You will receive a message, searching for management pack Microsoft.SystemCenter.Library with Version 6.1.7221.61:

Unfortunately you will found only version 6.1.7221.0 on your disk. Microsoft didn’t published the newer version as separated management pack file (*.mp).

To solve this open your management pack with a text- or xml-editor and change from:

Change string value to integer in a SNMP monitor

0

When you create an SNMP monitor in SCOM 2007 R2, SCOM assumes that the values are in STRING-format. So if you define, that your monitor should check an SNMP-OID to be greather than 70 and the SNMP OID gives a value of 100 back, your monitor will generate an error. To correct this, you have to tell your monitor, that it’s an INTEGER-value. Unfortunately, you can’t do this with SCOM Console.

The easiest way to do this, you have to export your management pack and open it with the SCOM Authoring Console. read more

ESXi 4.1 Default-Screen

The ESXi 4.x installer utilizes the default blocksize of 1MB when creating VMFS volumes, allowing for storage of files 256GB and under. This default VMFS Datastore cannot be easily reformatted with a higher blocksize as it contains the Service Console VMDK file. But to store files greather than 256 GB (ex. VMDK), you have to use a blocksize greather than 1 MB on your partition. If you use your system-partition for saving VMDK-Files greather than 256 GB, you have to change the blocksize of your system-partition. Unfortunately VMware doesn’t give you the possibilty to do this during the installation. So you have to do this with a trick after the installation: Install the VMware ESXi 4.x host as always. After the installation follow this steps: ESXi 4.1 Default-Screen Press the Funktion-Key F2 ESXi 4.1 Logon-Screen Logon with your root-account. Troubleshooting Options Select Troubleshooting Options. Select Enable Local Tech Support. After you enabled the local Tech Support, press two times the Key ESC, to exit to the Default Screen. ESXi 4.1 Default-Screen Press the Key-Combination ALT+F1 to enter the local Tech Support. You have to logon again on the console screen. After you loged in, run the follow command: You will receive the informations about all installed Drives: Now run this command:

For <BLOCKSIZE> use the value from the next table. For <DRIVE-ID> use the value received from the last command (marked yellow in example):
block size maximum file-size on vmfs3
1 MB 256 GB
2 MB 512 GB
4 MB 1 TB
8 MB 2 TB
The process did run for around 20 seconds on my 1 TB disk. After succesfull running, press the Key-combination ALT+F2, to exit to the default window. Please disable now the Local Tech Support and make a reboot.
