VMware Aria Suite

Issue/Introduction

Symptoms:

Upgrade precheck for VMware Aria Automation fails with the error "IP 'Aria_Automation_IP' does not uniquely resolve to Hostname <hostname>."
The DNS server has both forward and reverse lookup of Aria Automation nodes.

Environment

VMware Aria Suite Lifecycle 8.x

Cause

This error can occur when the DNS server contains the DNS entry for the VMware Aria Automation appliance, but there is a case mismatch between the hostname stored in the appliance and the corresponding entry in the DNS server.

Validating DNS

SSH into the appliance with the IP Aria_Automation_IP available on the error message using the root account.
Compare the cases of FQDN returned by the below commands, if the case formats are different, note down the output and case format of the first command below.

hostname

/usr/bin/dig +noall +answer -x 'Aria_Automation_IP'

Resolution

This issue will be resolved in VMware Aria Suite Lifecycle 8.14 Patch 1 and later

Workaround:

Update the DNS record of the Aria Automation node on the DNS server with the same case format as noted down in the Validation step.

Step-by-Step Explanation of Ballooning, Compression & Swapping in VMware

🔹 Step-by-Step Explanation of Ballooning, Compression & Swapping in VMware ⸻ 1️⃣ Memory Ballooning (vmmemctl) Ballooning is the first memory reclamation technique used when ESXi detects memory pressure. ➤ Step-by-Step: How Ballooning Works 1. VMware Tools installs the balloon driver (vmmemctl) inside the guest OS. 2. ESXi detects low free memory on the host. 3. ESXi inflates the balloon in selected VMs. 4. Balloon driver occupies guest memory, making the OS think RAM is full. 5. Guest OS frees idle / unused pages (because it believes memory is needed). 6. ESXi reclaims those freed pages and makes them available to other VMs. Why Ballooning Happens? • Host free memory is very low. • ESXi wants the VM to release unused pages before resorting to swapping. Example • Host memory: 64 GB • VMs used: 62 GB • Free: 2 GB → ESXi triggers ballooning • VM1 (8 GB RAM): Balloon inflates to 2 GB → OS frees 2 GB → ESXi re...

Quick Guide to VCF Automation for VCD Administrators

Quick Guide to VCF Automation for VCD Administrators VMware Cloud Foundation 9 (VCF 9) has been released and with it comes brand new Cloud Management Platform – VCF Automation (VCFA) which supercedes both Aria Automation and VMware Cloud Director (VCD). This blog post is intended for those people that know VCD quite well and want to understand how is VCFA similar or different to help them quickly orient in the new direction. It should be emphasized that VCFA is a new solution and not just rebranding of an old one. However it reuses a lot of components from its predecessors. The provider part of VCFA called Tenenat Manager is based on VCD code and the UI and APIs will be familiar to VCD admins, while the tenant part inherist a lot from Aria Automation and especially for VCD end-users will look brand new. Deployment and Architecture VCFA is generaly deployed from VCF Operations Fleet Management (former Aria Suite LCM embeded in VCF Ops. Fleet Management...

ESXi Host Troubleshooting Checklist

🛠️ ESXi Host Troubleshooting Checklist (With Complete Log Locations) ✅ 1. Host Status & Connectivity Check host state in vCenter (Connected / Not Responding / Disconnected) Review CPU, RAM, and datastore usage Validate HA/DRS recommendations ✅ 2. Hardware Health Monitor hardware sensors (CPU, DIMMs, fans, PSU, RAID) Check RAID controller logs via vendor tools View hardware status in: vCenter → Monitor → Hardware Health DCUI → Hardware Status ✅ 3. Network Validation Verify vSwitches, Port Groups, NIC teaming, VLAN tagging Check vmkernel ports (mgmt, vMotion, iSCSI, vSAN) Test reachability using: Shell vmkping < IP > Show more lines Validate physical NIC status and link speed ✅ 4. Storage & Datastore Checks Confirm datastore accessibility Rescan storage adapters (iSCSI/FC/NFS) Validate multipathing (Round Robin / Fixed / MRU) Check datastore latency with esxtop ✅ **5. Critical Logs & Their Locations (Full List) Here are key ESXi log files that every VMware adm...
