Just read through 1 of the KB here which referring to the potential risk to create a purple screen scenerio during the vSphere 5 upgrade while you ESX host update 2 could potential conflict with the vCenter 5.

You may encounter an issue where:

  • You have recently upgraded your vCenter Server to version 5.0
  • You have hosts of minimum version ESXi 4.0 Update 2 (build 261974) and maximum version ESXi 4.0 Patch 9 (build 360236) in your vCenter Server inventory
  • After the vpxa agents are upgraded, the ESXi 4.0 Update 2 hosts experience a purple screen that includes this error:NOT_IMPLEMENTED bora/vmkernel/filesystems/visorfs/visorfsObj.c:3391
Solution
This issue has been resolved in ESXi 4.0 Update 3. To avoid this issue, upgrade all affected hosts to at least ESXi 4.0 Update 3 (build 398348) before upgrading vCenter Server to 5.0.

VCP 5 Exam Experience

Posted on October 16th, 2011 in Tips, Training, Virtualization, vSphere | 19 Comments »

I just did my VCP 5 Exam las 2 days ago. I would like to share some of my experience to you, who may plan to go for the exam. Currently, VMware will allow all VCP 4 to proceed to direct exam upgrade path for VCP 5. You need to get your VCP 5 before end of Feb 2012. If you are failed to obtained the VCP 5 after end of Feb 2012, you will require to attend the official training before you can sit for the exam.

Well, I would like to share some of my thought and experience for the VCP 5 exam. I had passed it but it took me more than 1.5 hours as I recheck all the 80 questions after I answered the 1st round. I used to be the 1st VCP 5 in Malaysia, but I am not sure whether I am going to be 1st VCP 5 again in Malaysia. The exam is never easy as most of the questions are deep dive into specified technology area, and you will require a lot of hands on deployment, support administration or lab environment to visualize or provide the correct answer. Simon Long’s blog may had helped little bit, but to my surprise, most questions are relevant to the administration experience on VMware stuffs.

Cisco and VMware Submitted VXLAN for Open standard

Interesting announcement from Cisco and VMware during the VMworld 2011 which was regarding the VXLAN capability. Both company had invited a group of product principle together to submit the VXLAN to IETF for approval as a standard for future.

Let’s talk a little bit more about what is VXLAN and why do we need that. As of today, DR solution are commonly deploy by every enterprise environment. Did you realize 1 of the biggest challenge which always happen on the DNS record, hard coded IP segment, subnet and VLAN which always require human interaction to manually change it, to allow a success fail over of the DR scenario? Well, I think this is just 1 of the major issue commonly face. With Cisco Nexus 7000 come with OTV (Overlay Transport Virtualization) which allow you to stretch the Layer 2 traffic over Layer 3, with minimal bandwidth requirement. Cisco had done a great job to the enterprise to address this, which now you can have both side learning the same VLAN, Subnet and ip address. A DNS and ip changes is no longer require as both end are transparent with similar VLAN.
