Reading Time: 3 minutesFor 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: 2 minutesWith 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: 3 minutesWith 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 […]

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 […]
