UCS: Unable to communicate with Flexible Flash controller

by on May.28, 2014, under UCS, Vblock, VMware

For all of you who are using Cisco UCS C220 M3 server and Flexible Flash controller with SD card beware that there is a bug in firmware prior to 1.5(3a)

The problem shows up as timeout error for FlexFlash controller. The interesting part is even though there is a problem with the FlexFlash, CIMC still is showing that overall Server Status as good:
Once you log-in into CIMC you will not see that there is a problem:

VMware: Cannot create Resource Pool, the option is greyed out

by on Jun.14, 2013, under Vblock, Virtualization, VMware

  2. Tick Turn On vSphere DRS click OK.

Installing Veeam FastSCP 3.0 on Windows 7 beta

by on Mar.25, 2009, under VMware, Windows 7

So because Windows 7 is still in Beta, Veeam FastSCP 3.0 does not support it, but it does not mean that you cannot use it.
While trying to install the application on Windows 7 beta you’ll get the following message.

To get around it you can use Winrar to extract the package and launch FastSCPSetup.msi file.
If you don’t have Winrar and don’t want to install it use command line to extract the content of veeam_fastscp_3.0.exe.
the syntax looks like this:
veeam_fastscp_3.0.exe /C /T:(full path)
The following example extracts everything to c:\temp\veeam

VMware: Add permissions are missing in ESX 3.5

by on Jul.15, 2008, under Virtualization, VMware

So yesterday I wanted to add permissions to a resource pool on ESX 3.5 but I could not do that because the option was not there.

That looked strange because I was able to do that on other ESX server that was running version 3.0.2
Apparently for some reason VMware removed that option starting version 3.5. so the only way to add permissions is to used Virtual Centre which of course you have to buy. Can I ask why VMware did that ?
