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 […]
