VMware vSphere 5.x and Windows 2012 possible Data corruption

POSSIBLE DATA CORRUPTION ISSUE, MUST READ! Sorry for starting this way, but this is a big deal, and I wanted to make sure you catch this when scanning through the weekend spam. Apparently, VMware issued a support KB article on this issue a few weeks ago, but it totally flew under the radar (I have not seen a single tweet or blog about this). In short, any data flowing through the VM network stack may get corrupted - including file copies, remote clients interactions with databases, any client-server or multi-tiered apps. The scariest...

Use System Configuration Tool to Solve Problems

Any IT Pro can tell you that solving problems is as much as art as it is a science. I don’t think you can ever have enough tools in your admin toolkit. Here’s one that ships with Windows that you may not know about but one which I think can be very useful. This tool has been around for awhile on both client and server platforms. For the sake of this article I’m going to demonstrate using it on Windows 7, but everything should equally apply to your servers. System Configuration Under Administrative Tools you should find a link to... [Lire la suite]

Resolved: Slow booting of ESXi 5.0 when iSCSI is configured

y colleague Cormac posted an article about this already, but I figured it was important enough to rehash some of content. As many of you have experienced there was an issue with ESXi 5.0 in iSCSI environments. Booting would take a fair amount of time due to the increase of the amount of retries in the case creating a connection to the array would fail. This is what the log file would typically look like:iscsid: cannot make a connection to 192.168.1.20:3260 (101,Network is unreachable)iscsid: Notice: Reclaimed Channel (H34... [Lire la suite]

vSphere 5.0 + View 5.0 vMotion Fail

There is a bug in the way the object buffer cache size is calculated for vMotion. This bug only appears with Hardware version 8 virtual desktops with large screen resolutions, however only if 3D is disabled. When 3D is enabled ESxi5 takes the necessary screen objects into account in the calculations and allocate sufficient buffer for vMotion to succeed. But with 3D disabled it doesn’t calculate the values correctly for the buffers. This is will impact any VM with large screen size. If you have a peek at my previous post you will be...
