Monitoring Fedora Core 4 with SCOM 2007 R2 – Part 1

earthFedora bases upon Red Hat Enterprise linux which is supported by SCOM. Fedora Core 3 was the base of  RHEL 4 and Fedora Core 6 RHEL 5. In this blog posts I will try to convince SCOM that the Fedora 4 based Asterisk telecom system is a RHEL 4.

First we have to install the RHEL4 scom agent manual onto the systems. In this case we had to install the OpenSSL library, too. Additional we add the scom user account to the system.

After that we sign the local created certificate by the scom server and replace it on the Fedora system.

Now we can test the connection from the SCOM server with this winrm command:

winrm enumerate http://schemas.microsoft.com/wbem/wscim/1/cim-schema/2/SCX_OperatingSystem?__cimnamespace=root/scx -username:scomuser -password:yourpassword -r:https://your.fedora.system:1270/wsman -auth:basic -encoding:UTF-8

The output shows detail information about the OS:

SCVMM/Hyper-V: Löschen von VMs

timerKann mir einer das mal erklären? Löscht man in Hyper-V eine VM, die Snapshots hat, dann werden erst alle Snapshots gelöscht, also in das Hauptfile zurückgeschrieben und dann die entsprechende Disk. Was für einen Sinn macht das?

Besonders extrem wird es, wenn man ein Storage Migration mit SCVMM (System Center Virtual Machine Manager 2012) macht. Dabei wird eine neue VM angelegt, die Disks kopiert und dann die alte VM mit den Disks gelöscht. Was dann bei einer VM mit Snapshots passiert kann man sich denken:

Ansicht des Jobs im SCVMM 2012:

scvmm

Wie man sieht wurden die Disks innerhalb 3 Minuten kopiert und jetzt (ca. 14:05) hängt er immer noch beim Entfernen der VM.

In der Hyper-V Konsole sieht es zu dem Zeitpunkt so aus:

hyper-v

Destroying ist bei 25% Smiley

Ich kann mir den Sinn davon nicht erklären. Vielleicht irgendein anderer hier??

Re-Import VMs into Hyper-V

toolsNormaly you can only import a Virtual Machine (VM) into Hyper-V if you have exported it. If you lose your Hyper-V settings or have to import it into a new Hyper-V Server in case of a desaster recovery than you can use the steps descripted in this (and other) blog post: http://blogs.msdn.com/b/robertvi/archive/2008/12/19/howto-manually-add-a-vm-configuration-to-hyper-v.aspx

The problem is that you have to handle many long pathes and cryptical GUIDs. I had to do that for a bunch of different VMs and being chronical lacy I created three batch files for it:

  1. importVM.cmd “GUID” “Path to Virtual Machine” creates the link and corrects the permissions on the link and the vm folder
  2. importSnapshot.cmd “SnapshotGuid” “VMGuid” “Path to Snapshot” creates the snapshot link and the right permission.

Not very impressiv? Well, the third batch files combines this two scripts:

  1. addMachine.cmd: Takes the basis path (the path where the sub-folder Virtual Machine, Snapshots exists) and extracts the VM-GUID, all Snapshots-GUIDs and the other pathes to automaticly create the links and permissions.

So with one simple command (addMachine.cmd C:\ClusterStorage\Volume4\VM1) you can import the complete VM.

— addMachine.cmd ——
