When I started my preparation work, which mainly consisted of me testing scripts in my lab environment, it dawned on me that not all of my Production VM’s have VMware Tools installed. So how can I go about…
We embarked on patching all of our hosts to 6.7 Update 3, which included our vSAN clusters. The first vSAN cluster to get the update is our four-node management cluster. After patching two hosts to 6.7 Update 3 (build 14320388), we noticed several vSAN alarms. At first I thought this was something similar to my…
Ah, another lovely Tuesday. The Monday fires have been put out, TPS reports have all been filed (with the new cover letter no less), and now we can get back to focusing on innovating. Not so fast. It looks like one of our hosts has disconnected from vCenter. This should be fun! All of the…

I love it when USB devices fail. But wait, something didn’t add up correctly. It was my understanding that none of my hosts are USB…
Supported Source Environments You can migrate VMs from the following source hypervisors to AHV: VMware ESXi Microsoft Hyper-V Unified Extensible Firmware Interface (UEFI) Support Information In the current AOS and AHV releases, the UEFI implementation is limited. The following table describes the level of support available for various usage scenarios: Scenario Support Level Generation 2…
A storage container is a defined subset of available storage within a storage pool. Storage Containers allow you to apply rules or transformations such as compression to a data set. Logical segmentation of SP containing groups of VM’s/files (vDisks). Typically have 1:1 mapping with datastore VMware Storage presented via NFS (default) or iSCSI AHV Storage…
Cloud-init Cloud-init is a utility that is used to customize Linux VMs during first-boot initialization. The utility must be pre-installed in the operating system image used to create VMs. Cloud-init runs early in the boot process and configures the operating system on the basis of data that you provide (user data). You can use Cloud-init…
Hardware components (nodes and disks) can be removed from a cluster or reconfigured in other ways when conditions warrant it. Note: If the Data-at-Rest Encryption is enabled then before removing a drive or node from a cluster, test the certificates again by clicking Test all nodes and ensure that testing is successful and the status is Verified. In…
