Following on from writing about the VCAP5-DCA objectives, I intend to cover a few scenarios based on some of those objectives, particularly those that I feel the need to go…
I’ve written about deploying ESXi hosts using AutoDeploy whilst covering the VCAP5-DCA objectives, but I didn’t go into stateful deployments or stateless caching. By default, a host provisioned using AutoDeploy…
When you install ESXi, a default certificate for the host is generated. This is a ‘self-signed’ certificate and as such will not be trusted by default in it’s communications with…
This will be a quick post to address the VCAP5-DCA objective of using esxtop/resxtop and vscsiStats to identify storage performance issues on an ESXi host environment. I covered both of…
I’ve written previously about VMFS resignaturing, so rather than cover the same ground here, I’ll walk through an example of working with/troubleshooting a snapshot lun. To start with, you can…
NFS can be used as an alternative to a VMFS datastore for storing virtual machines. When using an NFS share as storage for virtual machines, there are a few things…
I’ve written previously about configuring a Windows 2008 NFS server. Whilst looking at the NFS related objectives for the VCAP5-DCA exam recently, I needed a NFS server for use in…
When troubleshooting storage and multipathing issues it is often necessary to check log files to fully understand where the problem lies. Most commonly the log to check is the vmkernel…
This will be a short post intended to cover the VCAP5-DCA objective of using the DCUI and ESX cli/shell to monitor and troubleshoot a host. I’ve written a lot around…
