UCS: Unable to communicate with Flexible Flash controller


28 May

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:

No Errors

but once you click on Storage tab you’ll get error message:

Error: Unable to communicate with Flexible Flash controller: operation ffCardsGet, status ERROR_TIMEOUT

In the logs you’ll see: (more…)

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

Installing Veeam FastSCP 3.0 on Windows 7 beta


25 Mar

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

Building Cheap Virtual Test Environment PART1: Choosing hardware


17 Nov

I’ve deicided that it is time for me to build my own testing environment at home. I’ve been playing around with Vmware server and MS Virtual server for a while and they work OK to some extent. With Vmware I had 2 VM running with server os, but the speed of the whole system was quite slow as the hard drive LED was constantly on. To make thing better I’ve bought external USB drive and was creating VMs on it and that improved performance a lot, but then if I tried to create a VM with DB on it then things were getting slow again.
So after VMware made ESXi free I was thinking of getting my own server that I could use as a virtual testing lab 🙂 (more…)

VMware: Add permissions are missing in ESX 3.5


15 Jul

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 ?
