A full /storage/log partition on a vCenter Server Appliance is not just a housekeeping problem. It is a management-plane risk. In a standalone vSphere environment, it can interrupt administration, log collection, patching, and service stability. In VMware Cloud Foundation, the blast radius is larger because vCenter is tied into SDDC Manager workflows, workload domain lifecycle […]

There are storage incidents where the host looks half-recovered. The fabric switch is back online. The link light is good. The array port is healthy. Some paths may even show up again. But inside ESXi, the storage view still does not match reality. A datastore has fewer paths than expected. An RDM-backed workload is not

Virtual machine network problems rarely arrive with a clean label. The ticket usually says something like “the VM is unreachable,” “the application cannot connect,” “ping fails,” “internet access is down,” or “VMs on different hosts cannot talk.” The underlying cause might be inside the guest OS, on the VM’s virtual NIC, in the port group,

vCenter certificate failures tend to show up at the worst possible time: during an upgrade precheck, after a maintenance window has already started, when services will not start cleanly, or when a certificate alarm has been ignored long enough to become someone else’s emergency. The mistake is treating certificate recovery as a button-click exercise. The
