Reading Time: 2 minutes With the new HA implemenation, something has changed also in the advanced options with new parameters, but also with some that now are no more available. For a list see Supported vSphere 5.0 Advanced Options. One options that has been removed “das.failuredetectiontime”. The reason is well explained in Duncan’s HA Deep Dive: I know many of you used this advanced setting to tweak when the host would trigger the isolation response, that is no longer possible and needed to be honest. If you’ve closely read my other articles you hopefully picked up on the datastore […]

Reading Time: 3 minutes For a list of all objectives see the VCP5 page. Objective 6.4 – Perform Basic Troubleshooting for HA/DRS Clusters and vMotion/Storage vMotion For HA and DRS see also: HA Deepdive and DRS Deepdive. Identify HA/DRS and vMotion requirements (similar as vSphere 4.x) See the vSphere Availability guide (page 11) and the vSphere Resource Management guide (page 51). Basically a shared storage is required, some network configurations, and (for DRS and vMotion) a CPU compatibility or the EVC function in the cluster. Verify vMotion/Storage vMotion configuration (similar as vSphere 4.x) See the vCenter Server and Host […]

Reading Time: < 1 minute For a list of all objectives see the VCP5 page. Objective 6.3 – Perform Basic vSphere Storage Troubleshooting Verify storage configuration (similar as vSphere 4.x) See the vSphere Troubleshooting guide (page 45). A minimum of storage enterprise knowledge is also required. Troubleshoot storage contention issues (similar as vSphere 4.x) See the vSphere Troubleshooting guide (page 45) and vSphere Storage guide (page 24). Troubleshoot storage over-commitment issues (similar as vSphere 4.x) See the vSphere Storage guide (page 183) and VCP5 Exam Prep – Part 3.1 (in the thin provisioning points). Troubleshoot iSCSI software initiator configuration issues (similar […]

Reading Time: < 1 minute So the last VCDX4 defense opportunity will not be Frankfurt, as written in a previous post… By popular demand, the VCDX program has added another opportunity to attempt VCDX.  This will take place in the Toronto, Ontario, Canada, metropolitan area during the week of May 7 through 11, 2012.  The exact address will be provided to registered candidates who are accepted to defend. Registration will open on February 20, 2012.  Applications are due March 12, 2012. See the full announce on the VMware Community: http://communities.vmware.com/thread/330361

Reading Time: < 1 minute Some hours ago I have received an e-mail from VMware Technical Certification Team to my VCP5 certification in my official transcript: The VMware education transcripts will now include your VMware technical certifications. Your online transcripts will reflect your VMware Certified Professional on vSphere 5 status as soon as you: –  Confirm your shipping address –  Consent to transcript release –  Accept the VMware Certification Agreement With this, all certifications are now correctly listed in the transcript… and I can take a breack… until next new certifications :) Some welcome kits are still missing (also my […]

Reading Time: 2 minutes With the new version of VMware vSphere there are some small and big changes: some products and features were removed, but also some new features were addes (for the 140 new features of vSphere 5 see: vSphere 5.0 Features and Duncan’s 50 out of 140 vSphere 5 Features Challenge). Who is out: the old ESX (the legacy ESX with the full Service Console) has gone, see: ESX and GSX are dead?! the old Converter Enterprise (integrated in vCenter Server) has gone and only the Standalone Converter remain but in this was there is not more […]

Reading Time: 2 minutes On the VMTN Blog (the official blog of the VMware Community) today there is my “vExpert Spotlight”: http://blogs.vmware.com/vmtn/2011/09/vexpert-spotlight-andrew-mauro.html How did you get into IT in  the first place? I’ve started (a lot of years ago) with a Commodore 64, but only with my first experience on a PC (with MS-DOS) I understand that this passion would also be my possible work area. During University, I also played with Linux distributions and this gave me a better understanding of Operating Systems and networking. Things are really change. Now start in IT is simpler and cheaper (I remember […]

Reading Time: 4 minutes As I’ve written in a previous post, Dell has recently released the new versions of some Equallogic’s software, included the new Host Integration Tools (HIT) for VMware 3.1 that is now compatible with vSphere 5 (it support also the Storage Clusters and VASA). The appliance and the documentation are available from the Equallogic support site. HIT/VE is distributed as a OVA file (the current version is HITVE-3.1.1.32.ova) and the deploy is the same as other virtual appliance. The VM it’s based on a CentOS 5.3 distro and it’s configured with virtual hardware 7 (so it […]

Reading Time: 3 minutes With ESX/ESXi is possible have several information from the physical hardware (with CIM) and this could be enough in most cases, especially for monitoring (with hardware health) and to gain some inventory info (like the Service Tag of a server). But for some specific tasks (like a RAID rebuild o check of the local storage, or have a detailed inventory of the physical RAM banks) is necessary use the specific native tool from the hardware vendor. For Dell servers, the tool is called OpenManage Server Administrator (OMSA) and the current version is 6.5. It is […]

Reading Time: 2 minutes For a list of all objectives see the VCP5 page. Objective 6.2 – Perform Basic vSphere Network Troubleshooting Verify network configuration (same as vSphere 4.x) See VMware Virtual Networking Concepts for basic concepts for standard virtual switches. See Objective 2.2 – Configure vNetwork Distributed Switches for distributed virtual switches. Verify a given virtual machine is configured with the correct network resources (same as vSphere 4.x) See VMware KB: Troubleshooting virtual machine network connection issues and http://damiankarlson.com/vcap-dca4-exam/objective-6-3-troubleshoot-network-performance-and-connectivity/ Troubleshoot virtual switch and port group configuration issues (same as vSphere 4.x) Use previous links. For vmkernel porgroup vmkping […]

Reading Time: < 1 minute For a list of all objectives see the VCP5 page. Objective 6.1 – Perform Basic Troubleshooting for ESXi Hosts Identify general ESXi host troubleshooting guidelines (new in vSphere 5) See the vSphere Troubleshooting guide. Troubleshoot common installation issues (new in vSphere 5) For Audodeply see the vSphere Troubleshooting guide (page 20). For other installation is most similar to old version and remember to check requiments and HCL. Monitor ESXi system health (similar as vSphere 4.x) See the vSphere Monitoring and Performance Guide (page 25). Export diagnostic information (new in vSphere 5) See the vCenter Server and Host Management […]

Reading Time: 3 minutes For a list of all objectives see the VCP5 page. Objective 5.6 – Patch and Update ESXi and Virtual Machines See also: Objective 5.6 – Patch and Update ESXi and Virtual Machines. Identify patching requirements for ESXi hosts and virtual machine hardware/tools (similar as vSphere 4.x) Each piece of software need to be patched for different reasons… but the most important are usually the security reasons. For ESXi a patch need that the host is put in maintenance mode and require a host reboot after the patch operation. All those operations can be orchestrated by […]

Reading Time: 5 minutes At the BUILD developer conference during this week, Microsoft demonstrated the new version of Windows products (and some related products, like Hyper-V and PowerShell). It is not clear if both the client and the server OS will be released at the same time (rumors say during 2012) and if they have also the same name. But I suppose that the Server OS will use the same naming of previous (so maybe Windows Server 2012?). Windows (client) 8 One curios thing is that Windows 7 and 8 are not related to their NT kernel versions: Windows […]
