vRealize Operation Manager 6 （又叫vROps）是vCenter Operation Manager的全新版本，我从vCenter Operation Manager还是1.0时就开始使用了，很喜欢自我学习和动态阀值这两个功能。但是这款产品只能监控虚拟层面，如果可以监控存储层面就完美了。在比较大的vSphere环境中虚拟机是共享ESXi数据存储（datastore）的，如果少数虚拟机产生很高的IO，可能会影响到其他处于同一个存储上的虚拟机。想象一下，如果你有100个LUN跑在一个NetApp存储上，300个虚拟机在使用这100个LUN，某日用户说他们的虚拟机很慢，但是他们并没有跑什么应用，这时候就会比较难判断到底是哪儿出了问题，因为虚拟机可能共享同一个数据存储（datastore），数据存储存建于LUN上，LUN 可能来自某个聚合（Aggregate），并且多个LUN可能来自同一个物理磁盘。vCenter Operation Manager 在5.x时代有提供一款NetApp存储监控组件，但问题是很难把vSphere的数据存储（Datastore）和NetApp存储的设备关联起来。
Windows Server 2012, the biggest competitor of VMware vSphere. There are adequate reason to use Hyper-V 2012 instead of vSphere 5.x, but it’s still very hard to for newbie, we spend more than 30 hours to try figure out how to create cluster on SCVMM 2012 SP1, the software is easy to install, but hard to configure. I saw “failed” everywhere, it’s not a mature product in my view.
We installed Windows Server 2012 data center edition on HP BL460, storage is NetApp FAS2240 (Maybe wrong, I’m not storage guy). We got following error message when we created Hyper-V Cluster on SCVMM2012 SP1.
VMM is unable to complete the request. The connection to the VMM agent on the virtualization server (xxx) was lost.
Unknown error (0x80338029)
Ensure that the Windows Remote Management (WS-Management) service and the VMM agent are installed and running and that a firewall is not blocking HTTPS traffic.
This can also happen due to DNS issues. Try and see if the server (dcahyv04.amat.com) is reachable over the network and can be looked up in DNS. You can ping the virtualization server from VMM management server and make sure that the IP address returned matches the IP address locally obtained from the virtualization server.
If the error still persists, restart the virtualization server, and then try the operation again.
SCVMM job failed on Mounts storage disk on xxxx.
Initially I thought that’s something wrong with services, I checked the mentioned Windows Remote Management service, but it’s up and running. Then I noticed WINS servers was not set, but still no lucky.
Why the job always failed on mount storage? Maybe something related to disk operation? SCVMM server is remote server, it must be operates disk remotely, so I tried connect Hyper-V server by Computer Management tool remotely, it show me RPC is unavailable when I click Disk Management node. Aha…firewall problem, that’s because SCVMM server disabled firewall, but Hyper-V server enabled, the RPC ports was blocked by client side.
Sometimes cluster creating can be successful after I disabled firewall, but still Hyper-V server looks like hard to mount storage.
Since SCVMM mount/unmount storage on each Hyper-V hosts during cluster creating, it takes very long time to mount storage before the job failed, we suspected that’s something related to storage, finally, we installed NetApp Host Utilities 6.0.1 and NTAP MPIO 4.0.1 to solved the problem.
To summarize, you must enable remote management for Hyper-V host, such as Remote Register service…etc, allows required ports in Windows firewall and storage MPIO plugin should be installed as well. BTW, you should disable UAC on Windows Server 2012, it’s different with Windows Server 2008, check http://social.technet.microsoft.com/wiki/contents/articles/13953.windows-server-2012-deactivating-uac.aspx.
That’s just first step to make Hyper-V successful. 🙂
NetApp Virtual Storage Console is my favorite to manage and backup data on NetApp attached ESXi host, there is lot of benefits to secure VM data more efficient.
The installation is pretty simple, and very less resource it requires, you can even install it on a multi-role virtual machine. But the first headache maybe the backup log.…
The default report URL is IPv6 in NetApp Virtual Storage Console. You have to add parameter in wrapper.conf file manually. Here is detail steps:
This procedure has to be repeated after NetApp Virtual Storage Console is upgraded.
1) Shut down SMVI server (via Windows service).
2) Open the wrapper.conf in C:\Program Files\NetApp\Virtual Storage Console\smvi\server\etc
3) Locate section
Java Additional Parameters wrapper.java.additional.1=-XX:MaxPermSize=128m wrapper.java.additional.2=-Dcom.sun.management.jmxremote wrapper.java.additional.3=-Dcommon.dir=. wrapper.java.additional.4=-Dorg.apache.cxf.Logger=org.apache.cxf.common.logging.Log4jLogger
4) Add following line:
5) Start SMVI server (via Windows service).
