Log in ESXi host suing IP address and root and password. Access via SSH to delete the datastore from there, but these two datastores were not listed. I want to build a solid homelab that will assist me in aspects of systems administration so I didn’t want to risk everything by running the wrong array. For more information, see ESXi hosts without swap enabled cannot be added to a VMware High Availability Cluster. Let’s now come to the actual scenario there were multiple hosts are there & multiple LUN’s were mounted as datastore to all the hosts. To give some greater context, see my previous post. I made the decision to not live such a risky lifestyle and blow away the array and configure it for RAID-1. Your email address will not be published. If the ESXi host logs are still located in the VMFS datastore (Scratch Location), we may need to check out if the datastore is specified as a location of logs in the ESXi host settings.

As a result, although you can use local storage to create VMs, you cannot use VMware features that require shared storage, such as HA and vMotion. Your datastore is a local transport type (such as Block or Parallel) and you are attempting to extend it with a datastore of a shareable transport type (such as Fibre Channel or iSCSI), or vice-versa. Today while working on one of the site. However, the NFS storage stays available on the network level. If you right-click on a ESXi host to launch the wizard, the datastores you select will be mounted on only that ESXi host. When the primary host in a VMware vSphere® High Availability cluster cannot communicate with a secondary host over the management network, the primary host uses datastore heartbeating to determine whether the secondary host has failed, is in a network partition, or is network isolated.
