VMware vSphere & ESXi: tools, error fixes and guides
Everything we publish for VMware vSphere and ESXi in one place: a searchable error reference that tells you how to resolve each failure, a PowerCLI command generator that writes the script for you, and step-by-step troubleshooting guides for the problems that take a host or a cluster down. Free, no signup, browser-based.

Search any vSphere or ESXi error by code, message or symptom — PSOD, APD, vMotion, host not responding — and get the cause plus the exact resolution, with the esxcli or PowerCLI command and a verification step.
VMware tools
Interactive, client-side helpers for daily vSphere work.
Troubleshooting guides
Long-form, hands-on, each with copy-paste commands and a custom diagram.
Live ESXi Purple Screen of Death (PSOD): Diagnose and Recover Read the exception and backtrace, tell driver from hardware from heap exhaustion, capture the coredump, recover the host and prevent recurrence. With an annotated purple-screen diagram. Live ESXi Host Not Responding / Disconnected in vCenter The fix order that resolves it fastest: confirm the host is up, restart hostd and vpxa, free a full log partition, check ports 902 and 443, then reconnect or re-add.
