Hello All,
First thing, the documentation on VI Toolkit :
http://communities.vmware.com/docs/DOC-4210
If you want to connect to more than one virtual center at the same time, here the starting code :
1
2
3
4
5
6
7
| $vcs = @()
$vcs += connect-viserver <vc 1>
$vcs += connect-viserver </vc><vc 2>
# You could add many as you need...
# Command example : Snapshot all VMs across all VirtualCenter servers.
get-vm -server $vcs | new-snapshot |
Be carrefull, the command GET-VM $VCS will not return the same values than GET-VM.
If you use GET-VM, you will receive the VM List only for the Virtucal Center that you connect last. If you want the get all the VM of your different virutal centers, you absolutly need to add the parameter -server $vcs to you command. In a general way, don’t forget to add -server $vcs to every command than you use with the VI Toolkit.

Dear All,
Here a new little powershell script that creates an event 6970 in the event viewer when there is more than X accounts locked in less than Y minutes. Now, you just have to create a new rule in SCOM that collect event with the ID6970 and schedule that script to run every 10 minutes.
Thanks to that you can be alert when there is an attack attempt to your Active Directory.

Hello everyone,
Some weeks ago, I had to deploy SCOM Agent on more than 350 windows servers at the time. For that, I wrote a PowerShell Script where you just have to give a server list in input and the name of your RMS/MS . And that’s it, the script is performing the agent installation for you. A CSV file will be generated as output with the agent installation status of each servers.
Concerning the right management, you have to ensure that the Default Action Account using on the server that you will use for deploying the agents (MS normally), has administrative right on the servers that you want to add in SCOM. For that, and the duration of the deployment only, use a Domain Admin Account as the Run As Account of your MS/RMS.
The script :

There are two ways to solve this problem, you can recreate the /dev/random file or do a manual agent install.
For both fixes, clean off the partially installed agent using the commands
- rpm -e scx
- rm -rf /etc/opt/microsoft/scx
Then if you want to make it so that discovery will work from the wizard use the commands
- rm /dev/random
- mknod -m 644 /dev/random c 1 9
- chown root:root /dev/random
A manual install requires copying the appropriate package from %Program Files%\System Center Operations Manager 2007\AgentManagement\UnixAgents to the Unix\Linux machine and installing it directly.
After fixing the install issue, switch the /dev/random file back to a signed random file using the commands:
- rm /dev/random
- mknod -m 644 /dev/random c 1 8
- chown root:root /dev/random
