support.microsoft.com/kb/919117 – and volumes larger … Continue reading What I learned at the MVP Summit last week – and I can tell you about!
